pytest_container
is a pytest <https://pytest.org>
_ plugin
to test container images via pytest fixtures and testinfra <https://testinfra.readthedocs.io/en/latest/>
_. It takes care of all the boring
tasks, like spinning up containers, finding free ports and cleaning up after
tests, and allows you to focus on implementing the actual tests.
The plugin automates the following tasks:
Dockerfile
pytest_container
provides four fixtures that give you everything you need
for testing containers. Spinning up a container image can be as simple as
instantiating a Container
and parametrizing a test function with the
container
fixture:
.. code-block:: python
TW = Container(url="registry.opensuse.org/opensuse/tumbleweed:latest")
@pytest.mark.parametrize("container", [TW], indirect=["container"]) def test_etc_os_release_present(container: ContainerData): assert container.connection.file("/etc/os-release").exists
The fixture automatically pulls and spins up the container, stops it and removes
it after the test is completed. Your test function receives an instance of
ContainerData
with the ContainerData.connection
attribute. The
ContainerData.connection
attribute is a testinfra <https://testinfra.readthedocs.io/en/latest/>
_ connection object. It can be
used to run basic tests inside the container itself. For example, you can check
whether files are present, packages are installed, etc.
