python_tests

Generate a `python_test` target for each file in the `sources` field.
Backend: <span style="color: purple"><code>pants.backend.python</code></span>
## <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', '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 [Targets and BUILD files](🔗﻿) and [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.
## <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>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>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].resolves` to use.
If not defined, will default to `[python].default_resolve`.
All dependencies must share the same value for their `resolve` field.
## <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>
backend: <span style="color: green"><code>pants.backend.experimental.python.lint.autoflake</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>
backend: <span style="color: green"><code>pants.backend.python.lint.bandit</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>
backend: <span style="color: green"><code>pants.backend.python.lint.black</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>
backend: <span style="color: green"><code>pants.backend.python.lint.docformatter</code></span>

## <code>skip_isort</code>
<span style="color: purple">type: <code>bool</code></span>
<span style="color: green">default: <code>False</code></span>
backend: <span style="color: green"><code>pants.backend.python.lint.isort</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>

<span style="color: green">default: <code>False</code></span>
backend: <span style="color: green"><code>pants.backend.experimental.python.lint.pyupgrade</code></span>
If true, don't run pyupgrade 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>
backend: <span style="color: green"><code>pants.backend.python.lint.yapf</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.
If unset, will default to `[pytest].timeout_default`; if that option is also unset, then the test will never time out. Will never exceed `[pytest].timeout_maximum`. Only applies if the option `--pytest-timeouts` is set to true (the default).
