We have implemented Integration tests for gradle plugins using Testkit. I am looking to get the code coverage reports for these Integration tests using Jacoco. I have addded Jacoco plugin , but that doesn’t seems to generate the proper report, it always shows 0% code covered. Do anyone have sugges…

Tests executed with the TestKit are run in a daemon JVM. You’ll need to tell the daemon JVM to set the Java agent argument. Something like this should do: -javaagent:/Users/bmuschko/org.jacoco.agent-0.7.1.201405082137-runtime.jar=destfile=/Users/bmuschko/dev/projects/myproj/build/jacoco/testKit.exe…

You can also do this by writing a gradle.properties at the root of your build under test with: org.gradle.jvmargs=«agent args»

Thank you for quick response , I will try your suggestions and let you know.

Were you able to get this to work, i have tried with the gradle.properties approach , adding to the test task jvmArgs but still no joy :frowning:

[image] iwarapter: you able to get this to work, i have tried with the gradle.properties approach , a I tried also both, adding a gradle.properties or using .withJvmArguments(…) but both approached didn’t forward the arguments correctly to testkit. Is it possible that something is missing at …

I did get this to work, to ensure i always had the correct jacoco runtime available i added a configuration with the dependency and then wrote the correct org.gradle.jvmargs to the gradle.properties file before then running the build: ./gradlew setupJacocoProps ./gradlew integTest etc configu…

Thanks for the answer! But to me it looks like you use this for your normal build… Or did you run this with testkit, setting the build up with: GradleRunner.create().withJvmArguments(…)? For the normal build this works for me, too. But the GradleRunner ignores my additional jvm properties. Thoma…

Im not passing anything to my integration tests, just creating the gradle.properties, running the tests, then generating the reports(html/xml etc). Do you have a project on github i can look at might be able to see whats happening.

FYI - I had to tweak this solution slightly for windows as backslashes were causing it to fail More info at Testkit Jacoco Coverage
