Mockito 不返回预期的字符串，而是返回模拟对象

Question

I am mocking InetAddress , When I am mocking this I am getting mocked object instead of my expected string

    InetAddress inetAddress = Mockito.mock(InetAddress.class);
    Mockito.when(inetAddress.getHostName()).thenReturn("test")
    System.out.printinetAddress.getHostName());

I think It should print test in a console but it is printing mocked object hashcode.

Answer 1

Mockito.when(inetAddress.getHostName()).thenReturn("test")

With this line, you are saying mockito that when I call the inetAddress.getHostName() return me "test". You have done this declaration however, you have not call this mocked method to see what happens,instead you are printing mockito object which refers to an address like all other objects do in java. To see results, after creation of mocking object you should:

System.out.println(inetAddress.getHostName());
