PowerMockito似乎无法匹配并重载方法 [英] PowerMockito can't seem to match and overloaded method
本文介绍了PowerMockito似乎无法匹配并重载方法的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我似乎无法克服这个问题.我正在尝试模拟一个带有1个参数的重载方法
I can't seem to overcome this problem. I'm trying to mock an overloaded method that takes 1 argument
class ClassWithOverloadedMethod {
private boolean isValid(ClassA a){
return true;
}
private boolean isValid(ClassB B){
return false;
}
}
模拟设置
ClassWithOverloadedMethod uut = PowerMockito.spy(new ClassWithOverloadedMethod());
PowerMockito.doReturn(true).when(uut, "isValid", Matchers.isA(ClassB.class));
但是PowerMockito不断返回此错误
but PowerMockito keeps returning this error
java.lang.NullPointerException

我正在将PowerMockito 1.5与Mockito 1.9.5一起使用
I'm using PowerMockito 1.5 with Mockito 1.9.5
推荐答案
尝试使用接受Method对象的when()方法之一.您可以使用Whitebox通过指定参数 type 来检索所需的方法实例，该参数可以解决当前问题.
Try using one of the when() methods that accepts a Method object. You can use Whitebox to retrieve the method instance you want by specifying the parameter type which should get around your current issue.
类似
Method m = Whitebox.getMethod(ClassWithOverloadedMethod.class, ClassB.class);
PowerMockito.doReturn(true).when(uut, m).withArguments(Matchers.any(ClassB.class));
