mock.AssertCalled() with deep equals

Logic

type HttpClient interface {
	Do(req *http.Request) (*http.Response, error)
}

type webappClient struct {
	httpClient HttpClient
	...
}

func (c *client) Logout(token string) {
	request, _ := http.NewRequest(http.MethodPost, "https://foo.bar/logout", nil)
	c.HTTPClient.Do(request)
	...
}

Test

func TestLogout(t *testing.T) {
    // given
    httpMock := &httpClientMock{}
    httpMock.On("Do", mock.Anything).Return(&http.Response{}, nil)
    webappClient := NewWebappClient()

    // when
    webappClient.Logout("testToken")

    // then
    request, _ := http.NewRequest(http.MethodPost, "https://foo.bar/logout", nil)
    httpMock.AssertCalled(t, "Do", *request)
}

var _ HttpClient = (*httpClientMock)(nil)

type httpClientMock struct {
	mock.Mock
}

func (mock *httpClientMock) Do(req *http.Request) (*http.Response, error) {
	mock.Called(*req) // invokes the mock with provided param. use * to see eventual diffs in log output of AssertCalled()
	return &http.Response{}, nil
}
