Maven surfire测试reusefork vs parallel

Now I have a complete project and I wanted to parallel the testing in maven. If I set the parallel option, mine tests fails cause of DirtiesContexts. (Even if I annotate the testclasses with @DirtiesContext(classMode=ClassMode.AFTER_CLASS))

现在我有一个完整的项目，我想在maven中并行测试。如果我设置了并行选项，则我的测试失败导致DirtiesContexts。 （即使我用@DirtiesContext注释测试类（classMode = ClassMode.AFTER_CLASS））

I'm not putting the stacktrace here but its failed to load applicationcontext cause he can't register the applicationcontext cause its already there.

我没有把堆栈跟踪放在这里，但是它无法加载applicationcontext，因为他无法注册applicationcontext，因为它已经存在。

If I use reusefork it tests succeeds even without annotating the DirtiesContext.

如果我使用reusefork，即使没有注释DirtiesContext，测试也会成功。

When you use reusefork you will create always new VM for each fork (and that's the reason why it is succesfull). (see doc here : http://maven.apache.org/surefire/maven-surefire-plugin/test-mojo.html)

当您使用reusefork时，您将为每个fork创建总是新的VM（这就是为什么它成功的原因）。 （请参阅此处的文档：http：//maven.apache.org/surefire/maven-surefire-plugin/test-mojo.html）

With parallel you will not do this so normally this would have less resources needed.

通过并行，您将不会这样做，所以通常这将需要更少的资源。

So now of to the question :

那么现在问题是：

1. The link of doc says with parallel for TestNG only, but here they speak of JUnit 4.7 and higher so I'm confused, what's the correct documentation?
2. doc的链接仅与TestNG并行，但在这里他们谈到JUnit 4.7及更高版本，所以我很困惑，什么是正确的文档？
3. Is parallel testing better dan reusefork?
4. 并行测试是否更好dan reusefork？
5. If its better, how can I fix the DirtiesContext?
6. 如果它更好，我该如何修复DirtiesContext？

Thx in advance.

Thx提前。
