Question

遗留最终类中有一个静态void自定义日志方法，它接受两个参数并调用另一个类中的方法，以便在记录器中记录实际数据（控制台或文件依赖于配置）。现在我想知道是否有办法验证log(Object param1, String param2)是否至少被调用过一次？

请注意：SomeClass.actualLogMethod()超出了我的测试范围，所以我只需要验证delete()方法

我在这里看到了一些关于如何模拟一个返回类型不是void的静态方法的解决方案。但是我如何模拟一个返回最终类内部的void的静态方法，如下面的情况？有没有办法我可以使用Powermock验证它的调用。比如使用Mockito.verify()或类似的东西？

public final class LegacyFinalClass{

      public static void log(String param1, Object param2) {
                SomeClass.actualLogMethod(dt, ss);
      }

 }

@Test
public void testDelete() {
    PowerMockito.mockStatic(LegacyFinalClass.class);  
    Object param1 = "logObject"
    String param2 = "some string"
    Mockito.verify(LegacyFinalClass.class).getMethod("log",new Class[]{Object.class, String.class).invoke(param1, parm2);

}

But this fails with this error : 
Wanted but not invoked LegacyFinalClass.getMethod(
    "logDuration",
    interface org.apache.logging.log4j.Logger,
    interface org.apache.logging.log4j.Logger,
    long
);
Actually, there were zero interactions with this mock.

我在想是否需要调用PowerMockito.doNothing().doCallRealMethod().但是我不确定在我需要验证是否调用了log方法的情况下我是如何使用它的。

Junit：验证在最终的Class中调用静态void方法
