I guess what happens here is waitForRendering(obj) is not enough to wait for the warning to be output.
I guessed that would have been enough, since the labels' text is set in initialization phase, and not as a late assignment. The Image is loaded async by default (afaik), so maybe what happens is the text is first rendered without the image and then the image finishes its loading process (with a failure, as the file does not exist) and outputs the warning. But at that point the test could already be finished, as the first render was enough to let it through "waitForRendering". Because of that, I guess what happens is the warning is output after destroy() is called (that just schedules the destruction of the item, it does not do it immediately), i.e. when the test is already finished. As a consequence, the test fails. I have just pushed an MR as a tentative fix, as I could not reproduce the issue locally, not even playing with cpulimit :( -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to ubuntu-ui-toolkit in Ubuntu. https://bugs.launchpad.net/bugs/1571426 Title: tst_slotslayout is flaky Status in ubuntu-ui-toolkit package in Ubuntu: Confirmed Bug description: I got a failure on CI with tst_slotslayout: Executing dbus-test-runner --task gdb -p --quiet -n tst_slotslayout.qml -m 500 -p --batch -p -ex -p 'set print thread-events off' -p -ex -p run -p -ex -p bt -p --return-child-result -p --args -p /tmp/buildd/ubuntu-ui-toolkit-gles-1.3.1872+16.04.20160308/tests/unit_x11/tst_components/tst_components -p -input -p tst_slotslayout.qml -p -maxwarnings -p 100 -p -o -p /tmp/buildd/ubuntu-ui-toolkit-gles-1.3.1872+16.04.20160308/tests/test_tst_slotslayout.qml.xml,xunitxml -p -o -p -,txt Working directory: /tmp/buildd/ubuntu-ui-toolkit-gles-1.3.1872+16.04.20160308/tests/unit_x11/tst_components DBus daemon: unix:abstract=/tmp/dbus-EJFObKuEFm,guid=d5fc837e49f55972e9b2c748571133ef tst_slotslayout.qml: Started with PID: 28926 Undefined command: "".
