使用 Moq 确定是否调用了方法

问题描述

据我了解，如果我调用更高级别的方法，我可以测试是否会发生方法调用，即:

It is my understanding that I can test that a method call will occur if I call a higher level method, i.e.:

public abstract class SomeClass()
{    
    public void SomeMehod()
    {
        SomeOtherMethod();
    }

    internal abstract void SomeOtherMethod();
}

我想测试一下，如果我调用 SomeMethod() 那么我希望 SomeOtherMethod() 会被调用.

I want to test that if I call SomeMethod() then I expect that SomeOtherMethod() will be called.

我认为这种测试可以在模拟框架中使用是否正确?

Am I right in thinking this sort of test is available in a mocking framework?

推荐答案

你可以通过Verify来查看你已经mock过的东西中的某个方法是否被调用了，例如:

You can see if a method in something you have mocked has been called by using Verify, e.g.:

static void Main(string[] args)
{
        Mock<ITest> mock = new Mock<ITest>();

        ClassBeingTested testedClass = new ClassBeingTested();
        testedClass.WorkMethod(mock.Object);

        mock.Verify(m => m.MethodToCheckIfCalled());
}

class ClassBeingTested
{
    public void WorkMethod(ITest test)
    {
        //test.MethodToCheckIfCalled();
    }
}

public interface ITest
{
    void MethodToCheckIfCalled();
}

如果该行被留下注释，它会在您调用验证时抛出 MockException.如果未注释，它将通过.

If the line is left commented it will throw a MockException when you call Verify. If it is uncommented it will pass.
