Link the instrumented code with the tests in the Clover html report

We're running Clover 3.2.0 for Grails (2.2.4) in a Bamboo build. The build is run using Gradle 1.8.


One of the developers thought it would be handy if she could determine from the Clover html report just which tests a particular line of code was called from. Is there a way to have Clover show this in the reports?

Yes, it's possible. In case when some source line is covered by test, it has a dark green or a dark yellow stripe. You can click on the left page margin to open a dialog window with a list of tests hitting given line.

You can also click on the 'Select tests to highlight the test coverage' link (it's located between file metrics and source code sections) to open a dialog with a list of tests hitting current source file. In this dialog you can select one or more tests to highlight code covered by them.

Please see the page to learn more about Clover's HTML report.

Thanks for the reply. It looks like we do have this in the reports, just not on all the instrumented files. I will dig into why some files show the tests and others don't.

 It looks like we do have this in the reports, just not on all the instrumented files.

1) Please check if you have compiled all your tests with Clover as well as executed all of them. If some test was not instrumented or did not run, you'll simply won't see it in a report. Check if you see given test class(es) in a report and that they have green coverage.

2) Please check if you run test classes and application classes in separate JVMs. For example: a maven-cargo-plugin is used to start container on the fly; an application is being deployed to a test machine; etc. In such case you will need to configure a Distributed Coverage feature in order to track per-test coverage across multiple JVMs.

3) Please check if Clover correctly detected your test classes - they shall be listed on the "Test code" tab in a report. Clover recognizes JUnit, TestNG and Spock. In case you use a different test framework you may have to set up test patterns manually.

4) Please check if you don't see any warnings in a build log, such as "Ignoring coverage recording". See Troubleshooting+Reports for few typical cases.
