mocking - 模拟静态函数调用时出错

Question

我正在尝试模拟静态，但收到如下错误消息

org.mockito.exceptions.misusing.MissingMethodInvocationException: 
when() requires an argument which has to be 'a method call on a mock'.
For example:
    when(mock.getArticles()).thenReturn(articles);

我的测试类实现就像

@RunWith(SpringJUnit4ClassRunner.class)
@PrepareForTest(SponsorUtil.class)
@DirtiesContext(classMode = DirtiesContext.ClassMode.AFTER_CLASS)
@ContextConfiguration(locations = "classpath:/spring/spring-service.xml", loader=SpringockitoContextLoader.class, inheritLocations = false)
public class SponsorStaticTest {

  @Test
  public void testStaticMethod(){

    PowerMockito.mockStatic(SponsorUtil.class);
    PHistory pHistory = new PHistory();
    pHistory.setPersonId("123");
    Person person1 = new Person();
    Person person2 = new Person();
    PowerMockito.when(SponsorUtil.populatePersonDiff(person1,person2)).thenReturn(pHistory);
  }


}

我尝试了论坛上提供的很多方法，但还是遇到同样的问题。

我在这里缺少什么？

Answer 1

当您使用@RunWith(SpringJUnit4ClassRunner.class)时，静态模拟将不起作用。看起来你同时需要 powermocking 和 Spring 的东西。

看看 JUnit 委托(delegate)运行器:https://github.com/jayway/powermock/wiki/JUnit_Delegating_Runner 。使用委托(delegate)运行程序时，您指定 @RunWith(PowerMockRunner.class) ，就像您在使用 PowerMockito 时通常所做的那样，但随后您包括 @PowerMockRunnerDelegate(SpringJUnit4ClassRunner.class)以及。该功能自 PowerMockito 1.6 版本起可用。

如果您由于某种原因必须使用旧版本的 PowerMockito，其他人也遇到了同样的问题:issues while using @RunWith Annotation and powerMock 。答案 https://stackoverflow.com/a/12158794/4076102 中描述的解决方案，就是使用PowerMockRule。在本例中，您使用 SpringJUnit4ClassRunner 而不是 PowerMockRunner，并创建一个 PowerMockRule 字段，并使用 @Rule 进行注释。 (点击查看详细信息和示例。)
