coverage-py

Configuration for Python test coverage measurement.

Backend: ``

Config section: [coverage-py]

Basic options​

filter​

--coverage-py-filter="['<str>', '<str>', ...]"
PANTS_COVERAGE_PY_FILTER
pants.toml
[coverage-py]
filter = [
  '<str>',
  '<str>',
  ...,
]
default: []

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.

global_report​

--[no-]coverage-py-global-report
PANTS_COVERAGE_PY_GLOBAL_REPORT
pants.toml
[coverage-py]
global_report = <bool>
default: False

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.

report​

--coverage-py-report="[<CoverageReportType>, <CoverageReportType>, ...]"
PANTS_COVERAGE_PY_REPORT
pants.toml
[coverage-py]
report = [
  <CoverageReportType>,
  <CoverageReportType>,
  ...,
]
one of: console, xml, html, raw, json
default: 
[
  "console"
]

Which coverage report type(s) to emit.

Advanced options​

config​

--coverage-py-config=<file_option>
PANTS_COVERAGE_PY_CONFIG
pants.toml
[coverage-py]
config = <file_option>
default: None

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​

--[no-]coverage-py-config-discovery
PANTS_COVERAGE_PY_CONFIG_DISCOVERY
pants.toml
[coverage-py]
config_discovery = <bool>
default: True

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.

console_script​

--coverage-py-console-script=<str>
PANTS_COVERAGE_PY_CONSOLE_SCRIPT
pants.toml
[coverage-py]
console_script = <str>
default: coverage

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​

--coverage-py-entry-point=<str>
PANTS_COVERAGE_PY_ENTRY_POINT
pants.toml
[coverage-py]
entry_point = <str>
default: None

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.

extra_requirements​

--coverage-py-extra-requirements="['<str>', '<str>', ...]"
PANTS_COVERAGE_PY_EXTRA_REQUIREMENTS
pants.toml
[coverage-py]
extra_requirements = [
  '<str>',
  '<str>',
  ...,
]
default: []

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​

--coverage-py-interpreter-constraints="['<str>', '<str>', ...]"
PANTS_COVERAGE_PY_INTERPRETER_CONSTRAINTS
pants.toml
[coverage-py]
interpreter_constraints = [
  '<str>',
  '<str>',
  ...,
]
default: 
[
  "CPython>=3.6,<4"
]

Python interpreter constraints for this tool.

lockfile​

--coverage-py-lockfile=<str>
PANTS_COVERAGE_PY_LOCKFILE
pants.toml
[coverage-py]
lockfile = <str>
default: <default>

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_2.7.2/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'.

output_dir​

--coverage-py-output-dir=<str>
PANTS_COVERAGE_PY_OUTPUT_DIR
pants.toml
[coverage-py]
output_dir = <str>
default: dist/coverage/python

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

version​

--coverage-py-version=<str>
PANTS_COVERAGE_PY_VERSION
pants.toml
[coverage-py]
version = <str>
default: coverage[toml]>=5.5,<5.6

Requirement string for the tool.
