Junit Test (Mockito, PowerMock) 一个带有void方法和私有值的类

Question

一些示例代码，例如： （我只是添加了更多细节）

 public class A {
      @Autowired
      private Data data;

      @RequestMapping(value="/Boo", method = RequestMethod.GET)
      public void Boo(){        
        data.someMethod();       
  } 
}

我想测试 someMethod() 是否运行。

我尝试过@First 答案，但收到如下错误消息：

java.lang.AbstractMethodError: org.powermock.api.mockito.internal.exceptions.StackTraceCleanerProvider$1.isIn(Ljava/lang/StackTraceElement;)Z
    at org.mockito.internal.exceptions.stacktrace.StackTraceFilter.filter(StackTraceFilter.java:33)
    at org.mockito.internal.exceptions.stacktrace.ConditionalStackTraceFilter.filter(ConditionalStackTraceFilter.java:23)
    at org.mockito.exceptions.base.MockitoException.filterStackTrace(MockitoException.java:44)

Answer 1

@RunWith(MockitoJUnitRunner.class)
public class ATest {

    @InjectMocks
    private A a;

    @Spy
    private Data data;

    @Test
    public void test() {
        // execute
        this.a.Boo();

        // verify
        Mockito.verify(this.data).someMethod();
    }

}
