我正在使用 gomock 生成一个业务层并模拟它的方法结果。到目前为止，我无法通过测试，这是说“想要”和“得到”的价值观不同
我将我的对象的 json 表示传递给 strings.NewReader 并且“Want”带有一个值“等于 { { ...”，这可能是问题所在。

编辑：
我做了@bigpigeon 提到的
func TestCreate(t *testing.T) {
ctrl := gomock.NewController(t)
defer ctrl.Finish()
b, err := json.Marshal(&mockProduct)
fmt.Println(err)
fmt.Println(string(b))
e = echo.New()
e.Validator = middlewares.NewCustomValidator()
rec = httptest.NewRecorder()
req = httptest.NewRequest(http.MethodPost, "/v1/foo/bar", strings.NewReader(string(b)))
req.Header.Set(echo.HeaderContentType, echo.MIMEApplicationJSON)
c = e.NewContext(req, rec)
mockHandler := mock_product.NewMockIHandler(ctrl)
mockHandler.EXPECT().Save(&mockProduct).Return(&mockProduct, nil)
controller := NewController(mockHandler)
controller.Create(c)
