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 or my_test_utils.py. Technically, it generates python_source targets in the exact same way as the python_sources target generator does, only that the sources field has a different default. So it is valid to use python_sources instead. However, this target can be helpful to better model your code by keeping separate test support files vs. production files.

Backend: pants.backend.python

`dependencies`

Iterable[str] | None

default: None

Addresses 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/2.21/docs/using-pants/key-concepts/targets-and-build-files 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 | None

default: None

A human-readable description of the target.

Use pants list --documented :: to see all targets with descriptions.

`interpreter_constraints`

Iterable[str] | None

default: None

The 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/2.21/docs/python/overview/interpreter-compatibility for how these interpreter constraints are merged with the constraints of dependencies.

`overrides`

Dict[Union[str, Tuple[str, ...]], Dict[str, Any]] | None

default: None

Override 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.

`resolve`

str | None

default: None

The resolve from [python].resolves to use.

If not defined, will default to [python].default_resolve.

All dependencies must share the same value for their resolve field.

`run_goal_use_sandbox`

bool | None

default: None

Whether to use a sandbox when running this target. Defaults to [python].default_run_goal_use_sandbox.

If true, runs of this target with the run goal will copy the needed first-party sources into a temporary sandbox and run from there.

Iterable[str] | None

default: ('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=['conftest.py', 'test_*.pyi', '*_test.pyi', 'tests.pyi']

`tags`

Iterable[str] | None

default: None

Arbitrary 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.
