How to mark a source folder as test source folder

[phermsdorf]

Hi,

we have a typical eclipse test setup where a test fragment contains the junit tests for a host plugin with the same package structure as the host plugin.

We now have the problem that SonarLint identifies the test sources as production code since it looks into the build path configuration if the setting "Contains test sources" is active.

The problem is that "Maven -> Update project" reset's that setting when enabling it manually.

I tried adding <testSourceDirectory>src</testSourceDirectory> to the pom.xml of the test fragment but that also does not seem to help.

Can there anything else be done to get that setting generated correctly by m2e?

Thanks for any hints on this.

Bye Peter

Is the pom.xml file for the test fragment correctly setting <packaging>eclipse-test-plugin</packaging> ? Do you have m2e-PDE connector installed in your IDE?

As always an example that one can import to see the problem would help!

Import this test project into Eclipse:
https://github.com/eclipse-tycho/tycho/tree/dcce32136630bd2882e94db4915ca80b65675df3/tycho-its/projects/surefire.appArgs

add

	<properties>
		<tycho-version>4.0.13</tycho-version>
	</properties>

to the pom.xml.
Right click on the project-> Build Path -> enable "Contains Test Sources: Yes".
If you have SonarLint installed: no issue in the Test class regarding the assertion, only regarding the "throws Exception".
Right click on the Project: Maven -> Update Project -> OK
Change something in Test.java to trigger SonarLint execution:

In the Build Path settings of the Project the "Contains Test Sources" is reset to No.
