单元测试类在Eclipse中运行旧版本 [英] Unit test class runs old version in eclipse

问题描述

我的项目中有一个JUnit测试类，该类会逐渐更新-我每隔几周添加一次测试，有时还会修改测试的代码.

I have a JUnit test class in my project which is updated incrementally - I add tests every few weeks and sometimes modify the tests' code.

令人惊讶的是，当我使用Eclipse JUnit Runner 4运行测试类时，它将运行旧代码(在更新之前)而不是新代码.我可以更改代码，添加或删除测试，但它仍然可以运行旧代码.

Surprisingly, when I run the test class using eclipse JUnit Runner 4, it runs my old code (before the update) and not the new one. I can change the code, add or remove tests but it still runs the old code.

我试图找出问题所在，并运行一个我刚刚编写的测试，却得到了臭名昭著的无根测试"错误，而没有任何堆栈跟踪信息，可以让我知道问题出在哪里.

I tried to isolate the problem and run a single test that I've just written and got the infamous "Unrooted tests" error without any stack trace to give me a clue what the problem is.

我做了一些研究，并且根据这里的其他一些线程，很多人都遇到了有关JUnit 3 \ JUnit 4兼容性的问题，但是这里不是这种情况-我用@Test注释了我的所有测试，不要扩展TestCase类.

I did some research and according to a few other threads here, many people encountered this problem with regards to JUnit 3 \ JUnit 4 compatibility, but this is not the case here - I annotate all my tests with @Test and I do NOT extends the TestCase class.

清洁/构建所有Eclipse项目无济于事. 但是，当我mvn clean install我的项目时，此问题确实可以解决，但这会花费太多时间. 另外，重命名该类(eclipse中的Alt + Shift + R)可以使新代码立即运行，但是将其重命名为其原始(有效)名称，可以使旧代码再次运行(WTF?)

Cleaning / Building all eclipse projects doesn't help. However, this problem does work itself around when I mvn clean install my project, but this takes too much time. Also, renaming the class (Alt+Shift+R in eclipse) gets the new code to run immediately, but renaming it back to its original (and valid) name, gets the old code to run again (WTF?)

推荐答案

我设法自己解决了这个问题(受到Harlard的评论的启发). 在检查了项目的目标目录后，我注意到其中的test-classes目录不包含测试的二进制文件. 然后，我注意到我将类放错了src/test/java中，并放置在与我的项目的包结构不符的包结构中，它们是src/test/java的直接子目录. 因此，eclipse不能将它们放置在正确的位置，并且为它们生成二进制文件的唯一方法是执行maven构建. 将我所有的测试类重构为正确的包结构后，一切运行正常.

I managed to solve the problem on my own (inspired by a comment contributed by Harlard). After examining the target directory of my project, I noticed that the test-classes dir inside it doesn't include the binaries of my test. I then noticed that I misplaced the classes within src/test/java and put them in a package structure that doesn't conform to the package structure of my project, they were direct sub-directories of src/test/java. Therefore, eclipse didn't put them in the correct place and the only way to generate binaries for them was by executing a maven build. After refactoring all my test classes to the correct package structure, everything worked perfectly.
