JDK 11 + JUnit 5 +拼图:Junit无法运行"module-info"的测试 [英] JDK 11 + JUnit 5 + Jigsaw: Junit fails to run tests for `module-info`
问题描述
我尝试在Gradle项目中使用JUnit 5. compileJava和compileTestJava都成功，但是test失败，并显示奇怪的消息Could not execute test class 'module-info'.(来自stacktrace的消息):
I try to use JUnit 5 in a Gradle project. compileJava and compileTestJava both succeed, but test fails with the strange message Could not execute test class 'module-info'. (message from stacktrace):
> Task :test FAILED
FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':test'.
> There were failing tests. See the report at: file:///Users/axel/git/utility/build/reports/tests/test/index.html
测试结果文件提示我"failed to execute tests"，但是堆栈跟踪看起来很奇怪.看来JUnit试图运行与我的module-info.java文件相对应的类:
The test result file hints me that "failed to execute tests", but the stack trace looks weird. It seems JUnit is trying to run the class corresponding to my module-info.java file:
org.gradle.api.internal.tasks.testing.TestSuiteExecutionException: Could not execute test class 'module-info'.

有人知道如何告诉JUnit不要尝试运行module-info或任何其他解决方法吗?
Does anyone know how to tell JUnit not to try to run module-info or any other workaround?
推荐答案
在测试运行时忽略module-info.class是对类路径进行排序" :
Ignoring module-info.class at test-runtime is "Resort to the class-path": https://sormuras.github.io/blog/2018-09-11-testing-in-the-modular-world#resort-to-the-classpath -- your tests may access internal classes as before. All modular boundaries are discarded.
如果要在进行白盒测试时留在模块化世界中，则需要将主模块和测试模块修补到一个模块中.在测试编译或测试运行时.有关测试模式的更多信息，也可以在上面链接的博客中找到.
If you want stay in the modular world when doing white box tests, you need to patch your main and test modules into a single one. Either at test compile or test runtime. More information about that test modes can also be found in the blog linked above.
对于Gradle设置，您可以使用JUnit https://guides.gradle.org/building-java-9-modules/和/或使用> https://github.com/zyxist/chainsaw
For a Gradle setup you may either use the JUnit ConsoleLauncher manually or re-configure the Gradle runtime paths like described here https://guides.gradle.org/building-java-9-modules/ and/or use https://github.com/zyxist/chainsaw
