PowerMockRunner和ActiveObjectsJUnitRunner

Jira的二次开发，须要做单元测试。

测试跟数据库链接的类，好比service类，须要在类上加@RunWith(ActiveObjectsJUnitRunner.class).

有时须要搭配mockito使用，jira里好像是内置了mockito仍是怎么回事，不用再类上加@RunWith(MockitoJUnitRunner.class),也能够模拟类

可是当有须要模拟类的静态方法和私有方法时，mockito就使不上力了，这是须要导入PowerMock。可是@RunWith只能接收一个参数，并且也不能再类上使用两个@RunWith。

Using another JUnit Runner with PowerMock

里面有降到如何在使用PowerMockRunner，能够接着使用其余Runner，样例里是SpringJUnit4ClassRunner

 1 package org.powermock.examples.spring.mockito;
 2 
 3 import org.junit.Test;
 4 import org.junit.runner.RunWith;
 5 import org.powermock.core.classloader.annotations.PowerMockIgnore;
 6 import org.powermock.core.classloader.annotations.PrepareForTest;
 7 import org.powermock.modules.junit4.PowerMockRunner;
 8 import org.powermock.modules.junit4.PowerMockRunnerDelegate;
 9 import org.springframework.beans.factory.annotation.Autowired;
10 import org.springframework.test.context.ContextConfiguration;
11 import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
12 import powermock.examples.spring.IdGenerator;
13 import powermock.examples.spring.Message;
14 import powermock.examples.spring.MyBean;
15 
16 import static org.junit.Assert.assertEquals;
17 import static org.powermock.api.mockito.PowerMockito.*;
18 import static org.powermock.api.support.membermodification.MemberMatcher.method;
19 import static org.powermock.api.support.membermodification.MemberModifier.stub;
20 import static org.powermock.api.support.membermodification.MemberModifier.suppress;
21 
22 @RunWith(PowerMockRunner.class)
23 @PowerMockRunnerDelegate(SpringJUnit4ClassRunner.class)
24 @ContextConfiguration("classpath:/example-context.xml")
25 @PrepareForTest(IdGenerator.class)
26 public class SpringExampleTest {
27 
28     @Autowired
29     private MyBean myBean;
30 
31     @Test
32     public void mockStaticMethod() throws Exception {
33         // Given
34         final long expectedId = 2L;
35         mockStatic(IdGenerator.class);
36         when(IdGenerator.generateNewId()).thenReturn(expectedId);
37 
38         // When
39         final Message message = myBean.generateMessage();
40 
41         // Then
42         assertEquals(expectedId, message.getId());
43         assertEquals("My bean message", message.getContent());
44     }
45 }

可是，本身在使用时，并未生效

1 PowerMockito.doAnswer(e -> {
2             String key = (String) e.getArguments()[0];
3             。。。
4             }
5         }).when(exportEmployeeCSV, "getSex", anyString());

目的是模拟私有方法，而且不执行私有方法内部的代码，可是屡次调整代码仍是会执行内部代码。

继续看评论，好像是版本问题

 

 修改成最新版本，从新运行测试用例，Green Bar！
