HTTP Expect

Test functionality behind iris/httptest forked by gavv/httpexpect.

Documentation

Overview

Package httpexpect helps with end-to-end HTTP and REST API testing.

Usage examples

See example directory:

Communication mode

There are two common ways to test API with httpexpect:

  • start HTTP server and instruct httpexpect to use HTTP client for communication
  • don't start server and instruct httpexpect to invoke http handler directly

The second approach works only if the server is a Go module and its handler can be imported in tests.

Concrete behaviour is determined by Client implementation passed to Config struct. If you're using http.Client, set its Transport field (http.RoundTriper) to one of the following:

  1. default (nil) - use HTTP transport from net/http (you should start server)
  2. httpexpect.Binder - invoke given http.Handler directly

Note that http handler can be usually obtained from http framework you're using. E.g., echo framework provides either http.Handler.

You can also provide your own implementation of RequestFactory (creates http.Request), or Client (gets http.Request and returns http.Response).

If you're starting server from tests, it's very handy to use net/http/httptest.

Value equality

Whenever values are checked for equality in httpexpect, they are converted to "canonical form":

  • structs are converted to map[string]interface{}
  • type aliases are removed
  • numeric types are converted to float64
  • non-nil interfaces pointing to nil slices and maps are replaced with nil interfaces

This is equivalent to subsequently json.Marshal() and json.Unmarshal() the value and currently is implemented so.

Failure handling

When some check fails, failure is reported. If non-fatal failures are used (see Reporter interface), execution is continued and instance that was checked is marked as failed.

If specific instance is marked as failed, all subsequent checks are ignored for this instance and for any child instances retrieved after failure.

Example: 

array := NewArray(NewAssertReporter(t), []interface{}{"foo", 123})

e0 := array.Value(0)  // success
e1 := array.Value(1)  // success

s0 := e0.String()  // success
s1 := e1.String()  // failure; e1 and s1 are marked as failed, e0 and s0 are not

s0.IsEqual("foo")    // success
s1.IsEqual("bar")    // this check is ignored because s1 is marked as failed

Assertion handling

If you want to be informed about every asserion made, successful or failed, you can use AssertionHandler interface.

Default implementation of this interface ignores successful assertions and reports failed assertions using Formatter and Reporter objects.

Custom AssertionHandler can handle all assertions (e.g. dump them in JSON format) and is free to use or not to use Formatter and Reporter in its sole discretion.

Functions

func NewCookieJar added in v2.12.0 

func NewCookieJar() http.CookieJar

NewCookieJar returns a new http.CookieJar.

Returned jar is implemented in net/http/cookiejar. PublicSuffixList is implemented in golang.org/x/net/publicsuffix.

Note that this jar ignores cookies when request url is empty.

func NewJar deprecated 

func NewJar() http.CookieJar

Deprecated: use NewCookieJar instead.

func NewWebsocketDialer 

func NewWebsocketDialer(handler http.Handler) *websocket.Dialer

NewWebsocketDialer produces new websocket.Dialer which dials to bound http.Handler without creating a real net.Conn.

Types

type Array 

type Array struct {
	// contains filtered or unexported fields
}

Array provides methods to inspect attached []interface{} object (Go representation of JSON array).

func NewArray 

func NewArray(reporter Reporter, value []interface{}) *Array

NewArray returns a new Array instance.

If reporter is nil, the function panics. If value is nil, failure is reported.

Example: 

array := NewArray(t, []interface{}{"foo", 123})

func NewArrayC added in v2.12.0 

func NewArrayC(config Config, value []interface{}) *Array

NewArrayC returns a new Array instance with config.

Requirements for config are same as for WithConfig function. If value is nil, failure is reported.

Example: 

array := NewArrayC(config, []interface{}{"foo", 123})

func (a *Array) Alias(name string) *Array

Alias is similar to Value.Alias.

func (*Array) ConsistsOf added in v2.12.0 

func (a *Array) ConsistsOf(values ...interface{}) *Array

ConsistsOf succeeds if array contains all given elements, in given order, and only them. Before comparison, array and all elements are converted to canonical form.

