我正在尝试使用stretchr/testify对如下代码进行单元测试:

func (c *MyClient) upsertData(data MyObject) {
    upsertToDatabase(data)
}

func doSomething(c *MyClient) {
    data1, data2 := getSomeData()
    c.upsertToDatabase(data1)
    c.upsertToDatabase(data2)
}

// Unit test.
func TestDoSomething(t *testing.T) {
    c := mock.MyClient{}
    doSomething(c)
    /* The following line checking for data1 upsert failed.
     * require.True(t, c.AssertCalled(t, "upsertToDatabase", mock.MatchedBy(func(data MyObject) bool { return data == MyObject{expectedObject1 /* data2 */}})) */
    require.True(t, c.AssertCalled(t, "upsertToDatabase", mock.MatchedBy(func(data MyObject) bool { return data == MyObject{expectedObject1 /* data2 */}}))
}

我想调用并AssertCalled验证两者确实是用预期的函数调用的。但是我只能在函数的最后一次调用中断言,即使用. 有什么方法或我可以用它来断言调用吗?data1data2data2data1

文档中的示例:

/*
  Actual test functions
*/

// TestSomething is an example of how to use our test object to
// make assertions about some target code we are testing.
func TestSomething(t *testing.T) {

  // create an instance of our test object
  testObj := new(MyMockedObject)

  // setup expectations
  testObj.On("DoSomething", 123).Return(true, nil)

  // call the code we are testing
  targetFuncThatDoesSomethingWithObj(testObj)

  // assert that the expectations were met
  testObj.AssertExpectations(t)


}

看起来您可以调用.On任意次数来记录任意数量的“以这种方式和这种方式调用”的期望。

我只是阅读源代码,真的。打赌它会比在 SO 上发帖更快。
