JBoss Tools tycho build now provides code coverage report for eclipse-test-plugins. All eclipse-test-plugin pom.xml files provide meta information about what bundles are instrumented and what classes are included in coverage report through properties:
- emma.filter - emma filter to define what packages to include to or to exclude from report
- emma.instrument.bundles - comma separated list of bundles to be instrumented on the fly during tests execution
Here is an example from org.jboss.tools.common.test plug-ins
<properties> <emma.filter>org.jboss.tools.common*</emma.filter> <emma.instrument.bundles>org.jboss.tools.common</emma.instrument.bundles> </properties>
To enable code coverage report generation during build
-Dcoverage
system property should be added to build command line. It activates maven coverage profile to generate coverage reports on per test plug-in basis in text and xml formats. Text reports are printed out to the build console output like

Reports are generated to /target/emma folder of test plug-in.
To enable code coverage for your test plug-in just add properties listed above to your plug-in pom.xml file and activate coverage profile as it explained above.
