Coverage for JUnit Plugin tests?

[Stephan Druskat]

Dear Group,

I'm wondering about the following issue I've run into. I've a group of JUnit Plugin tests for my Eclipse RCP application. From within Eclipse, I run them via a Run Configuration with option "Run all tests from selected project...". When I run them, they work just fine (and all are passing).

However, when I select the same Run Config via Run > Coverage, one of the test fails with a NoClassDefFoundError. I get the same when trying to run the test in question via plain JUnit.

Is there a way to get Coverage for a set of JUnit Plugin tests?

Thanks!
Stephan

Hi Stephan,

can you please provide the full stack trace?

Hi Marc,

Thanks for getting back to me. Unfortunately I have since deleted the test in question (and re-implemented as an SWTBot test). So I cannot reproduce the error. I'm new to TDD, so I might have just implemented something wrong.

However, I get another strange side-effect now, namely that VisualVM starts, whenever I run the run configuration for the JUnit Plugin Tests?!? All is fine when I just run the run configuration for my product though, so I guess I'll just use that in the future.

Nevertheless I have a two simple questions that perhaps you or someone else could answer quickly?

1. Am I supposed to run Coverage... on Test or on Eclipse Application run configurations?
2. Does EclEmma take SWTBot (or RCPTT) tests into account or just "plain" unit tests?

Many thanks indeed! A great tool overall!

Hi Stephan,

the interference with VisualVM is a known issue which will be fixed in an upcoming release:

https://github.com/jacoco/eclemma/issues/112

The only workaround fir now is to uninstall the VisualVM plugin.

Yes, SWT Bot tests are supported, please see documentation for a full list of supported launch types:
