Unit tests for birt-functions-lib, when run in eclipse (right-click on test-src -> Run As -> JUnit Test), all fail. Most fail because:

java.lang.AssertionError: org.eclipse.birt.report.engine.api.UnsupportedFormatException: The output format HTML is not supported.

When examining the unit test in Run Configurations it can be seen that org.eclipse.birt.report.engine.emitter.html is not included in the Plug-in Dependencies and this is probably causing the error. However that plugin is not required by birt-functions-lib and should not be included. Also the tests require Mockito that that should not be included in the plugin. Therefore the unit tests should be in a separate project and not included in birt-functions-lib.

I created a separate plugin for the unit tests and added as many dependencies as I could to MANIFEST.MF. I also added the latest mockito-core, byte-buddy, and objenesis to the runtime classpath. This still failed when the unit tests were run as plain JUnit Tests from the run menu, but then I got the idea from this stack-overflow question to use the JUnit Plug-in Test run configuration. With experimentation I found that I could get all the unit tests but one to run successfully by manually selecting the plugins, selecting everything, and checking "Include required Plug-ins automatically while launching". The only test that failed was AppendLibraryContentTest because Mockito wasn't doing what was expected.

Turns out AppendLibraryContentTest could be fixed by stubbing reportDE.getRoot(). All the unit tests now work when run as JUnit Plug-In Tests in eclipse.

Successfully building birt.functions.lib with maven. All test except SetChartPaletteTest.testExecute1 successfully work with maven. That test fails because of a null pointer exception deep inside HTML rendering. Debugging as described in this maven surefire page does not work. Method one, for forked tests, does not pause. Method two, for non-forked tests, pauses but no breakpoints work. Still trying to solve this.

Made compatible with BIRT 4.11. Rebuilt with maven and all tests run with maven. SetChartPaletteTest.testExecute1 still failing.
