验证使用 Moq 调用受保护方法的次数

问题描述

在我的单元测试中，我正在使用 Moq 模拟一个受保护的方法，并且想断言它被调用了一定次数.这个问题描述了与早期版本的 Moq 类似的内容:

In my unit-tests I'm mocking a protected method using Moq, and would like to assert that it is called a certain number of times. This question describes something similar for an earlier version of Moq:

//expect that ChildMethod1() will be called once. (it's protected)
testBaseMock.Protected().Expect("ChildMethod1")
  .AtMostOnce()
  .Verifiable();

...
testBase.Verify();

但这不再有效；从那时起语法发生了变化，我找不到使用 Moq 4.x 的新等效项:

but this no longer works; the syntax has changed since then and I cannot find the new equivalent using Moq 4.x:

testBaseMock.Protected().Setup("ChildMethod1")
  // no AtMostOnce() or related method anymore
  .Verifiable();

...
testBase.Verify();

推荐答案

在 Moq.Protected 命名空间，有一个 IProtectedMock 接口，具有以 Times 作为参数的 Verify 方法.

In the Moq.Protected namespace, there is an IProtectedMock interface that has a Verify method taking Times as a parameter.

编辑这至少从最小起订量 4.0.10827 开始可用.语法示例:

Edit This is available since at least Moq 4.0.10827. Syntax example:

testBaseMock.Protected().Setup("ChildMethod1");

...
testBaseMock.Protected().Verify("ChildMethod1", Times.Once());
