QTEST_FUNCTION_TIMEOUT is a timeout enforced by QTest as the maximum time for a test function.

Androidtestrunner can not enforce this timeout (mostly because of QTBUG-106478), but it has a separate timeout that concerns the total time of execution of the test, and that defaults to 8 minutes and can be altered with --timeout.

Suggested solution

Set the hardcoded 8min total timeout to 2*QTEST_FUNCTION_TIMEOUT (converted to seconds).
