Java PowerMock和Mockito未完成验证异常
我很难让PowerMock和Mockito工作 我正在使用这些版本。应该是Java PowerMock和Mockito未完成验证异常,java,mockito,testng,powermock,powermockito,Java,Mockito,Testng,Powermock,Powermockito,我很难让PowerMock和Mockito工作 我正在使用这些版本。应该是 powermock core v 1.7.4 powermock api mockito v 1.7.4 powermock-module-junit4 v1.7.4 mockito所有版本1.10.19 我也在使用TestNG,但我不认为这对测试结果有任何影响 我想模拟一个对象,在模拟对象上调用一个方法,并验证在模拟对象方法中是否调用过一次私有方法 我构建了一个例子,希望能解释我想要实现的目标 public cla
- powermock core v 1.7.4
- powermock api mockito v 1.7.4
- powermock-module-junit4 v1.7.4
- mockito所有版本1.10.19
public class MyClass {
public void execute(Object o) {
valid(o);
}
private boolean valid(Object o) {
return o != null;
}
}
这是我的测试课
@RunWith(PowerMockRunner.class)
@PrepareForTest(MyClass.class)
public class TestClass {
@After
public void validate() {
validateMockitoUsage();
}
@Test
public void executeTest() throws Exception {
//Initialize the Class and create the spy
MyClass myClass = PowerMockito.spy(new MyClass());
//Execute the method which I wish to test
myClass.execute(null);
//I want to verify that the private valid method was called once.
PowerMockito.verifyPrivate(myClass, times(1)).invoke("valid", anyObject());
}
}
我得到以下错误:
org.mockito.exceptions.misusing.UnfinishedVerificationException:
Missing method call for verify(mock) here:
-> at TestClass.executeTest(MyClass.java:14)
Example of correct verification:
verify(mock).doSomething()
Also, this error might show up because you verify either of:
final/private/equals()/hashCode() methods.
Those methods *cannot* be stubbed/verified.
Mocking methods declared on non-public parent classes is not supported.

我试过搜索,但找不到解决问题的方法。我相信这是一个常见的错误,我使用PowerMock/Mockito是错误的。我自己无法在junit4上复制这个问题。原来这是TestNG的问题。当您使用TestNG运行测试时,@RunWith注释被忽略,因为它是JUnit特有的 要实现此功能,您有两个选项:
确保在使用powermock测试私有方法时添加了这两个注释:
@RunWith(PowerMockRunner.class)
@PrepareForTest(<Class_containing_pvt_method>.class)
@RunWith(PowerMockRunner.class)
@PrepareForTest(.class)
@RunWith注释将powermock初始化为junit的运行程序
@PrepareForTest在模拟final类时使用注释,此类具有final、private、static或native方法,以便powermock可以从这些类的字节码中读取(因为java不允许对私有方法进行反射).我看到的第一件事是,您可能应该准备
MyClass
,而不是TestClass
。看看能不能帮上忙?很好。不幸的是,当我写这个问题时,这只是一个打字错误。我已经修复了打字错误。我无法复制此问题。当我运行它时,它工作正常。我只是需要稍微更改一下匹配器。在您报告无法复制此问题后,我发现了此问题。问题是毕竟TestNG。当我使用junit4时,一切都很完美。谢谢大家的建议,通常都是些小事;)报告您无法重现问题通常是解决方案。您可以用您的评论创建一个答案,我将接受它。