Example: 

array := NewArray(t, []interface{}{"foo", 123})
array.ConsistsOf("foo", 123)

These calls are equivalent: 

array.ConsistsOf("a", "b")
array.IsEqual([]interface{}{"a", "b"})

func (*Array) Contains deprecated 

func (a *Array) Contains(values ...interface{}) *Array

Deprecated: use ContainsAll or ContainsAny instead.

func (*Array) ContainsAll added in v2.12.0 

func (a *Array) ContainsAll(values ...interface{}) *Array

ContainsAll succeeds if array contains all given elements (in any order). Before comparison, array and all elements are converted to canonical form.

Example: 

array := NewArray(t, []interface{}{"foo", 123})
array.ContainsAll(123, "foo")

func (*Array) ContainsAny added in v2.12.0 

func (a *Array) ContainsAny(values ...interface{}) *Array

ContainsAny succeeds if array contains at least one element from the given elements. Before comparison, array and all elements are converted to canonical form.

Example: 

array := NewArray(t, []interface{}{"foo", 123, 123})
array.ContainsAny(123, "foo", "FOO") // success
array.ContainsAny("FOO") // failure

func (*Array) ContainsOnly 

func (a *Array) ContainsOnly(values ...interface{}) *Array

ContainsOnly succeeds if array contains all given elements, in any order, and only them, ignoring duplicates. Before comparison, array and all elements are converted to canonical form.

Example: 

array := NewArray(t, []interface{}{"foo", 123, 123})
array.ContainsOnly(123, "foo")

These calls are equivalent: 

array.ContainsOnly("a", "b")
array.ContainsOnly("b", "a")

func (*Array) Decode added in v2.12.0 

func (a *Array) Decode(target interface{}) *Array

Decode unmarshals the underlying value attached to the Array to a target variable. target should be one of these:

  • pointer to an empty interface
  • pointer to a slice of any type

Example: 

type S struct{
	Foo int `json:foo`
}
value := []interface{}{
	map[string]interface{}{
		"foo": 123,
	},
	map[string]interface{}{
		"foo": 456,
	},
}
array := NewArray(t, value)

var target []S
arr.Decode(&target)

func (*Array) Every added in v2.12.0 

func (a *Array) Every(fn func(index int, value *Value)) *Array

Every runs the passed function on all the elements in the array.

If assertion inside function fails, the original Array is marked failed.

Every will execute the function for all values in the array irrespective of assertion failures for some values in the array.

Example: 

array := NewArray(t, []interface{}{"foo", "bar"})

array.Every(func(index int, value *httpexpect.Value) {
	value.String().NotEmpty()
})

func (*Array) Filter added in v2.12.0 

func (a *Array) Filter(fn func(index int, value *Value) bool) *Array

Filter accepts a function that returns a boolean. The function is ran over the array elements. If the function returns true, the element passes the filter and is added to the new array of filtered elements. If false, the element is skipped (or in other words filtered out). After iterating through all the elements of the original array, the new filtered array is returned.

If there are any failed assertions in the filtering function, the element is omitted without causing test failure.

Example: 

array := NewArray(t, []interface{}{1, 2, "foo", "bar"})
filteredArray := array.Filter(func(index int, value *httpexpect.Value) bool {
	value.String().NotEmpty()		//fails on 1 and 2
	return value.Raw() != "bar"		//fails on "bar"
})
filteredArray.IsEqual([]interface{}{"foo"})	//succeeds

func (*Array) Find added in v2.12.0 

func (a *Array) Find(fn func(index int, value *Value) bool) *Value

Find accepts a function that returns a boolean, runs it over the array elements, and returns the first element on which it returned true.

If there are any failed assertions in the predicate function, the element is skipped without causing test failure.

If no elements were found, a failure is reported.

Example: 

array := NewArray(t, []interface{}{1, "foo", 101, "bar", 201})
foundValue := array.Find(func(index int, value *httpexpect.Value) bool {
	num := value.Number()    // skip if element is not a number
	return num.Raw() > 100   // check element value
})
foundValue.IsEqual(101) // succeeds

func (*Array) FindAll added in v2.12.0 

func (a *Array) FindAll(fn func(index int, value *Value) bool) []*Value

FindAll accepts a function that returns a boolean, runs it over the array elements, and returns all the elements on which it returned true.

If there are any failed assertions in the predicate function, the element is skipped without causing test failure.

If no elements were found, empty slice is returned without reporting error.

