python_test_utils
Generate a python_source target for each file in the sources field.
This target generator is intended for test utility files like conftest.py, although it behaves identically to the python_sources target generator and you can safely use that instead. This target only exists to help you better model and keep separate test support files vs. production files.

dependencies
Iterable[str] | NoneNoneAddresses to other targets that this target depends on, e.g. ['helloworld/subdir:lib', 'helloworld/main.py:lib', '3rdparty:reqs#django'].
This augments any dependencies inferred by Pants, such as by analyzing your imports. Use ./pants dependencies or ./pants peek on this target to get the final result.
See https://www.pantsbuild.org/v2.9/docs/targets#target-addresses and https://www.pantsbuild.org/v2.9/docs/targets#target-generation for more about how addresses are formed, including for generated targets. You can also run ./pants list :: to find all addresses in your project, or ./pants list dir: to find all addresses defined in that directory.
If the target is in the same BUILD file, you can leave off the BUILD file path, e.g. :tgt instead of helloworld/subdir:tgt. For generated first-party addresses, use ./ for the file path, e.g. ./main.py:tgt; for all other generated targets, use :tgt#generated_name.
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 | NoneNoneA human-readable description of the target.
Use ./pants list --documented :: to see all targets with descriptions.
interpreter_constraints
Iterable[str] | NoneNoneThe Python interpreters this code is compatible with.
Each element should be written in pip-style format, e.g. CPython==2.7.* or CPython>=3.6,<4. You can leave off CPython as a shorthand, e.g. >=2.7 will be expanded to CPython>=2.7.
Specify more than one element to OR the constraints, e.g. ['PyPy==3.7.*', 'CPython==3.7.*'] means either PyPy 3.7 or CPython 3.7.
If the field is not set, it will default to the option [python].interpreter_constraints.
See https://www.pantsbuild.org/v2.9/docs/python-interpreter-compatibility for how these interpreter constraints are merged with the constraints of dependencies.
overrides
Dict[Union[str, Tuple[str, ...]], Dict[str, Any]] | NoneNoneOverride the field values for generated python_source targets.
Expects a dictionary of relative file paths and globs to a dictionary for the overrides. You may either use a string for a single path / glob, or a string tuple for multiple paths / globs. Each override is a dictionary of field names to the overridden value.
For example:
overrides={
"foo.py": {"skip_pylint": True]},
"bar.py": {"skip_flake8": True]},
("foo.py", "bar.py"): {"tags": ["linter_disabled"]},
}
File paths and globs are relative to the BUILD file's directory. Every overridden file is validated to belong to this target's sources field.
If you'd like to override a field's value for every python_source target generated by this target, change the field directly on this target rather than using the overrides field.
You can specify the same file name in multiple keys, so long as you don't override the same field more than one time for the file.
skip_autoflake
boolFalseIf true, don't run Autoflake on this target's code.
skip_bandit
boolFalseIf true, don't run Bandit on this target's code.
skip_black
boolFalseIf true, don't run Black on this target's code.
skip_docformatter
boolFalseIf true, don't run Docformatter on this target's code.
skip_flake8
boolFalseIf true, don't run Flake8 on this target's code.
skip_isort
boolFalseIf true, don't run isort on this target's code.
skip_mypy
boolFalseIf true, don't run MyPy on this target's code.
skip_pylint
boolFalseIf true, don't run Pylint on this target's code.
skip_pyupgrade
boolFalseIf true, don't run pyupgrade on this target's code.
skip_yapf
boolFalseIf true, don't run yapf on this target's code.
sources
Iterable[str] | None('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.ext', 'test_*.ext', '!test_ignore.ext'].
tags
Iterable[str] | NoneNoneArbitrary strings to describe a target.
For example, you may tag some test targets with 'integration_test' so that you could run ./pants --tag='integration_test' test :: to only run on targets with that tag.
