jacoco and test(ng): I'm getting quasi-empty test.exec and testng.exec files?

[Dávid Karnok]

Hi!

I'm experimenting with the Project Loom JDK 14 build (I know, it is not really supported yet) and managed to get many things working, except generating a jacoco report.

Project: https://github.com/akarnokd/RxJavaFiberInterop/tree/2c6d00477b732c38b7b2c1f2118a6c3c97fa77b1

If I run 

gradlew clean test testng jacocoTestReport

the build/jacoco directory contains two files, test.exec and testng.exec, both have size 48 which implies there is no test coverage data at all. There are no errors printed.

Could there be a misconfiguration problem or is it the lack of JDK 14 support with 0.8.4 again?

Thank you for your time.

This is misconfiguration:

as was said in https://groups.google.com/d/msg/jacoco/C0Oa6otd894/HOBOoZP8AwAJ

jacoco.includes

should be

jacoco.includes = ["hu/akarnokd/**"]

and not

jacoco.includes = ["**/hu/akarnokd/**"]

as you have in https://github.com/akarnokd/RxJavaFiberInterop/blob/2c6d00477b732c38b7b2c1f2118a6c3c97fa77b1/build.gradle#L103

because last one matches only class names such as "foo/hu/akarnokd/Bar",

whereas your class names start with "hu/akarnokd". 

Following report is generated with correct includes:

 

 

Thank you for your time.
