toolbox/test/system

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.

Warning: The tests are not executed in an isolated environment. Running the tests will clear all podman state (delete all containers, images, etc).

Dependencies

• awk
• bats
• GNU coreutils
• podman
• skopeo
• toolbox

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.

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"

• 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() and teardown() functions for that purpose.

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.
