使用 Moq 确定方法是否被调用 [英] Using Moq to determine if a method is called
本文介绍了使用 Moq 确定方法是否被调用的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
据我所知,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.
我认为在模拟框架中可以使用这种测试是否正确?
Am I right in thinking this sort of test is available in a mocking framework?
推荐答案
你可以通过验证查看你模拟的某个方法是否被调用过,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,当您调用验证时它将抛出 MockException.如果没有注释它就会通过.
If the line is left commented it will throw a MockException when you call Verify. If it is uncommented it will pass.
