JUnit是否按顺序执行测试用例？ [英] Does JUnit execute test cases sequentially?

问题描述

在帖子中，我问了一个小问题一个更大的问题。由于我还没有得到回复，我在这里提出了我的问题：

In this post, I asked a small question as part of a bigger problem. Since I didn't get responses yet, I put my question here:

假设JUnit按顺序执行测试用例是否合理：测试用例在下一个测试用例之前结束开始。它是否在JUnit版本之间有所不同（我的优先级是在JUnit4上）？如果没有，是否有一种简单的方法可以强制JUnit按顺序执行测试？

Is it reasonable to suppose that JUnit executes test cases sequentially: a test case ends befores the next one starts. Does it differ between JUnit versions (my priority is on JUnit4)? And if not, is there a simple way to force JUnit to execute tests sequentially?

谢谢

推荐答案

是的，默认情况下我相信它会按顺序运行测试。

Yes, by default I believe it runs tests sequentially.

JUnit 4.6引入了一个实验 ParallelRunner 并行运行测试 - 我不知道它的当前状态。我希望并行性默认仍然是选择加入功能。 （从其他答案来看，看起来现在这里仍然存在，但形式略有不同 - 仍然选择加入。）

JUnit 4.6 introduced an experimental ParallelRunner to run tests in parallel - I don't know of its current status. I would expect parallelism to remain an "opt-in" feature by default though. (Judging by other answers, it looks like this is now here to stay but in a slightly different form - and still opt-in.)
