全局设置一个JUnit运行器而不是@RunWith [英] Globally setting a JUnit runner instead of @RunWith

问题描述

不用研究JUnit源本身(下一步)，是否有一种简单的方法来设置要在每个测试中使用的默认Runner，而不必在每个测试中都设置@RunWith?我们有大量的单元测试，我希望能够全面增加一些支持而不必更改每个文件.

Without looking into JUnit source itself (my next step) is there an easy way to set the default Runner to be used with every test without having to set @RunWith on every test? We've got a huge pile of unit tests, and I want to be able to add some support across the board without having to change every file.

理想情况下，我希望这样的东西:-Djunit.runner ="com.example.foo".

Ideally I'm hope for something like: -Djunit.runner="com.example.foo".

推荐答案

我认为这不可能在全局范围内定义，但是如果编写自己的主函数是一种选择，则可以通过代码执行类似的操作.您可以创建自定义RunnerBuilder并将其与测试类一起传递给Suite.

I don't think this is possible to define globally, but if writing you own main function is an option, you can do something similar through code. You can create a custom RunnerBuilder and pass it to a Suite together with your test classes.

Class<?>[] testClasses = { TestFoo.class, TestBar.class, ... };
RunnerBuilder runnerBuilder = new RunnerBuilder() {
    @Override
    public Runner runnerForClass(Class<?> testClass) throws Throwable {
        return new MyCustomRunner(testClass);
    }
};
new JUnitCore().run(new Suite(runnerBuilder, testClasses));

它不会与Eclipse中的UI测试运行器集成在一起，但是对于某些自动化测试方案来说，它可能是一个选择.

This won't integrate with UI test runners like the one in Eclipse, but for some automated testing scenarios it could be an option.
