Functions

func Assert

func Assert(tb TB, condition bool, format string, a ...interface{})

Assert fails the test if the condition is false.

func DirHash

func DirHash(t *testing.T, path string) []byte

DirHash returns a hash of all files attribites and their content within a directory.

func DirSize

func DirSize(t *testing.T, path string) int64

DirSize returns the size in bytes of all files in a directory.

func Equals

func Equals(tb TB, exp, act interface{}, msgAndArgs ...interface{})

Equals fails the test if exp is not equal to act.

func ErrorEqual

func ErrorEqual(left, right error) bool

ErrorEqual compares Go errors for equality.

func NewLogger

func NewLogger(t *testing.T) log.Logger

NewLogger returns a gokit compatible Logger which calls t.Log.

func NewRoundTripCheckRequest

func NewRoundTripCheckRequest(checkRequest func(*http.Request), theResponse *http.Response, theError error) http.RoundTripper

NewRoundTripCheckRequest creates a new instance of a type that implements http.RoundTripper, which before returning theResponse and theError, executes checkRequest against a http.Request.

func NotOk

func NotOk(tb TB, err error, a ...interface{})

NotOk fails the test if an err is nil.

func Ok

func Ok(tb TB, err error)

Ok fails the test if an err is not nil.

Types

type Closer

type Closer interface {
	// Close reaps the underlying directory and its children. The directory
	// could be deleted by its users already.
	Close()
}

Closer is the interface that wraps the Close method.

func NewCallbackCloser

func NewCallbackCloser(fn func()) Closer

NewCallbackCloser returns a Closer that calls the provided function upon closing.

type MockContext

type MockContext struct {
	Error  error
	DoneCh chan struct{}
}

A MockContext provides a simple stub implementation of a Context

func (*MockContext) Deadline

func (c *MockContext) Deadline() (deadline time.Time, ok bool)

Deadline always will return not set

func (*MockContext) Done

func (c *MockContext) Done() <-chan struct{}

Done returns a read channel for listening to the Done event

func (*MockContext) Err

func (c *MockContext) Err() error

Err returns the error, is nil if not set.

func (*MockContext) Value

func (c *MockContext) Value(key interface{}) interface{}

Value ignores the Value and always returns nil

type T

type T interface {
	Fatal(args ...interface{})
	Fatalf(format string, args ...interface{})
}

T implements the needed methods of testing.TB so that we do not need to actually import testing (which has the side effect of adding all the test flags, which we do not want in non-test binaries even if they make use of these utilities for some reason).

type TB

type TB interface {
	Helper()
	Fatalf(string, ...interface{})
}

This package is imported by non-test code and therefore cannot import the testing package, which has side effects such as adding flags. Hence we use an interface to testing.{T,B}.

type TemporaryDirectory

type TemporaryDirectory interface {
	Closer

	// Path returns the underlying path for access.
	Path() string
}

TemporaryDirectory models a closeable path for transient POSIX disk activities.

func NewTemporaryDirectory

func NewTemporaryDirectory(name string, t T) (handler TemporaryDirectory)

NewTemporaryDirectory creates a new temporary directory for transient POSIX activities.
