Functions

func DumpRequest

func DumpRequest(req *http.Request) ([]byte, error)

DumpRequest returns a string representation of an HTTP request, automatically pretty printing JSON bodies for readability.

func DumpResponse

func DumpResponse(resp *http.Response) ([]byte, error)

DumpResponse returns a string representation of an HTTP response, automatically pretty printing JSON bodies for readability.

func NewAdapter

func NewAdapter() huma.Adapter

NewAdapter creates a new test adapter from a router.

func NewContext

func NewContext(op *huma.Operation, r *http.Request, w http.ResponseWriter) huma.Context

NewContext creates a new test context from an HTTP request and response.

func PrintRequest

func PrintRequest(req *http.Request)

PrintRequest prints a string representation of an HTTP request to stdout, automatically pretty printing JSON bodies for readability.

Example

req, _ := http.NewRequest(http.MethodGet, "http://example.com/foo?bar=baz", nil)
req.Header.Set("Foo", "bar")
req.Host = "example.com"
PrintRequest(req)

Output:

GET /foo?bar=baz HTTP/1.1
Host: example.com
Foo: bar

func PrintResponse

func PrintResponse(resp *http.Response)

PrintResponse prints a string representation of an HTTP response to stdout, automatically pretty printing JSON bodies for readability.

Example

resp := &http.Response{
	StatusCode: http.StatusOK,
	ProtoMajor: 1,
	ProtoMinor: 1,
	Header: http.Header{
		"Content-Type": []string{"application/json"},
	},
	ContentLength: -1,
	Body:          io.NopCloser(strings.NewReader(`{"foo": "bar"}`)),
}
PrintResponse(resp)

Output:

HTTP/1.1 200 OK
Connection: close
Content-Type: application/json

{
  "foo": "bar"
}

Types

type TB

type TB interface {
	Helper()
	Log(args ...any)
	Logf(format string, args ...any)
}

TB is a subset of the `testing.TB` interface used by the test API and implemented by the `*testing.T` and `*testing.B` structs.

TestAPI is a `huma.API` with additional methods specifically for testing.

func New

func New(tb TB, configs ...huma.Config) (http.Handler, TestAPI)

New creates a new router and test API, making it easy to register operations and perform requests against them. Optionally takes a configuration object to customize how the API is created. If no configuration is provided then a simple default configuration supporting `application/json` is used.

func Wrap

func Wrap(tb TB, api huma.API) TestAPI

Wrap returns a `TestAPI` wrapping the given API.
