我有一个这样的代码，我想为其编写单元测试。

public class TestClass {

private final Executor executor;
private final Handler handler;

TestClass(Executor executor, Handler handler) {
    this.executor = executor;
    this.handler = handler;
}

void doSomething(String param1) {
    executor.execute(new Runnable() {
        @Override
        public void run() {
            //do something
            handler.callHandler();
        }
    });
}
}

我如何使用Mockito / Powermockito来验证是否调用了callHandler（）方法。
