How to enable debug on my JUnit through Gradle test task
提问by mefi
I get into trouble while I try to run my JUnit test through gradle test task. While I run test in eclipse directly with Run As -> JUnit test, everything is ok, test succeeds. But through test task, test always fails. Probably some trouble with encoding of my resource txt file. So I would like to enable debug while I am launching test with gradle
我在尝试通过 gradle 测试任务运行 JUnit 测试时遇到了麻烦。虽然我直接在 Eclipse 中使用 Run As -> JUnit test 运行测试，但一切正常，测试成功。但是通过测试任务，测试总是失败。我的资源 txt 文件的编码可能有些问题。所以我想在使用 gradle 启动测试时启用调试
in build.gradle, my test task now looks like:
在 build.gradle 中，我的测试任务现在看起来像：
test {
tasks.withType(Compile) {
options.encoding = 'UTF-8'
}
}
So what should I do for enable debug? I run gradle tasks from Gradle panel in Eclipse, not from console. Thanks!
那么我应该怎么做才能启用调试？我从 Eclipse 中的 Gradle 面板运行 gradle 任务，而不是从控制台。谢谢！

To debug tests the following argument should be used: --debug-jvm
要调试测试，应使用以下参数： --debug-jvm
For example: gradle test --debug-jvm
Gradle will suspend execution right before running tests and wait for debugger connection on port 5005.
例如：gradle test --debug-jvm
Gradle 将在运行测试之前暂停执行并等待端口 5005 上的调试器连接。
For executing only specific tests see https://docs.gradle.org/current/userguide/java_testing.html#simple_name_pattern
要仅执行特定测试，请参阅https://docs.gradle.org/current/userguide/java_testing.html#simple_name_pattern

As explained under 23.12. Testin the Gradle User Guide, executing gradle test -Dtest.single=MyTestClass -Dtest.debugwill suspend the test JVM upon start, and allows to connect an external debugger (such as the Eclipse debugger) on port 5005.
如下说明23.12. Test在摇篮用户指南，执行gradle test -Dtest.single=MyTestClass -Dtest.debug在启动时将暂停测试JVM，并允许外部调试器（如Eclipse调试器）在端口5005连接。

Putting this here as --debug-jvmdid not work for me, I was able to do this by setting:
把它放在这里--debug-jvm对我不起作用，我可以通过设置来做到这一点：
org.gradle.daemon=true
org.gradle.jvmargs=... -agentlib:jdwp=transport=dt_socket,server=y,suspend=y,address=10999
in
在
~/.gradle/gradle.properties
But when I connect with eclipse debugger for the project none of the breakpoints I've set compile/trigger... I am connected via the debugger, I can see action in the Debug view, whenever I run gradle testfrom command line, like new threads starting/stopping, but can't get breakpoints to trigger, trying to resolve this now...
但是当我为项目连接 eclipse 调试器时，我没有设置编译/触发的断点...我通过调试器连接，我可以在调试视图中看到操作，每当我从命令行运行时gradle test，就像新线程一样启动/停止，但无法触发断点，现在尝试解决此问题...
Fyi to stop deamon run gradle --stop
仅供参考以停止守护进程 gradle --stop
Other solution
其他解决方案
Leaving above as reference, this worked for triggering break points in tests, I turned off deamon as I could not get it to work properly:
以上留作参考，这适用于在测试中触发断点，我关闭了守护进程，因为我无法让它正常工作：
Using directions from this article: http://blogs.steeplesoft.com/posts/2013/gradle-tip-attaching-a-debugger.html
使用本文中的说明：http: //blogs.steeplesoft.com/posts/2013/gradle-tip-attaching-a-debugger.html
test {
if (System.getProperty('DEBUG', 'false') == 'true') {
jvmArgs '-Xdebug',
'-Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=10999'
}
}
Executed via gradle test -DDEBUG=true
执行通过 gradle test -DDEBUG=true
Solution when using the JUnit Platform Gradle plugin
使用JUnit Platform Gradle插件时的解决方法
The solution above won't work when using org.junit.platform.gradle.plugin.
使用org.junit.platform.gradle.plugin.
Instead it should be replaced by:
相反，它应该替换为：
junitPlatformTest {
if (System.getProperty('DEBUG', 'false') == 'true') {
jvmArgs '-Xdebug',
'-Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=10999'
}
}

I'm on 4.6 (gradle) and I'm able to debug my tests when I have this in my build.gradle file:
我在 4.6 (gradle) 上，当我的 build.gradle 文件中有这个时，我可以调试我的测试：
test {
debug true
}
