Nested JUnit 5 tests are not included

[rodm]

Using SonarQube 8.9 with the Groovy plugin, v1.7 doesn't include unit tests written in Groovy using the new JUnit 5 @Nested annotation. This isn't the case for tests written in Java, I found the following thread and issue. It looks as if the Groovy plugin has the same problem.

I've attached a sample project based on the sample from SONARJAVA-3222 but with unit tests written in Groovy, running the following command should show 2 tests executing and passing but only 1 appears in SonarQube.

./gradlew clean build sonarqube
