pytest

args

Arguments to pass directly to Pytest, e.g. --pytest-args="-k test_foo --quiet"

timeouts

Enable test target timeouts. If timeouts are enabled then test targets with a timeout= parameter set on their target will time out after the given number of seconds if not completed. If no timeout is set, then either the default timeout is used or no timeout is configured.

version

Requirement string for the tool.

extra_requirements

[
  "pytest-cov>=2.12,!=2.12.1,<3.1"
]

Any additional requirement strings to use with the tool. This is useful if the tool allows you to install plugins or if you need to constrain a dependency to a certain version.

lockfile

Path to a lockfile used for installing the tool.

Set to the string <default> to use a lockfile provided by Pants, so long as you have not changed the --version and --extra-requirements options, and the tool's interpreter constraints are compatible with the default. Pants will error or warn if the lockfile is not compatible (controlled by [python].invalid_lockfile_behavior). See https://github.com/pantsbuild/pants/blob/release_2.9.0/src/python/pants/backend/python/subsystems/pytest_lockfile.txt for the default lockfile contents.

Set to the string <none> to opt out of using a lockfile. We do not recommend this, though, as lockfiles are essential for reproducible builds.

To use a custom lockfile, set this option to a file path relative to the build root, then run ./pants generate-lockfiles --resolve=pytest.

Lockfile generation currently does not wire up the [python-repos] options. If lockfile generation fails, you can manually generate a lockfile, such as by using pip-compile or pip freeze. Set this option to the path to your manually generated lockfile. When manually maintaining lockfiles, set [python].invalid_lockfile_behavior = 'ignore'.

console_script

The console script for the tool. Using this option is generally preferable to (and mutually exclusive with) specifying an --entry-point since console script names have a higher expectation of staying stable across releases of the tool. Usually, you will not want to change this from the default.

entry_point

The entry point for the tool. Generally you only want to use this option if the tool does not offer a --console-script (which this option is mutually exclusive with). Usually, you will not want to change this from the default.

timeout_default

The default timeout (in seconds) for a test target if the timeout field is not set on the target.

timeout_maximum

The maximum timeout (in seconds) that may be used on a python_tests target.

junit_family

The format of generated junit XML files. See https://docs.pytest.org/en/latest/reference.html#confval-junit_family.

execution_slot_var

If a non-empty string, the process execution slot id (an integer) will be exposed to tests under this environment variable name.

config_discovery

If true, Pants will include all relevant Pytest config files (e.g. pytest.ini) during runs. See https://docs.pytest.org/en/stable/customize.html#finding-the-rootdir for where config files should be located for Pytest to discover them.
