Golang TestHandler Examples

Example #1

func TestErrorHandlerGetsUsedOnError(t *testing.T) {

	responseWriter := new(http_test.TestResponseWriter)
	testRequest, _ := http.NewRequest("GET", "http://stretchr.org/goweb", nil)

	codecService := codecsservices.NewWebCodecService()
	handler := NewHttpHandler(codecService)

	errorHandler := new(handlers_test.TestHandler)
	handler.SetErrorHandler(errorHandler)

	errorHandler.On("Handle", mock.Anything).Return(false, nil)

	// make a handler throw an error
	var theError error = errors.New("Test error")
	handler.Map(func(c context.Context) error {
		return theError
	})

	handler.ServeHTTP(responseWriter, testRequest)

	if mock.AssertExpectationsForObjects(t, errorHandler.Mock) {

		// get the first context
		ctx := errorHandler.Calls[0].Arguments[0].(context.Context)

		// make sure the error data field was set
		assert.Equal(t, theError.Error(), ctx.Data().Get("error").Data().(HandlerError).Error(), "the error should be set in the data with the 'error' key")