Example: 

array := NewArray(t, []interface{}{1, "foo", 101, "bar", 201})
foundValues := array.FindAll(func(index int, value *httpexpect.Value) bool {
	num := value.Number()   // skip if element is not a number
	return num.Raw() > 100  // check element value
})

assert.Equal(t, len(foundValues), 2)
foundValues[0].IsEqual(101)
foundValues[1].IsEqual(201)

array := NewArray(t, []interface{}{"foo", "123"})
array.HasValue(1, 123)

func (*Array) InList added in v2.12.0 

func (a *Array) InList(values ...interface{}) *Array

func (a *Array) IsOrdered(less ...func(x, y *Value) bool) *Array

IsOrdered succeeds if every element is not less than the previous element as defined on the given `less` comparator function. For default, it will use built-in comparator function for each data type. Built-in comparator requires all elements in the array to have same data type. Array with 0 or 1 element will always succeed

Example: 

array := NewArray(t, []interface{}{100, 101, 102})
array.IsOrdered() // succeeds
array.IsOrdered(func(x, y *httpexpect.Value) bool {
	return x.Number().Raw() < y.Number().Raw()
}) // succeeds

func (*Array) Iter 

func (a *Array) Iter() []Value

Iter returns a new slice of Values attached to array elements.

	// Name of the running test
	// Usually comes from testing.T
	TestName string

	// Name of request being sent
	// Comes from Request.WithName()
	RequestName string

	// Chain of nested assertion names
	// Example value:
	//   {`Request("GET")`, `Expect()`, `JSON()`, `NotNull()`}
	Path []string

	// Chain of nested assertion names starting from alias
	// When alias is not set, AliasedPath has the same value as Path
	// Example value:
	//   {`foo`, `NotNull()`} // alias named foo
	AliasedPath []string

	// Request being sent
	// May be nil if request was not yet sent
	Request *Request

	// Response being matched
	// May be nil if response was not yet received

	// Environment shared between tests
	// Comes from Expect instance
	Environment *Environment

	// Whether reporter is known to output to testing.TB
	// For example, true when reporter is testing.T or testify-based reporter.
	TestingTB bool
}

AssertionContext provides context where the assetion happened.

type AssertionFailure added in v2.12.0 

type AssertionFailure struct {
	// Type of failed assertion
	Type AssertionType

	// Severity of failure
	Severity AssertionSeverity

	// Deprecated: use Severity
	IsFatal bool

	// List of error messages
	Errors []error

	// Actually observed value
	Actual *AssertionValue

	// Expected value
	Expected *AssertionValue

	// Reference value
	Reference *AssertionValue

	// Allowed delta between actual and expected
	Delta *AssertionValue

	// Stacktrace of the failure
	Stacktrace []StacktraceEntry
}

AssertionFailure provides detailed information about failed assertion.

[Type] and [Errors] fields are set for all assertions. [Actual], [Expected], [Reference], and [Delta] fields are set only for certain assertion types.

The value itself is stored in [Actual.Value], [Expected.Value], etc. It allows to distinguish whether the value is not present at all, or is present but is nil.

[Actual] stores the value being examined.

Exact meaning of [Expected] depends on assertion type. It may be the value to which [Actual] was compared, or range to which [Actual] should belong, or pattern with which [Actual] should match, or element which [Actual] should contain, and so on.

If [Reference] is set, it stores the value from which the check originated. For example, the user asked to check for unordered equality of arrays A and B. During comparison, a check failed that array A contains element E from array B. In this case [Actual] will be set to A (actually observed array), [Expected] will be set to E (expected but missing element), and [Reference] will be set to B (reference array that originated the check).

If [Delta] is set, it stores maximum allowed difference between [Actual] and [Expected] values.

For further details, see comments for corresponding AssertionType constant.

type AssertionHandler added in v2.12.0 

type AssertionHandler interface {
	// Invoked every time when an assertion succeeded.
	// May ignore failure, or log it, e.g. using t.Logf().
	Success(*AssertionContext)

	// Invoked every time when an assertion failed.
	// Handling depends on Failure.Severity field:
	//  - for SeverityError, reports failure to testing suite, e.g. using t.Errorf()
	//  - for SeverityLog, ignores failure, or logs it, e.g. using t.Logf()
	Failure(*AssertionContext, *AssertionFailure)
}

AssertionHandler takes care of formatting and reporting test Failure or Success.

