pytest_apiver

    

Pytest plugin helping to test packages implementing ApiVer.

Usage

Assuming your package exposes v1, v2, ... ApiVer interfaces, i.e. has structure like this:

my_package/
    __init__.py
    v1/
        __init__.py
    ...
    _v3/
        __init__.py

You can configure to run apiver-aware tests against it using pyproject.toml:

[tool.pytest.ini_options]
target_package_name = "my_package"

Then you can write tests like this:

@pytest.mark.apiver(from_ver=2, to_ver=3)
def test_run_for_apiver_ver_2_3(apiver_module):
    assert apiver_module.func()

Which will run test against my_package.v2.func() and my_package.v3.func() respectively.

For non-flat package structure, you can use auto-magical getter doing imports of submodules built into apiver_module fixture, e.g.:

@pytest.mark.apiver(from_ver=2, to_ver=2)
def test_func__v2(apiver_module):
    assert apiver_module.utils.func()  # equivalent to my_package.v2.utils.func()

Versioning

This package uses Semantic Versioning. TL;DR you are safe to use compatible release version specifier ~=MAJOR.MINOR in your pyproject.toml or requirements.txt.

Internal packages, i.e. prefixed by pytest_apiver._ do not share these guarantees and may change in a backwards-incompatible way at any time even in patch releases.

Development

Pre-requisites:

• pdm
• nox
• docker and docker compose plugin

Ideally, you should run nox -t format lint before every commit to ensure that the code is properly formatted and linted. Before submitting a PR, make sure that tests pass as well, you can do so using:

nox -t check # equivalent to `nox -t format lint test`

If you wish to install dependencies into .venv so your IDE can pick them up, you can do so using:

pdm install --dev

Release process

Run nox -s make_release -- X.Y.Z where X.Y.Z is the version you're releasing and follow the printed instructions.
