Generate a `python_test` target for each file in the `sources` field.

## <code>dependencies</code>

<span style="color: purple">type: <code>Iterable[str] | None</code></span> <span style="color: green">default: <code>None</code></span>

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.

## <code>description</code>

<span style="color: purple">type: <code>str | None</code></span> <span style="color: green">default: <code>None</code></span>

A human-readable description of the target.

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

## <code>experimental_resolve</code>

<span style="color: purple">type: <code>str | None</code></span> <span style="color: green">default: <code>None</code></span>

The resolve from `[python].experimental_resolves_to_lockfiles` to use, if any.

This field is highly experimental and may change without the normal deprecation policy.

## <code>extra_env_vars</code>

<span style="color: purple">type: <code>Iterable[str] | None</code></span> <span style="color: green">default: <code>None</code></span>

Additional environment variables to include in test processes. Entries are strings in the form `ENV_VAR=value` to use explicitly; or just `ENV_VAR` to copy the value of a variable in Pants's own environment. This will be merged with and override values from [test].extra_env_vars.

## <code>interpreter_constraints</code>

<span style="color: purple">type: <code>Iterable[str] | None</code></span> <span style="color: green">default: <code>None</code></span>

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 [Interpreter compatibility](🔗) for how these interpreter constraints are merged with the constraints of dependencies.

## <code>overrides</code>

<span style="color: purple">type: <code>Dict[Union[str, Tuple[str, ...]], Dict[str, Any]] | None</code></span> <span style="color: green">default: <code>None</code></span>

Override the field values for generated `python_test` 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:



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_test` 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.

## <code>runtime_package_dependencies</code>

<span style="color: purple">type: <code>Iterable[str] | None</code></span> <span style="color: green">default: <code>None</code></span>

Addresses to targets that can be built with the `./pants package` goal and whose resulting artifacts should be included in the test run.

Pants will build the artifacts as if you had run `./pants package`. It will include the results in your test's chroot, 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`.

## <code>skip_autoflake</code>

<span style="color: purple">type: <code>bool</code></span> <span style="color: green">default: <code>False</code></span>

If true, don't run Autoflake on this target's code.

## <code>skip_bandit</code>

<span style="color: purple">type: <code>bool</code></span> <span style="color: green">default: <code>False</code></span>

If true, don't run Bandit on this target's code.

## <code>skip_black</code>

<span style="color: purple">type: <code>bool</code></span> <span style="color: green">default: <code>False</code></span>

If true, don't run Black on this target's code.

## <code>skip_docformatter</code>

<span style="color: purple">type: <code>bool</code></span> <span style="color: green">default: <code>False</code></span>

If true, don't run Docformatter on this target's code.

## <code>skip_flake8</code>

<span style="color: purple">type: <code>bool</code></span> <span style="color: green">default: <code>False</code></span>

If true, don't run Flake8 on this target's code.

## <code>skip_isort</code>

<span style="color: purple">type: <code>bool</code></span> <span style="color: green">default: <code>False</code></span>

If true, don't run isort on this target's code.

## <code>skip_mypy</code>

<span style="color: purple">type: <code>bool</code></span> <span style="color: green">default: <code>False</code></span>

If true, don't run MyPy on this target's code.

## <code>skip_pylint</code>

<span style="color: purple">type: <code>bool</code></span> <span style="color: green">default: <code>False</code></span>

If true, don't run Pylint on this target's code.

## <code>skip_tests</code>

<span style="color: purple">type: <code>bool</code></span> <span style="color: green">default: <code>False</code></span>

If true, don't run this target's tests.

## <code>skip_yapf</code>

<span style="color: purple">type: <code>bool</code></span> <span style="color: green">default: <code>False</code></span>

If true, don't run yapf on this target's code.

## <code>sources</code>

<span style="color: purple">type: <code>Iterable[str] | None</code></span> <span style="color: green">default: <code>('test_*.py', '*_test.py', 'tests.py')</code></span>

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']`.

## <code>tags</code>

<span style="color: purple">type: <code>Iterable[str] | None</code></span> <span style="color: green">default: <code>None</code></span>

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.

## <code>timeout</code>

<span style="color: purple">type: <code>int | None</code></span> <span style="color: green">default: <code>None</code></span>

A timeout (in seconds) used by each test file belonging to this target.

This only applies if the option `--pytest-timeouts` is set to True.