You can log every performed assertion, or report only failures. You can implement custom formatting, for example, provide a JSON output for ulterior processing.

Usually you don't need to implement AssertionHandler; instead you can implement Reporter, which is much simpler, and use it with DefaultAssertionHandler.

const (
	// This assertion failure should mark current test as failed.
	// Typically handler will call t.Errorf().
	// This severity is used for most assertions.
	SeverityError AssertionSeverity = iota

	// This assertion failure is informational only, it can be logged,
	// but should not cause test failure.
	// Typically handler will call t.Logf(), or just ignore assertion.
	// This severity is used for assertions issued inside predicate functions,
	// e.g. in Array.Filter and Object.Filter.

	FailureTemplate string

	// When SuccessTemplate or FailureTemplate is set, this field
	// defines the function map passed to template engine.
	// May be nil.
	TemplateFuncs template.FuncMap
}

DefaultFormatter is the default Formatter implementation.

DefaultFormatter gathers values from AssertionContext and AssertionFailure, converts them to strings, and creates FormatData struct. Then it passes FormatData to the template engine (text/template) to format message.

You can control what is included and what is excluded from messages via several public fields.

If desired, you can provide custom templates and function map. This may be easier than creating your own formatter from scratch.

Reporter is used to report failures. *testing.T, FatalReporter, AssertReporter, RequireReporter, PanicReporter implement it.

type ReporterFunc added in v2.15.1 

type ReporterFunc func(message string, args ...interface{})

ReporterFunc is an adapter that allows a function to be used as the Reporter

Example: 

e := httpexpect.WithConfig(httpexpect.Config{
	Reporter: httpextect.ReporterFunc(
		func(message string, args ...interface{}) {
			// reporter code here
		}),
})

func (ReporterFunc) Errorf added in v2.15.1 

func (f ReporterFunc) Errorf(message string, args ...interface{})

type Request 

type Request struct {
	// contains filtered or unexported fields
}

Request provides methods to incrementally build http.Request object, send it, and receive response.

func NewRequest deprecated 

func NewRequest(config Config, method, path string, pathargs ...interface{}) *Request

Deprecated: use NewRequestC instead.

func NewRequestC added in v2.12.0 

func NewRequestC(config Config, method, path string, pathargs ...interface{}) *Request

NewRequestC returns a new Request instance.

Requirements for config are same as for WithConfig function.

method defines the HTTP method (GET, POST, PUT, etc.). path defines url path.

Simple interpolation is allowed for {named} parameters in path:

  • if pathargs is given, it's used to substitute first len(pathargs) parameters, regardless of their names
  • if WithPath() or WithPathObject() is called, it's used to substitute given parameters by name

For example: 

req := NewRequestC(config, "POST", "/repos/{user}/{repo}", "iris-contrib", "httpexpect")
// path will be "/repos/iris-contrib/httpexpect"

Or: 

req := NewRequestC(config, "POST", "/repos/{user}/{repo}")
req.WithPath("user", "iris-contrib")
req.WithPath("repo", "httpexpect")
// path will be "/repos/iris-contrib/httpexpect"

After interpolation, path is urlencoded and appended to Config.BaseURL, separated by slash. If BaseURL ends with a slash and path (after interpolation) starts with a slash, only single slash is inserted.

func (*Request) Alias added in v2.12.0 

func (r *Request) Alias(name string) *Request

Alias is similar to Value.Alias.

func (*Request) Expect 

func (r *Request) Expect() *Response

Expect constructs http.Request, sends it, receives http.Response, and returns a new Response instance.

Request is sent using Client interface, or WebsocketDialer in case of WebSocket request.

After calling Expect, there should not be any more calls of Expect or other WithXXX methods on the same Request instance.

Example: 

req := NewRequestC(config, "PUT", "http://example.com/path")
req.WithJSON(map[string]interface{}{"foo": 123})
resp := req.Expect()
resp.Status(http.StatusOK)

func (*Request) WithAssertionHandler added in v2.15.1 

func (r *Request) WithAssertionHandler(handler AssertionHandler) *Request

WithAssertionHandler sets assertion handler to be used for this request.

The new handler overwrites assertion handler that will be used by Request and its children (Response, Body, etc.). It will be used to format and report test Failure or Success.

