我对c#中的单元测试和学习使用Moq还是个新手。下面是我要测试的类。
class MyClass
{
SomeClass someClass;
public MyClass(SomeClass someClass)
{
this.someClass = someClass;
}
public void MyMethod(string method)
{
method = "test"
someClass.DoSomething(method);
}
}
class Someclass
{
public DoSomething(string method)
{
// do something...
}
}
下面是我的TestClass:
class MyClassTest
{
[TestMethod()]
public void MyMethodTest()
{
string action="test";
Mock<SomeClass> mockSomeClass = new Mock<SomeClass>();
mockSomeClass.SetUp(a => a.DoSomething(action));
MyClass myClass = new MyClass(mockSomeClass.Object);
myClass.MyMethod(action);
mockSomeClass.Verify(v => v.DoSomething(It.IsAny<string>()));
}
}
我得到以下异常:
Expected invocation on the mock at least once, but was never performed
No setups configured.
No invocations performed..
我只想验证方法MyMethod是否被调用。我遗漏了什么吗?
你用错方法了。Moq要求您在依赖类中设置(然后可选地验证)方法。
你应该这样做:
class MyClassTest
{
[TestMethod]
public void MyMethodTest()
{
string action = "test";
Mock<SomeClass> mockSomeClass = new Mock<SomeClass>();
mockSomeClass.Setup(mock => mock.DoSomething());
MyClass myClass = new MyClass(mockSomeClass.Object);
myClass.MyMethod(action);
// Explicitly verify each expectation...
mockSomeClass.Verify(mock => mock.DoSomething(), Times.Once());
// ...or verify everything.
// mockSomeClass.VerifyAll();
}
}
换句话说，您正在验证调用myclass# MyMethod，您的类肯定会在该过程中调用SomeClass#DoSomething一次。注意，您不需要Times参数;我只是在证明它的价值。
