Thanks for the reply.
What should I be looking at in the log? I know that there is an error being thrown in one of the groovy scripts. But if that triggers a failed Testcase in the testrunner summary, I would expect it would also trigger a failed testcase in de report. Even if we fix that error and we have a "Green" run, all counts (of testSuites, testcases, teststeps and assertions) are still way different in both reports. It seems like that the testrunner uses a different "source" than the report for the summary...
