how to mock a void method in powermock
提问by user2831237
How to mock a void method which is non-static, non-finalThe signature of method is as below. I'm using Powermockito.
如何模拟一个非静态、非 final 的 void 方法方法的签名如下。我正在使用 Powermockito。
public class Name{
public void methodName{
...
...
}
}
@RunWith(PowerMockRunner.class)
@PrepareForTest({Name.class})
public class TestClass{
@Test
public void testMethodName(){
PowerMockito.doNothing().when(Name.class, methodName);
//some when calls after this and assert later on
}
I want to DO Nothing when methodName is called. the above code is not working. it says methodName cannot be resolved.
调用 methodName 时我什么都不做。上面的代码不起作用。它说 methodName 无法解析。

You can Use PowerMock.createmock() for Mocking your Class Where method is There. For e.g you have ClassA and methodA which is a Void Method. Then You can Mock it in a below way:
您可以使用 PowerMock.createmock() 来模拟您的类 Where 方法。例如，你有 ClassA 和 methodA，这是一个 Void 方法。然后你可以通过以下方式模拟它：
A a = PowerMock.CreateMock(A.class);
a.methodA();
PowerMock.replay(a);
Note : in above case method a is void That's the reason EasyMock.expect is not return;
注意：在上述情况下，方法 a 是无效的，这就是 EasyMock.expect 不返回的原因；

if you want to mock a non-static method you need to specify the mock object:
如果要模拟非静态方法，则需要指定模拟对象：
public class Name{
public void methodName{
...
}
}
@RunWith(PowerMockRunner.class)
@PrepareForTest({Name.class})
public class TestClass{
@Test
public void testMethodName(){
Name myName = PowerMockito.mock(Name.class);
PowerMockito.doNothing().when(myName).methodName();
//some when calls after this and assert later on
}
}

I'm not at an IDE at the moment, but I think you can do this:
我目前不在 IDE 中，但我认为您可以这样做：
final Name name = mock(Name.class);
doNothing().when(name).methodName();
