coverage-py

filter

A list of Python modules or filesystem paths to use in the coverage report, e.g. `['helloworld_test', 'helloworld/util/dirutil'].

Both modules and directory paths are recursive: any submodules or child paths, respectively, will be included.

If you leave this off, the coverage report will include every file in the transitive closure of the address/file arguments; for example, test :: will include every Python file in your project, whereas test project/app_test.py will include app_test.py and any of its transitive dependencies.

report

[
  "console"
]

Which coverage report type(s) to emit.

global_report

If true, Pants will generate a global coverage report.

The global report will include all Python source files in the workspace and not just those depended on by the tests that were run.

version

Requirement string for the tool.

extra_requirements

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.

interpreter_constraints

[
  "CPython>=3.6,<4"
]

Python interpreter constraints for this tool.

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-setup].invalid_lockfile_behavior). See https://github.com/pantsbuild/pants/blob/release_2.7.1rc1/src/python/pants/backend/python/subsystems/coverage_py_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=coverage-py.

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-setup].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.

output_dir

Path to write the Pytest Coverage report to. Must be relative to build root.

config

Path to an INI or TOML config file understood by coverage.py (https://coverage.readthedocs.io/en/stable/config.html).

Setting this option will disable [coverage-py].config_discovery. Use this option if the config is located in a non-standard location.

config_discovery

If true, Pants will include any relevant config files during runs (.coveragerc, setup.cfg, tox.ini, and pyproject.toml).

Use [coverage-py].config instead if your config is in a non-standard location.