Example: 

req := NewRequestC(config, "GET", "http://example.com/path")
req.WithAssertionHandler(&DefaultAssertionHandler{
	Reporter:  reporter,
	Formatter: formatter,
})

func (*Request) WithBasicAuth 

func (r *Request) WithBasicAuth(username, password string) *Request

WithBasicAuth sets the request's Authorization header to use HTTP Basic Authentication with the provided username and password.

Example: 

req := NewRequestC(config, "PUT", "http://example.com/path")
req.WithBasicAuth("john", "secret")

func (*Request) WithBytes 

func (r *Request) WithBytes(b []byte) *Request

req.WithBytes([]byte(`{"foo": 123}`))

func (*Request) WithChunked 

func (r *Request) WithChunked(reader io.Reader) *Request

WithChunked enables chunked encoding and sets request body reader.

Expect() will read all available data from given reader. Content-Length is not set, and "chunked" Transfer-Encoding is used.

If protocol version is not at least HTTP/1.1 (required for chunked encoding), failure is reported.

Example: 

req := NewRequestC(config, "PUT", "http://example.com/upload")
fh, _ := os.Open("data")
defer fh.Close()
req.WithHeader("Content-Type", "application/octet-stream")
req.WithChunked(fh)

func (*Request) WithClient 

func (r *Request) WithClient(client Client) *Request

WithClient sets client.

The new client overwrites Config.Client. It will be used once to send the request and receive a response.

req.WithClient(&http.Client{
  Transport: &http.Transport{
	DisableCompression: true,
  },
})

func (*Request) WithContext added in v2.3.1 

func (r *Request) WithContext(ctx context.Context) *Request

WithContext sets the context.

Config.Context will be overwritten.

Any retries will stop after one is cancelled. If the intended behavior is to continue any further retries, use WithTimeout.

Example: 

ctx, _ = context.WithTimeout(context.Background(), time.Duration(3)*time.Second)
req := NewRequestC(config, "GET", "/path")
req.WithContext(ctx)
req.Expect().Status(http.StatusOK)

	"foo": "aa",
	"bar": "bb",
})

func (*Request) WithFile 

func (r *Request) WithFile(key, path string, reader ...io.Reader) *Request

WithFile sets Content-Type header to "multipart/form-data", reads given file and adds its contents to request body.

If reader is given, it's used to read file contents. Otherwise, os.Open() is used to read a file with given path.

Multiple WithForm(), WithFormField(), and WithFile() calls may be combined. WithMultipart() should be called before WithFile(), otherwise WithFile() fails.

Example: 

req := NewRequestC(config, "PUT", "http://example.com/path")
req.WithFile("avatar", "./john.png")

req := NewRequestC(config, "PUT", "http://example.com/path")
fh, _ := os.Open("./john.png")
req.WithMultipart().
	WithFile("avatar", "john.png", fh)
fh.Close()

func (*Request) WithFileBytes 

func (r *Request) WithFileBytes(key, path string, data []byte) *Request

Example: 

req := NewRequestC(config, "PUT", "http://example.com/path")
fh, _ := os.Open("./john.png")
b, _ := ioutil.ReadAll(fh)
req.WithMultipart().
	WithFileBytes("avatar", "john.png", b)
fh.Close()

func (*Request) WithForm 

func (r *Request) WithForm(object interface{}) *Request

WithForm sets Content-Type header to "application/x-www-form-urlencoded" or (if WithMultipart() was called) "multipart/form-data", converts given object to url.Values using github.com/ajg/form, and adds it to request body.

Various object types are supported, including maps and structs. Structs may contain "form" struct tag, similar to "json" struct tag for json.Marshal(). See https://github.com/ajg/form for details.

Multiple WithForm(), WithFormField(), and WithFile() calls may be combined. If WithMultipart() is called, it should be called first.

Example: 

type MyForm struct {
	Foo int `form:"foo"`
}

req := NewRequestC(config, "PUT", "http://example.com/path")
req.WithForm(MyForm{Foo: 123})

req := NewRequestC(config, "PUT", "http://example.com/path")
req.WithForm(map[string]interface{}{"foo": 123})

func (*Request) WithFormField 

func (r *Request) WithFormField(key string, value interface{}) *Request

WithFormField sets Content-Type header to "application/x-www-form-urlencoded" or (if WithMultipart() was called) "multipart/form-data", converts given value to string using fmt.Sprint(), and adds it to request body.

