# Integration Tests
|
|
|
|
lorax uses Cockpit's integration test framework and infrastructure. To do this,
|
|
we're checking out Cockpit's `bots/` subdirectory. It contains links to test
|
|
images and tools to manipulate and start virtual machines from them.
|
|
|
|
Each test is run on a new instance of a virtual machine.
|
|
Branch/test matrix is configured in `bots/tests-scan` inside the
|
|
[cockpit repository](https://github.com/cockpit-project/cockpit).
|
|
|
|
## Dependencies
|
|
|
|
These dependencies are needed on Fedora to run tests locally:
|
|
|
|
$ sudo dnf install curl expect \
|
|
libvirt libvirt-client libvirt-daemon libvirt-python \
|
|
python python-libguestfs python-lxml libguestfs-xfs \
|
|
python3 libvirt-python3 \
|
|
libguestfs-tools qemu qemu-kvm rpm-build rsync xz
|
|
|
|
## Building a test VM
|
|
|
|
To build a test VM, run
|
|
|
|
$ make vm
|
|
|
|
This downloads a base image from Cockpit's infrastructure. You can control
|
|
which image is downloaded with the `TEST_OS` environment variable. Cockpit's
|
|
[documentation](https://github.com/cockpit-project/cockpit/blob/master/test/README.md#test-configuration)
|
|
lists accepted values. It then creates a new image based on that (a qemu
|
|
snapshot) in `tests/images`, which contain the current `tests/` directory and
|
|
have newly built rpms from the current checkout installed.
|
|
|
|
To delete the generated image, run
|
|
|
|
$ make vm-reset
|
|
|
|
Base images are stored in `bots/images`. Set `TEST_DATA` to override this
|
|
directory.
|
|
|
|
## Running tests
|
|
|
|
After building a test image, run
|
|
|
|
$ ./test/check-cli [TESTNAME]
|
|
|
|
or any of the other `check-*` scripts. To debug a test failure, pass `--sit`.
|
|
This will keep the test machine running after the first failure and print an
|
|
ssh line to connect to it.
|
|
|
|
Run `make vm` after changing tests or lorax source to recreate the test
|
|
machine. It is usually not necessary to reset the VM.
|
|
|
|
## Updating images
|
|
|
|
The `bots/` directory is checked out from Cockpit when `make vm` is first run.
|
|
To get the latest images you need to update it manually (in order not to poll
|
|
GitHub every time):
|
|
|
|
$ make -B bots
|
