adt-run does not work with autopilot on emulator

[Richard Huddie]

When trying to run autopilot tests (lp:ubuntu-sanity-tests) on the ubuntu emulator, the test fails with the following error. If the autopilot tests are installed and run directly on the emulator, they will work ok. This problem only happens when trying to use adt-run:

Adding emulator environment details:

current build number: 90

Hm, I'm on almost the same version:

current build number: 92
device name: generic_x86
channel: ubuntu-touch/devel-proposed
alias: ubuntu-touch/vivid-proposed
last update: 2015-02-05 03:25:51

I ran the tests like this:
bzr branch lp:ubuntu-sanity-tests
adt-run --setup-commands 'mount -o remount,ro /' -B ubuntu-sanity-tests// --- ssh -s adb

but they fail with something completely different:

When I run them on an r/w image so that the test dependencies actually get installed with apt, this now fails with

adt-run [08:20:02]: test sanity: [-----------------------
Traceback (most recent call last):
  File "/tmp/adt-run.qsFTLT/build.sGK/real-tree/debian/tests/sanity", line 23, in <module>
    from ubuntu_sanity_tests import sanity
ImportError: No module named 'ubuntu_sanity_tests'

because it doesn't set PYTHONPATH=. anywhere, and the binary is in debian/tests/. That's another reason why they currently can't work runnning from the tree instead of from the package. I fixed that with http://paste.ubuntu.com/10068247/ and now the tests actually do run. So I recommend applying this patch to lp:ubuntu-sanity-tests. The tests fail with

adt-run [08:31:10]: test sanity: - - - - - - - - - - results - - - - - - - - - -

But I did see quite some windows flying around; not sure what the sudo thingy is, presumably the config.py device_password key doesn't default to 0000?

But that still leaves me with not being able to reproduce your original crash. Can you please tell me the precise steps and commands that you did to get the /dev/uinput issue?

[Martin Pitt (pitti)]

Indeed I don't get the weird error message from comment 2 with chmod 666 /dev/uinput. Can you confirm that this works for you on a fresh emulator?

  adt-run --setup-commands 'mount -o remount,ro /; chmod 666 /dev/uinput' -B ubuntu-sanity-tests// --- ssh -s adb

This unpacks the test deps and starts running the tests here, and just fails due to the sudo password problem.

[Martin Pitt (pitti)]

This should be fixed with http://anonscm.debian.org/cgit/autopkgtest/autopkgtest.git/commit/?id=18a4492f0bc , it works for me with that. Can you confirm? You can either download http://anonscm.debian.org/cgit/autopkgtest/autopkgtest.git/plain/runner/adt-run and install it in /usr/bin/, or checkout git and call ./run-from-checkout instead of adt-run.

This bug was fixed in the package autopkgtest - 3.9.5git1

---------------
autopkgtest (3.9.5git1) vivid; urgency=medium

    available.