Multiple WithForm(), WithFormField(), and WithFile() calls may be combined. If WithMultipart() is called, it should be called first.

Example: 

req := NewRequestC(config, "PUT", "http://example.com/path")
req.WithFormField("foo", 123).
	WithFormField("bar", 456)

func (*Request) WithHandler 

func (r *Request) WithHandler(handler http.Handler) *Request

WithHandler configures client to invoke the given handler directly.

If Config.Client is http.Client, then only its Transport field is overwritten because the client may contain some state shared among requests like a cookie jar. Otherwise, the whole client is overwritten with a new client.

Example: 

req := NewRequestC(config, "GET", "/path")
req.WithHandler(myServer.someHandler)

func (*Request) WithHeader 

func (r *Request) WithHeader(k, v string) *Request

WithHeader adds given single header to request.

req.WithHeader("Content-Type", "application/json")

func (*Request) WithHeaders 

func (r *Request) WithHeaders(headers map[string]string) *Request

WithHeaders adds given headers to request.

Example: 

req := NewRequestC(config, "PUT", "http://example.com/path")
req.WithHeaders(map[string]string{
	"Content-Type": "application/json",
})

func (*Request) WithHost added in v2.3.1

req.WithJSON(map[string]interface{}{"foo": 123})

func (*Request) WithMatcher 

func (r *Request) WithMatcher(matcher func(*Response)) *Request

WithMatcher attaches a matcher to the request. All attached matchers are invoked in the Expect method for a newly created Response.

Example: 

req := NewRequestC(config, "GET", "/path")
req.WithMatcher(func (resp *httpexpect.Response) {
	resp.Header("API-Version").NotEmpty()
})

func (*Request) WithMaxRedirects added in v2.3.1 

func (r *Request) WithMaxRedirects(maxRedirects int) *Request

WithMaxRedirects sets maximum number of redirects to follow.

If the number of redirects exceedes this limit, request is failed.

Default limit is defined by Client implementation. Default behavior of http.Client corresponds to maximum of 10-1 redirects.

This method can be used only if Client interface points to *http.Client struct, since we rely on it in redirect handling.

Example: 

req1 := NewRequestC(config, "POST", "/path")
req1.WithMaxRedirects(1)
req1.Expect().Status(http.StatusOK)

func (*Request) WithMaxRetries added in v2.3.1 

func (r *Request) WithMaxRetries(maxRetries int) *Request

WithMaxRetries sets maximum number of retry attempts.

After first request failure, additional retry attempts may happen, depending on the retry policy.

Setting this to zero disables retries, i.e. only one request is sent. Setting this to N enables retries, and up to N+1 requests may be sent.

Default number of retries is zero, i.e. retries are disabled.

Example: 

req := NewRequestC(config, "POST", "/path")
req.WithMaxRetries(1)
req.Expect().Status(http.StatusOK)

func (*Request) WithMultipart 

func (r *Request) WithMultipart() *Request

WithMultipart sets Content-Type header to "multipart/form-data".

After this call, WithForm() and WithFormField() switch to multipart form instead of urlencoded form.

If WithMultipart() is called, it should be called before WithForm(), WithFormField(), and WithFile().

WithFile() always requires WithMultipart() to be called first.

Example: 

req := NewRequestC(config, "PUT", "http://example.com/path")
req.WithMultipart().
	WithForm(map[string]interface{}{"foo": 123})

func (*Request) WithName added in v2.12.0 

func (r *Request) WithName(name string) *Request

req.WithName("Login Request")

func (*Request) WithPath 

func (r *Request) WithPath(key string, value interface{}) *Request

WithPath substitutes named parameters in url path.

value is converted to string using fmt.Sprint(). If there is no named parameter '{key}' in url path, failure is reported.

Named parameters are case-insensitive.

Example: 

req := NewRequestC(config, "POST", "/repos/{user}/{repo}")
req.WithPath("user", "iris-contrib")
req.WithPath("repo", "httpexpect")
// path will be "/repos/iris-contrib/httpexpect"

func (*Request) WithPathObject 

func (r *Request) WithPathObject(object interface{}) *Request

WithPathObject substitutes multiple named parameters in url path.

object should be map or struct. If object is struct, it's converted to map using https://github.com/fatih/structs. Structs may contain "path" struct tag, similar to "json" struct tag for json.Marshal().

