bug#26211: [PATCH] gnu: networkmanager-qt: Disable a failing test.

[Ludovic Courtès]

Hi Hartmut,

Hartmut Goebel <address@hidden> skribis:

> The error-message was: "D-Bus library appears to be incorrectly set up;
> failed to read machine uuid: Failed to open '/etc/machine-id':
> No such file or directory".

The output is:

--8<---------------cut here---------------start------------->8---
starting phase `check'
process 2014: D-Bus library appears to be incorrectly set up; failed to read 
machine uuid: Failed to open "/etc/machine-id": No such file or directory
See the manual page for dbus-uuidgen to correct this issue.
Test project /tmp/guix-build-networkmanager-qt-5.28.0.drv-0/build

96% tests passed, 1 tests failed out of 25

Total Test time (real) =   0.97 sec

The following tests FAILED:
          3 - activeconnectiontest (Failed)
Errors while running CTest
phase `check' failed after 1.0 seconds
--8<---------------cut here---------------end--------------->8---

So the failure is the ‘activeconnectiontest’ test, not the D-Bus thing.
Outside the chroot build environment (and outside of ‘guix environment
-C’), this test passes.

When running “ctest --verbose”, we see:

We can get more details as explained at
<http://doc.qt.io/qt-5/qtest-overview.html> by running:

  dbus-launch 
/tmp/guix-build-networkmanager-qt-5.28.0.drv-0/build/autotests/activeconnectiontest
 -vs

That didn’t really help me though.  The strace output shows nothing
obvious either (such uses code looking for actual network interfaces via
/proc/net/dev or using ioctls); it seems the code has complete mocks for
network interfaces and shouldn’t depend on the real network interfaces.

Could be maybe seek advice from upstream?

HTH,
Ludo’.
