如何告诉Maven2在新的JVM实例中一个接一个地执行jUnit测试? [英] How to tell Maven2 to execute jUnit tests one by one each in new JVM instance?

问题描述

是否可以告诉Maven2在新的JVM实例(分支)中以串行方式(即，一个接一个地)执行每个jUnit测试.

Is it possible to tell Maven2 to execute every jUnit test in new JVM instance (fork) in serial mode, i.e. one by one.

推荐答案

您必须像解释的通过声明Sytem属性也应该有可能

It should also be possible by just declaring a Sytem property

mvn -DforkMode=always test

如文档中所述:始终"派生每个测试类.我不知道" pertest "设置是否会为每个测试派生.

As described in the documentation: "always" forks for each test-class. I do not know if the "pertest" setting will fork for each test.

感谢@Djebel指出现在已弃用forkMode.有关" Fork选项和并行测试"的详细文档执行"以及如何使用新参数 forkCount 和 reuseForks ，其中还包括以下迁移提示:

Thanks to @Djebel for pointing out that forkMode is deprecated now. There is a detailed documentation on "Fork Options and Parallel Test Execution" and how to use the new parameters forkCount and reuseForks and that also includes the following migration tips:

Old Setting                         New Setting
forkMode=once (default)             forkCount=1 (default), reuseForks=true (default)
forkMode=always                     forkCount=1 (default), reuseForks=false
forkMode=never                      forkCount=0
forkMode=perthread, threadCount=N   forkCount=N, (reuseForks=false, if you did not had that one set)
