Start with org.jetbrains.plugins.grails.editor.GenerateTestsAction.java and GrailsTestUtils.java, especially the calls shown in the stack trace. Read the IndexNotReadyException documentation and reproduce the failure by pressing Tests while the project index is still building. Done means the action no longer fails with this exception in that situation.
