Qml tests using TestCase

Krille

Thanks for your answer. So in summary I have tried the following command:

clickable --arch="amd64" run "xvfb-run -a qmltestrunner"

Now there is no more a graphical problem and no other error. But nothing happens after executing this command except:

Using docker container "clickable/ubuntu-sdk:16.04-amd64-5a95c706-276c-493d-9fff-1507a27ab289"

And then it hangs forever.

Hmm... It's possible that you also need to set QT_QPA_PLATFORM=xcb either using export or by putting it before your command.

No, that is not the problem. Qt will select that automatically.

@Krille Ah, sorry. I forgot the extra option one needs to ensure color depth of the virtual display.

Try xvfb-run -a -s '-screen 0 540x960x24' qmltestrunner instead.

Not sure why clickable didn't show you the error and exit, though. Maybe a bug in clickable?

Krille

Okay, so now I've tested:

clickable --arch="amd64" run "xfvb-run -a -s '-screen 0 540x960x24' qmltestrunner"

Leads me to:

bash: xfvb-run: command not found

Maybe we need to install xfvb in the container? Is there a way how I can install this in the container by myself?

UniSuperBox

Sorry... xvfb, not xfvb. It stands for "X Virtual FrameBuffer."

@Krille Sorry, was a typo. I've edited the post now. It's xvfb-run

Krille

Haha okay. So now:

clickable --arch="amd64" run "xvfb-run -a -s '-screen 0 540x960x24' qmltestrunner"

And again the previous result: Nothing happens anymore I will try to run the command in the container to get an error report...

@Krille Hi. I don't know anything about what you are doing but my eyes see again xfvb above whereas it is spoken about xvfb. Just to be sure it's normal, i prefered to prevent you.

Krille

@domubpkm Oh, sure sorry. But nothing changes...

Btw I have found that this is propably the same reason why the UI tests (at least) in the messages app are still disabled: https://github.com/ubports/messaging-app/blob/xenial/tests/qml/CMakeLists.txt#L18

The tests aren't disabled. If xvfb is installed and tests are run, then these tests which depend on xvfb should be run too. If however, you are using crossbuilder then the tests will not be run, because tests do not get run during the build then, as you cannot run arm binaries native on x86.
