python_tests


Python tests.

These may be written in either Pytest-style or unittest style.

All test util code, other than conftest.py, should go into a dedicated python_library() target and then be included in the dependencies field.

See https://www.pantsbuild.org/docs/python-test-goal.

Backend: ``


compatibility

str | Iterable[str] | None
default: None

A string for Python interpreter constraints on this target. This should be written in Requirement-style format, e.g. CPython==2.7.* or CPython>=3.6,<4. As a shortcut, you can leave off CPython, e.g. >=2.7 will be expanded to CPython>=2.7. If this is left off, this will default to the option interpreter_constraints in the [python-setup] scope. See https://www.pantsbuild.org/docs/python-interpreter-compatibility.

dependencies

Iterable[str] | None
default: None

Addresses to other targets that this target depends on, e.g. ['helloworld/subdir:lib']. Alternatively, you may include file names. Pants will find which target owns that file, and create a new target from that which only includes the file in its sources field. For files relative to the current BUILD file, prefix with ./; otherwise, put the full path, e.g. ['./sibling.txt', 'resources/demo.json']. You may exclude dependencies by prefixing with !, e.g. ['!helloworld/subdir:lib', '!./sibling.txt']. Ignores are intended for false positives with dependency inference; otherwise, simply leave off the dependency from the BUILD file.

description

str | None
default: None

A human-readable description of the target. Use ./pants list --documented :: to see all targets with descriptions.

runtime_package_dependencies

Iterable[str] | None
default: None

Addresses to targets that can be built with the ./pants package goal and whose resulting assets should be included in the test run. Pants will build the assets as if you had run ./pants package. It will include the results in your archive using the same name they would normally have, but without the --distdir prefix (e.g. dist/). You can include anything that can be built by ./pants package, e.g. a pex_binary, python_awslambda, or an archive.

sources

Iterable[str] | None
default: ('test_*.py', '*_test.py', 'tests.py', 'conftest.py', 'test_*.pyi', '*_test.pyi', 'tests.pyi')

A list of files and globs that belong to this target. Paths are relative to the BUILD file's directory. You can ignore files/globs by prefixing them with !. Example: sources=['example.py', 'test_*.py', '!test_ignore.py'].

tags

Iterable[str] | None
default: None

Arbitrary strings that you can use to describe a target. For example, you may tag some test targets with 'integration_test' so that you could run ./pants --tags='integration_test' test :: to only run on targets with that tag.

timeout

int | None
default: None

A timeout (in seconds) which covers the total runtime of all tests in this target. This only applies if the option --pytest-timeouts is set to True.
