The vmtests are a suite of tests which verify that noisicaä is compatible with the officially supported set of distributions.

The tests run under virtualbox, install a minimal version of each distribution, build noisicaä from source and then run the test suite.


Before you can run test vmtests, you might have to install some additional packages:

pip install $(./listdeps --pip --vmtests)
sudo apt install $(./listdeps --system --vmtests)

The VMs are stored in a vmtests directory. That directory will contain some large files, so if you don't want those to be place in your home directory (e.g. because it's hosted on a NFS server, you don't want to waste precious space on your SSD, etc.), you can create it as a symlink to some suitable place.

mkdir /path/to/vmtests
ln -s /path/to/vmtests vmtests

Running the tests

python -m noisidev.runvmtests
  • Each distribution runs in a separate VM.

  • Distributions are named $DIST-$RELEASE, e.g. ubuntu-16.04.

  • When no argument is given, tests for all supported distributions are run. You can restrict the tests by listing the desired distributions as arguments:

python -m noisidev.runvmtests ubuntu-16.04
  • Once a the distribution has been installed in a VM, a snapshot called 'clean' is created. On subsequent runs that snapshot gets restored, so the tests always run from the same state. If you just want to retry a test without reverting to the clean state, use --clean-snapshot=false.

  • If you want to reinstall the VMs from scratch, use --rebuild-vm=true.

Debugging test failures

If inspecting the output is not sufficient to pin down the problem, you can restart the VM in the state as it was after the test finished:

python -m noisidev.runvmtests --just-start $DISTNAME
