There is a problem with androidtestrunner. It parses only the last run tests set. In this case, test sets cannot be run together.
BUG.diff is attached. It contains a patch on qtBase repository with dummy tests added.
One of the test set contains only QVERIFY(true); Second test set contains only QVERIFY(false); . If they are run together only last is parsed and test is finished as 100% tests passed
It can be noticed in adb logcat that both test sets are run.
