To run the tests simply run `make test`.
Some of the tests require certain environment variables to be set. `make` will
set the variables for you. In addition you can set the variables in your local
environment by running:
```shell
eval $(make -s env-vars)
```
This role uses molecule for testing. Each molecule test is called a scenario. To
list the scenarios defined for this role run `make list-scenarios`. You can run
a single scenario by running `make test-<scenario name>`.
Some tests rely on an environment variable, `MOLECULE_DOCKER_IMAGES`, to define
the platforms for the test. `MOLECULE_DOCKER_IMAGES` will get set automatically
by `make`, but can also be overridden by the user. `MOLECULE_DOCKER_IMAGES`
should be defined as a space separated list of docker images. The test will be
run all the images defined in `MOLECULE_DOCKER_IMAGES` in parallel. You can
control the parallelism of the test by setting `CONCURRENT_MOLECULE_PLATFORMS`
to the number of platforms you want to test at once. If
`CONCURRENT_MOLECULE_PLATFORMS` is less than the total number of
`MOLECULE_DOCKER_IMAGES` then the test will keep iterating over
`MOLECULE_DOCKER_IMAGES` `CONCURRENT_MOLECULE_PLATFORMS`-at-a-time until all
platforms have been tested.
### Vagrant Tests
All of the vagrant scenarios (tests) in this collection uses libvirt (KVM/QEMU)
for the hypervisor. We are unable to setup a KVM hypervisor in AWS for a
reasonable price. Therefore, if you want to run the vagrant scenarios you must
have access to a KVM hypervisor. In addition, for some of the tests you will
also need access to GitLab and Artifactory which may require the hypervisor be
connected to the AWS VPN.
