我已经看到很多关于与 maven surefire 并行运行 JUnit 测试的主题,但我还没有看到处理这个特定问题的答案。
简而言之:测试方法是并行执行的(那里有好消息),但 prop 并不能限制我的线程。最终目标是并行化我的 web 驱动程序和 appium 运行,但我希望能够首先控制可能的线程总数。
下面的代码片段来自一个虚拟项目,仅用于演示。按照apache 文档,它看起来并没有比下面的更多。

Thread.sleep(5000);
}

Thread.sleep(5000);

我希望使用提供的 pom 配置完整运行这个类需要比 25 秒长一点的时间(10 个睡眠 5 秒,一次运行两个)。实际运行时间略多于 5 秒:
Tests run: 10, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 5.022 sec - in ExampleTest
更改该 threadCountMethods 道具对运行时没有影响(看起来所有方法都在并行运行,而不考虑 threadCount 道具)。
任何投入将不胜感激; 谢谢!
