如何判断JUnit IntelliJ的哪个特定版本正在使用？ [英] How can I tell which specific version of JUnit IntelliJ is using?

问题描述

我已经开始研究已经设置了IntelliJ环境的大型项目。环境包括JUnit，我可以成功运行单元测试。我已经看过屏幕，我可以指定JUnit 3或JUnit 4的用法，但是如何确定使用哪个特定的JUnit来运行我的测试，例如JUnit 4.11？

I've started working on a large project where the IntelliJ environment has already been set up. The environment includes JUnit, and I can successfully run unit tests. I've seen screens where I can specify the usage of JUnit 3 or JUnit 4, but how can I determine which specific JUnit is being used to run my tests, e.g., JUnit 4.11?

我已经尝试过打开模块设置。当我查看Dependencies选项卡时，我没有看到任何与JUnit有关的内容，尽管我可以运行JUnit测试。

I have already tried "Open Module Settings". When I look at the "Dependencies" tab, I don't see anything relating to JUnit, although I can run JUnit tests.

推荐答案

使用哪个jar？

当您从IntelliJ运行JUnit时，控制台输出的第一行显示您的类路径。您可以使用Ctrl + F查找任何junit引用。

When you run JUnit from IntelliJ, the very first line of the console output displays your classpath. You can use Ctrl+F to find any "junit" references.

junit-rt.jar是JetBrains可能编写的帮助程序库。通过使用7-zip打开jar作为存档，您会发现其中唯一的包是在com.intellij

junit-rt.jar is a helper library that JetBrains might have written. By opening the jar as an archive with 7-zip, you will find that the only package inside it is under com.intellij

根据Java：类路径JVM中的多个资源中的哪一个需要？对junit的第一个引用。 jar是你将要使用的。

According to Java: Which of multiple resources on classpath JVM takes? the first reference to junit.jar is the one you will use.

那个罐子的版本是什么？

一旦知道正在使用哪个jar，就有很多方法可以找到该版本。一种是使用此代码取自 https://stackoverflow.com/a/16729507/1405720

Once you know which jar is being used, there are a number of ways to find the version. One is to use this code taken from https://stackoverflow.com/a/16729507/1405720

System.out.println("JUnit version is: " + Version.id());

另一种方法可能是打开jar作为档案，看看你是否可以从中找出它那里。
