apitest

A simple and extensible behavioural testing library. Supports mocking external http calls and renders sequence diagrams on completion.

In behavioural tests the internal structure of the app is not known by the tests. Data is input to the system and the outputs are expected to meet certain conditions.

Credits

This library was influenced by the following software packages:

  • YatSpec for creating sequence diagrams from tests
  • MockMVC and superagent for the concept and behavioural testing approach
  • Gock for the approach to mocking HTTP services in Go
  • Baloo for API design
Code snippets
JSON body matcher
func TestApi(t *testing.T) {
	apitest.New().
		Handler(handler).
		Get("/user/1234").
		Expect(t).
		Body(`{"id": "1234", "name": "Tate"}`).
		Status(http.StatusCreated).
		End()
}
JSONPath

For asserting on parts of the response body JSONPath may be used. A separate module must be installed which provides these assertions - go get -u github.com/steinfletcher/apitest-jsonpath. This is packaged separately to keep this library dependency free.

Given the response is {"a": 12345, "b": [{"key": "c", "value": "result"}]}

func TestApi(t *testing.T) {
	apitest.New().
		Handler(handler).
		Get("/hello").
		Expect(t).
		Assert(jsonpath.Contains(`$.b[? @.key=="c"].value`, "result")).
		End()
}

and jsonpath.Equals checks for value equality

func TestApi(t *testing.T) {
	apitest.New(handler).
		Get("/hello").
		Expect(t).
		Assert(jsonpath.Equal(`$.a`, float64(12345))).
		End()
}
Custom assert functions
func TestApi(t *testing.T) {
	apitest.New().
		Handler(handler).
		Get("/hello").
		Expect(t).
		Assert(func(res *http.Response, req *http.Request) error {
			assert.Equal(t, http.StatusOK, res.StatusCode)
			return nil
		}).
		End()
}
Assert cookies
func TestApi(t *testing.T) {
	apitest.New().
		Handler(handler).
		Patch("/hello").
		Expect(t).
		Status(http.StatusOK).
		Cookies(apitest.Cookie"ABC").Value("12345")).
		CookiePresent("Session-Token").
		CookieNotPresent("XXX").
		Cookies(
			apitest.Cookie("ABC").Value("12345"),
			apitest.Cookie("DEF").Value("67890"),
		).
		End()
}
Assert headers
func TestApi(t *testing.T) {
	apitest.New().
		Handler(handler).
		Get("/hello").
		Expect(t).
		Status(http.StatusOK).
		Headers(map[string]string{"ABC": "12345"}).
		End()
}
Mocking external http calls
var getUser = apitest.NewMock().
	Get("/user/12345").
	RespondWith().
	Body(`{"name": "jon", "id": "1234"}`).
	Status(http.StatusOK).
	End()

var getPreferences = apitest.NewMock().
	Get("/preferences/12345").
	RespondWith().
	Body(`{"is_contactable": true}`).
	Status(http.StatusOK).
	End()

func TestApi(t *testing.T) {
	apitest.New().
		Mocks(getUser, getPreferences).
		Handler(handler).
		Get("/hello").
		Expect(t).
		Status(http.StatusOK).
		Body(`{"name": "jon", "id": "1234"}`).
		End()
}
Generating sequence diagrams from tests

func TestApi(t *testing.T) {
	apitest.New().
		Report(apitest.SequenceDiagram()).
		Mocks(getUser, getPreferences).
		Handler(handler).
		Get("/hello").
		Expect(t).
		Status(http.StatusOK).
		Body(`{"name": "jon", "id": "1234"}`).
		End()
}

It is possible to override the default storage location by passing the formatter instance Report(apitest.NewSequenceDiagramFormatter(".sequence-diagrams")). You can bring your own formatter too if you want to produce custom output. By default a sequence diagram is rendered on a html page. See the demo

Debugging http requests and responses generated by api test and any mocks
func TestApi(t *testing.T) {
	apitest.New().
		Debug().
		Handler(handler).
		Get("/hello").
		Expect(t).
		Status(http.StatusOK).
		End()
}
Provide basic auth in the request
func TestApi(t *testing.T) {
	apitest.New().
		Handler(handler).
		Get("/hello").
		BasicAuth("username", "password").
		Expect(t).
		Status(http.StatusOK).
		End()
}
Provide cookies in the request
func TestApi(t *testing.T) {
	apitest.New().
		Handler(handler).
		Get("/hello").
		Cookies(apitest.Cookie("ABC").Value("12345")).
		Expect(t).
		Status(http.StatusOK).
		End()
}
Provide headers in the request
func TestApi(t *testing.T) {
	apitest.New().
		Handler(handler).
		Delete("/hello").
		Headers(map[string]string{"My-Header": "12345"}).
		Expect(t).
		Status(http.StatusOK).
		End()
}
Provide query parameters in the request

Query, QueryParams and QueryCollection can all be used in combination

func TestApi(t *testing.T) {
	apitest.New().
		Handler(handler).
		Get("/hello").
		QueryParams(map[string]string{"a": "1", "b": "2"}).
		Query("c", "d").
		Expect(t).
		Status(http.StatusOK).
		End()
}

Providing {"a": {"b", "c", "d"} results in parameters encoded as a=b&a=c&a=d. QueryCollection can be used in combination with Query

func TestApi(t *testing.T) {
	apitest.New().
		Handler(handler).
		Get("/hello").
		QueryCollection(map[string][]string{"a": {"b", "c", "d"}}).
		Expect(t).
		Status(http.StatusOK).
		End()
}
Provide a url encoded form body in the request
func TestApi(t *testing.T) {
	apitest.New().
		Handler(handler).
		Post("/hello").
		FormData("a", "1").
		FormData("b", "2").
		FormData("b", "3").
		FormData("c", "4", "5", "6").
		Expect(t).
		Status(http.StatusOK).
		End()
}
Capture the request and response data
func TestApi(t *testing.T) {
	apitest.New().
		Observe(func(res *http.Response, req *http.Request, apiTest *apitest.APITest) {
			// do something with res and req
		}).
		Handler(handler).
		Get("/hello").
		Expect(t).
		Status(http.StatusOK).
		End()
}
Intercept the request

This is useful for mutating the request before it is sent to the system under test.

func TestApi(t *testing.T) {
	apitest.New().
		Handler(handler).
		Intercept(func(req *http.Request) {
			req.URL.RawQuery = "a[]=xxx&a[]=yyy"
		}).
		Get("/hello").
		Expect(t).
		Status(http.StatusOK).
		End()
}
