Fix the skip-check in TestMethods::invokeTest() TestMethods::invokeTest() has an outer loop on global data (albeit with a comment that said otherwise). On its first cycle, we run the test function's *_data() method, if it has one; there is an inner loop on the rows this created. If the *_data() QSKIP()s, we need to skip the whole test; otherwise, a QSKIP() in one sub-test should not lead to skipping the remaining sub-tests. Moved the check for *_data() QSKIP()ping to right after *_data() returns, inside the "first global cycle" block that runs it. Previously, this check was done before entering the loop on local data rows, but outside that "first global cycle" block: consequently, later global cycles would fall foul of this check (even though the *_data() hasn't been run in this cycle, much less QSKIP()ped in it) if the last sub-test of the previous global cycle had QSKIP()ped. When running a single test for one specific data row, if the test's *_data() QSKIP()ped, this misplaced check would also have lead to a misleading "Unknown testdata" warning. Changed testlib/selftests' tst_globaldata::skipSingle() to trigger the bug (by having its last local row of first global row skip, which caused the second global row to be omitted) to verify this is also fixed; and amended one of its comments to reflect what's now to be expected. Updated the test's expected output files. Task-number: QTBUG-61774 Change-Id: I99596b595c6d1184038f23383844c6ff51a0cd91 Reviewed-by: Jędrzej Nowacki <jedrzej.nowacki@qt.io>
