N2VC Testing

Preparation

Environment variables

The test currently requires some environment variables set in order to run, but these will be deprecated as soon as possible.

LXD

LXD should be installed via snap.

The connection to the LXD API server expects to use a self-signed SSL certificate, generated by lxc (lxc list, et al) is first one.

Juju

Juju is expected to be installed via snap and bootstrapped.

Run juju status -m controller and capture the IP address of machine 0. This is the Juju controller, specified in VCA_HOST

export VCA_HOST=1.2.3.4 export VCA_USER=admin export VCA_SECRET=admin

Running tests

Tests are written with pytest, driven by tox. All tests are run from the root directory of the repository.

Run one test

To run a single integration test, we tell tox which environment we need, and then the path to the test.

tox -e integration -- tests/integration/test_non-string_parameter.py

Running all tests

make test will invoke tox to run all unit tests. Alternatively, you can limit this to a specific type of test by invoking tox manually:

tox -e integration -- tests/integration/

TODO

  • Update CI environment to have Juju and LXD available via snap
  • Investigate running via Docker
  • Remove the requirement for setting environment variables
  • Integrate into Jenkins so that tests run against every commit
  • Add global timeout to abort tests that are hung
  • Only build a charm once per test run, i.e., if two or more tests use the same charm, we should only call charm build once.