Each map value is converted to string using fmt.Sprint(). If there is no named parameter for some map '{key}' in url path, failure is reported.

Named parameters are case-insensitive.

Example: 

type MyPath struct {
	Login string `path:"user"`
	Repo  string
}

req := NewRequestC(config, "POST", "/repos/{user}/{repo}")
req.WithPathObject(MyPath{"iris-contrib", "httpexpect"})
// path will be "/repos/iris-contrib/httpexpect"

req := NewRequestC(config, "POST", "/repos/{user}/{repo}")
req.WithPathObject(map[string]string{"user": "iris-contrib", "repo": "httpexpect"})
// path will be "/repos/iris-contrib/httpexpect"

func (*Request) WithProto 

func (r *Request) WithProto(proto string) *Request

req.WithQuery("b", "foo")
// URL is now http://example.com/path?a=123&b=foo

func (*Request) WithQueryObject 

func (r *Request) WithQueryObject(object interface{}) *Request

WithQueryObject adds multiple query parameters to request URL.

object is converted to query string using github.com/google/go-querystring if it's a struct or pointer to struct, or github.com/ajg/form otherwise.

Various object types are supported. Structs may contain "url" struct tag, similar to "json" struct tag for json.Marshal().

Example: 

type MyURL struct {
	A int    `url:"a"`
	B string `url:"b"`
}

req := NewRequestC(config, "PUT", "http://example.com/path")
req.WithQueryObject(MyURL{A: 123, B: "foo"})
// URL is now http://example.com/path?a=123&b=foo

req := NewRequestC(config, "PUT", "http://example.com/path")

req.WithQueryString("b=22&c=33")
// URL is now http://example.com/path?a=11&bb=22&c=33

func (*Request) WithRedirectPolicy added in v2.3.1 

func (r *Request) WithRedirectPolicy(policy RedirectPolicy) *Request

WithRedirectPolicy sets policy for redirection response handling.

How redirect is handled depends on both response status code and redirect policy. See comments for RedirectPolicy for details.

Default redirect policy is defined by Client implementation. Default behavior of http.Client corresponds to FollowRedirectsWithoutBody.

This method can be used only if Client interface points to *http.Client struct, since we rely on it in redirect handling.

Example: 

req1 := NewRequestC(config, "POST", "/path")
req1.WithRedirectPolicy(FollowAllRedirects)
req1.Expect().Status(http.StatusOK)

req2 := NewRequestC(config, "POST", "/path")

req.WithReporter(t)

func (*Request) WithRetryDelay added in v2.3.1 

func (r *Request) WithRetryDelay(minDelay, maxDelay time.Duration) *Request

WithRetryDelay sets minimum and maximum delay between retries.

If multiple retry attempts happen, delay between attempts starts from minDelay and then grows exponentionally until it reaches maxDelay.

Default delay range is [50ms; 5s].

Example: 

req := NewRequestC(config, "POST", "/path")
req.WithRetryDelay(time.Second, time.Minute)
req.Expect().Status(http.StatusOK)

func (*Request) WithRetryPolicy added in v2.3.1 

func (r *Request) WithRetryPolicy(policy RetryPolicy) *Request

WithRetryPolicy sets policy for retries.

Whether a request is retried depends on error type (if any), response status code (if any), and retry policy.

How much retry attempts happens is defined by WithMaxRetries(). How much to wait between attempts is defined by WithRetryDelay().

Default retry policy is RetryTimeoutAndServerErrors, but default maximum number of retries is zero, so no retries happen unless WithMaxRetries() is called.

Example: 

req := NewRequestC(config, "POST", "/path")
req.WithRetryPolicy(RetryAllErrors)
req.Expect().Status(http.StatusOK)

func (*Request) WithText

Any retries will continue after one is cancelled. If the intended behavior is to stop any further retries, use WithContext or Config.Context.

Example: 

req := NewRequestC(config, "GET", "/path")
req.WithTimeout(time.Duration(3)*time.Second)
req.Expect().Status(http.StatusOK)

func (*Request) WithTransformer added in v2.3.1

req.WithTransformer(func(r *http.Request) { r.Header.Add("foo", "bar") })

func (*Request) WithURL 

func (r *Request) WithURL(urlStr string) *Request

WithURL sets request URL.

