用PowerMockito在内部类中模拟final方法

Question

PowerMockito.when(connectionMock.authUser("fake-user", "fake-password")).thenReturn("random string");

@RunWith(PowerMockRunner.class)
@PrepareForTest({MyClass.class, APIClientConnection.class})
public class MyClassTest {
    @Test
    public void apiConnect() throws Exception {
        MyClass c = new MyClass();
        APIClientConnection connectionMock = PowerMockito.mock(APIClientConnection.class);
        PowerMockito.whenNew(APIClientConnection.class).withAnyArguments().thenReturn(connectionMock);
        PowerMockito.when(connectionMock.authUser("fake-user", "fake-password")).thenReturn("random string");
        c.apiConnect("fake-host", 80, "fake-user", "fake-password");
    }
}

public class MyClass {
    public MyClass() { }
    public APIClientConnection apiConnect(String host, int port, String user, String pass) {
            conn = new APIClientConnection(host, port);
            conn.authUser(user, pass);
    }
}

其中authUser（）定义为final,如下所示：

public class APIClientConnection {
    public final String authUser(String username, String password) {
        ...
    }
}

我正在学习如何使用PowerMock模拟非静态方法，以及Powermockito是否可以模拟非final具体类中的final方法？。我尝试了一些变体，例如使用Mockito而不是PowerMock来存根authUser，以及将apiclientconnection.class添加到PrepareForTest注释中。我不明白为什么它不起作用。我做错了什么？

Answer 1

你的问题就在这里

PowerMockito.when(connectionMock.authUser("user", "password")).thenReturn("random string");
c.apiConnect("fake-host", 80, "fake-user", "fake-password");

您指示，当用户使用凭据user/password登录时，应该停止该方法，但您发送的是fake-user/fake-password。

将最后一行替换为c.apiconnect（“fake-host”,80,“user”,“password”）；
