Add the testing required for neutron dynamic routing A.K.A dragent.
Create the zaza.charm_tests.dragent module for testing neutron dynamic
routing.
Create the zaza.configure module for reusable configuration tools.
Update utilities to simplify authenticating clients.
This change adds support for model specific overlays from
templates which are rendered at deploy time.
The overlay template directory will be searched for a corresponding
template (<bundle_name>.j2). If one is found then the overlay will
be rendered using environment variables matching AMULET* or
ZAZA_TEMPLATE* as a context. The rendered overlay will be used on
top of the specified bundle at deploy time.
A default overlay is always applied "local-charm-overlay.yaml". This
overlay is only used to move the location of the charm being deployed
to a relative path so the bundle can use "charm: <charm name>" rather
than "charm: ../../../<charm name>"
Bring over only those utilities required to run network_setup.py from
openstack-mojo-specs. These utilities have been generalized and python3
configured. Use libjuju whenever possible and pre-deprecate anything
else.
Add addition functions to the model.
The idea of this change is to put together helpers for including
functional tests for charms in a central location. The charm
declares the tests and bundles to be run to complete a
functional tests but the tests themselves live here in zaza.
To use this code the charm should have the following:
1) zaza in the test-requirements.txt
2) tox.ini should include a target like:
```
[testenv:func35]
basepython = python3
commands =
functest-bundle-deploy
```
3) Bundles which are to be used for the tests:
```
ls -1 tests/bundles/*
tests/bundles/xenial.yaml
```
4) A tests/tests.yaml file that describes the bundles to be run and
the tests
```
charm_name: vault
tests:
- zaza.charms_tests.vault.VaultTest
gate_bundles:
- xenial
dev_bundles:
- bionic
```
Tests can be run without running a deployment using functest-run-tests
with the list of test classes to be run:
```
functest-run-tests -t zaza.charms_tests.vault.VaultTest
```
Known Issues:
- The deploy_bundle and add_model methods should be using libjuju
- DEV_BUNDLES is currently ignored
- VaultUtils and VaultTest should probably be in separate files.
- When skipIfNotHA skips a test unittest does not pick up it has
been skipped
- A new model is created for each bundle even if an existing empty
model exists
- No model cleanup is performed.