This URL overwrites Config.BaseURL. Request path passed to request constructor is appended to this URL, separated by slash if necessary.

req := NewRequestC(config, "PUT", "/path")
req.WithURL("http://example.com")
// URL is now http://example.com/path

func (*Request) WithWebsocketDialer 

func (r *Request) WithWebsocketDialer(dialer WebsocketDialer) *Request

WithWebsocketDialer sets the custom websocket dialer.

The new dialer overwrites Config.WebsocketDialer. It will be used once to establish the WebSocket connection and receive a response of handshake result.

Example: 

req := NewRequestC(config, "GET", "/path")
req.WithWebsocketUpgrade()
req.WithWebsocketDialer(&websocket.Dialer{
  EnableCompression: false,
})
ws := req.Expect().Status(http.StatusSwitchingProtocols).Websocket()
defer ws.Disconnect()

func (*Request) WithWebsocketUpgrade 

func (r *Request) WithWebsocketUpgrade() *Request

WithWebsocketUpgrade enables upgrades the connection to websocket.

At least the following fields are added to the request header: 

Upgrade: websocket
Connection: Upgrade

The actual set of header fields is define by the protocol implementation in the gorilla/websocket package.

The user should then call the Response.Websocket() method which returns the Websocket instance. This instance can be used to send messages to the server, to inspect the received messages, and to close the websocket.

Example: 

req := NewRequestC(config, "GET", "/path")
req.WithWebsocketUpgrade()
ws := req.Expect().Status(http.StatusSwitchingProtocols).Websocket()
defer ws.Disconnect()

Object returns a new Object attached to underlying value.

If underlying value is not an object (map[string]interface{}), failure is reported and empty (but non-nil) value is returned.

Example: 

value := NewValue(t, map[string]interface{}{"foo": 123})
value.Object().ContainsKey("foo")

func (*Value) Path 

func (v *Value) Path(path string) *Value

Path returns a new Value object for child object(s) matching given JSONPath expression.

JSONPath is a simple XPath-like query language. See http://goessner.net/articles/JsonPath/.

We currently use https://github.com/yalp/jsonpath, which implements only a subset of JSONPath, yet useful for simple queries. It doesn't support filters and requires double quotes for strings.

Example 1: 

json := `{"users": [{"name": "john"}, {"name": "bob"}]}`
value := NewValue(t, json)

value.Path("$.users[0].name").String().IsEqual("john")
value.Path("$.users[1].name").String().IsEqual("bob")

Example 2: 

json := `{"yfGH2a": {"user": "john"}, "f7GsDd": {"user": "john"}}`
value := NewValue(t, json)

for _, user := range value.Path("$..user").Array().Iter() {
	user.String().IsEqual("john")
}

func (*Value) Raw 

func (v *Value) Raw() interface{}

Raw returns underlying value attached to Value. This is the value originally passed to NewValue, converted to canonical form.

Example: 

value := NewValue(t, "foo")
assert.Equal(t, "foo", number.Raw().(string))

func (*Value) Schema 

func (v *Value) Schema(schema interface{}) *Value

Schema succeeds if value matches given JSON Schema.

JSON Schema specifies a JSON-based format to define the structure of JSON data. See http://json-schema.org/. We use https://github.com/xeipuuv/gojsonschema implementation.

schema should be one of the following:

  • go value that can be json.Marshal-ed to a valid schema
  • type convertible to string containing valid schema
  • type convertible to string containing valid http:// or file:// URI, pointing to reachable and valid schema

Example 1: 

 schema := `{
   "type": "object",
   "properties": {
	  "foo": {
		  "type": "string"
	  },
	  "bar": {
		  "type": "integer"
	  }
  },
  "require": ["foo", "bar"]
}`

value := NewValue(t, map[string]interface{}{
	"foo": "a",
	"bar": 1,
})

value.Schema(schema)

Example 2: 

value := NewValue(t, data)
value.Schema("http://example.com/schema.json")

func (*Value) String 

func (v *Value) String() *String

String returns a new String attached to underlying value.

If underlying value is not a string, failure is reported and empty (but non-nil) value is returned.

Example: 

value := NewValue(t, "foo")
value.String().IsEqualFold("FOO")
