int result = testClass.privateMethod(); System.out.println(result); } } ``` 在这个示例中,我们使用@Mock 注解模拟了 TestClass 类的 privateMethod() 方法,并通过 Mockito 的 when() 方法指定了该方法的返回值。最后,我们在测试方法中调用了这个私有方法,并输出了其返回值。 总之,在Java 中模拟私有方法...
public void testPrivateMethod() { when(myBaseClass.getPrivateMethod()).thenReturn("模拟的返回值"); // 调用私有方法 String result = myBaseClass.getPrivateMethod(); // 断言返回值 assertEquals("模拟的返回值", result); } } ``` 通过以上步骤,我们可以在单元测试中模拟 Java 私有方法。需要注意的...
}privateStringprivateMethod() {return"Private Method"; } } 要测试PrivateMethodClass类的私有方法,可以使用PowerMock进行如下操作: importstaticorg.mockito.Mockito.*;importstaticorg.powermock.api.mockito.PowerMockito.*;importorg.junit.Test;importorg.junit.runner.RunWith;importorg.powermock.core.class...

可以看到publicMethod方法调用了privateMethod,也就是公共方法调用了私有方法。 我们需要对私有方法进行mock 代码语言:javascript 复制 packagecom.banmoon.powerMockitoTest;importcom.banmoon.service.impl.PowerMockitoServiceImpl;importorg.junit.Test;importorg.junit.runner.RunWith;importorg.mockito.InjectMocks;import...

Mockito不支持设置private和final变量,PowerMock的Whitebox无法再使用,不过我们可以利用其它三方库曲线救国,比如apache common包里面的FieldUtils,不过只能设置private变量,final变量还是需要重构代码。 Mock规则多处复用 Mock规则复用是指,为了精简单元测试和提升编写单元测试的效率,我们可以抽取出单元测试中重复的Mock规则,实现...
