我的模拟参考之一在主要阶级中变为无效

Question

对于参考客户端模拟可以准备并在测试方法中使用，但是当涉及MyMethod时，

class MainClass {
    public void myMethod() {
        HttpConnector httpConnector = getHttpConnector(arg);
        CLoseableHttpClient client = httpConnector.getDefaults(input); // client returning null
    }

    private HttpConnector getHttpConnector(String arg) {
        return new HttpConnector(arg)
    }
}

进行null testClass，请为此提供帮助？

@RunWith(PowerMockRunner.class)
class MainClassTest {
    @InjectMocks
    @Spy
    MainClass mainclass;

    public void myMethodTest() {
        HttpConnector httpConnector = Mockito.mock(HttpConnector.class);
        CLoseableHttpClient client = Mockito.mock(CLoseableHttpClient.class);
        Mockito.when(httpConnector.getDefaults(input)).thenReturn(client); // client returning with mock value
        mainclass.myMethod();
    }
}

如果我错过了任何代码中的任何错误或任何错误，请对此

Answer 1

您可以将私有方法gethtpconnector存根，以返回模拟的httpConnector

尝试此

@Test
public void myMethodTest() {
  HttpConnector httpConnector = Mockito.mock(HttpConnector.class);
  CLoseableHttpClient client = Mockito.mock(CLoseableHttpClient.class);
  Mockito.when(httpConnector.getDefaults(anyString())).thenReturn(client); 
  PowerMockito.when(mainclass, "getHttpConnector").thenReturn(httpConnector);
  mainclass.myMethod();
}

操作，我建议使用最新版本的摩索哥，这是PowerMock的替代方法。
