Junit Parameterized tests together with Powermock - how?
提问by Anders Hansson
I've been trying to figure out how to run parameterized tests in Junit4 together with PowerMock. The problem is that to use PowerMock you need to decorate your test class with
我一直试图弄清楚如何在 Junit4 中与 PowerMock 一起运行参数化测试。问题是要使用 PowerMock，您需要用
@RunWith(PowerMockRunner.class)
and to use parameterized tests you have to decorate with
并使用参数化测试，你必须装饰
@RunWith(Parameterized.class)
From what I can see they seem mutually excluded!? Is this true? Is there any way around this? I've tried to create a parameterized class within a class running with PowerMock; something like this:
从我所见，它们似乎相互排斥！？这是真的？有没有办法解决？我尝试在使用 PowerMock 运行的类中创建参数化类；像这样：
@RunWith(PowerMockRunner.class)
class MyTestClass {
@RunWith(Parameterized.class)
class ParamTestClass {
// Yadayada
}
}
But unfortunately this doesn't do much good... The ParamTestClassstill doesn't run with PowerMock support (not that surprisingly maybe)... And I've kind of run out of ideas so any help is greatly appreciated!
但不幸的是，这并没有多大好处......ParamTestClass仍然不能在 PowerMock 支持下运行（也许并不奇怪）......而且我的想法已经用完了，所以非常感谢任何帮助！

I had the same issue. Unfortunately it would not let me use a PowerMock Rule due to the JVM I had. Instead of the rule I used RunnerDelegate.
我遇到过同样的问题。不幸的是，由于我拥有的 JVM，它不允许我使用 PowerMock 规则。我使用 RunnerDelegate 代替了规则。
@RunWith(PowerMockRunner.class)
@PowerMockRunnerDelegate(Parameterized.class)

The following solution worked for me!
以下解决方案对我有用！
@RunWith(PowerMockRunner.class)
@PowerMockRunnerDelegate(Parameterized.class)

You can't use two class runners at once, so you will definitely have to write your own test runner to make that happen.
您不能同时使用两个类运行器，因此您肯定必须编写自己的测试运行器来实现这一点。
I don't know anything about Powermock, but after 10 seconds of research, it looks like one solution would be to write a test runner which uses powermock's class loader and runs parameterized tests. If you can figure out how to delegate to the parameterized test runner from within your custom test runner, that might be your best bet.
我对 Powermock 一无所知，但经过 10 秒的研究，看起来一个解决方案是编写一个测试运行程序，它使用 powermock 的类加载器并运行参数化测试。如果您能弄清楚如何从自定义测试运行器中委托给参数化测试运行器，那可能是您最好的选择。
