Running unittests that require access to the display server crash

[Omer Akram]

trying to run QtMultimedia tests on the phone on Mir results in the test crashing on the very start with the below error:

QUbuntu: Could not create application instance
Aborted (core dumped)

I also tried specifying a desktop file and in that case I get http://paste.ubuntu.com/6447502/
Running these tests is important on the phone to make sure that QtMultimedia upstream APIs are working with the Ubuntu phone backends.

Right, we need some kind of a wrapper that will let us just run a binary via upstart like any other .desktop-file-having app.

Short-term solution: if things don't actually need access to the display, exporting QT_QPA_PLATFORM=minimal helps.

A first stab at such a wrapper, courtesy of mzanetti:

/usr/share/applications/dummyrunner.desktop:
---------------------------
[Desktop Entry]
Type=Application
Name=Dummy
GenericName=dummy
Comment=Dummy desktop file
Exec=/home/phablet/dummyrunner %u
Terminal=false
X-Ubuntu-Touch=true
---------------------------

/home/phablet/dummyrunner:
---------------------------
#!/bin/bash
echo running $@
exec $@
---------------------------

usage: upstart-app-launch dummyrunner /path/to/executable

@Omer can you give the proposed wrapper a try

That did not work for me, but QT_QPA_PLATFORM=minimal is working fine since then.
