The 000-setup.bats and 999-teardown.bats files were added [1] at a time
when Bats didn't offer any hooks for suite-wide setup and teardown.
That changed in Bats 1.7.0, which introduced the setup_suite and
teardown_suite hooks. These hooks make it easier to run a subset of the
tests, which is a good thing.
In the past, to run a subset of the tests, one had to do:
$ bats ./test/system/000-setup.bats ./test/system/002-help.bats \
./test/system/999-teardown.bats
Now, one only has to do:
$ bats ./test/system/002-help.bats

System tests
These tests are built with BATS (Bash Automated Testing System).
The tests are meant to ensure that Toolbox's functionality remains stable throughout updates of both Toolbox and Podman/libpod.
The tests are set up in a way that does not affect the host environment. Running them won't remove any existing containers or images.
Dependencies
awkbatsGNU coreutilshttpd-toolsopensslpodmanskopeotoolbox
These tests use a few standard libraries for bats which help with clarity
and consistency. The libraries are bats-support
and bats-assert. These libraries are
provided as git submodules in the libs directory. Make sure both are present.
How to run the tests
First, make sure you have all the dependencies installed.
- Enter the toolbox root folder
- Invoke command
bats ./test/system/and the test suite should fire up
Mocking of images is done automatically to prevent potential networking issues and to speed up the cases.
By default the test suite uses the system versions of podman, skopeo and
toolbox.
If you have a podman, skopeo or toolbox installed in a nonstandard
location then you can use the PODMAN, SKOPEO and TOOLBOX environmental
variables to set the path to the binaries. So the command to invoke the test
suite could look something like this: PODMAN=/usr/libexec/podman TOOLBOX=./toolbox bats ./test/system/.
When running the tests, make sure the test suite: [job] jobs are successful.
These jobs set up the whole environment and are a strict requirement for other
jobs to run correctly.
Writing tests
Environmental variables
- Inspect top part of
libs/helpers.batsfor a list of helper environmental variables
Naming convention
- All tests should follow the nomenclature:
[command]: <test description>... - When the test is expected to fail, start the test description with "Try to..."
- When the test is to give a non obvious output, it should be put in parenthesis at the end of the title
Examples:
@test "create: Create the default container"@test "rm: Try to remove a non-existent container"
Test case environment
- All the tests start with a clean system (no images or containers) to make sure
that there are no dependencies between tests and they are really isolated. Use
the
setup()andteardown()functions for that purpose.
Image registry
-
The system tests set up an OCI image registry for testing purposes -
localhost:50000. The registry requires authentication. There is one account present:user(password:user) -
The registry contains by default only one image:
fedora-toolbox:34
Example pull of the fedora-toolbox:34 image:
$PODMAN login --username user --password user "$DOCKER_REG_URI"
$PODMAN pull "$DOCKER_REG_URI/fedora-toolbox:34"
