## Overview

`swarmauri_tests_pylicense` is a [pytest](https://docs.pytest.org/) plugin that
scans a package's full dependency tree and ensures each dependency declares a
license. The plugin resolves dependencies recursively, checking every
transitive requirement. It inspects both the `License` metadata field and
any `Classifier` entries that declare a license.

By default, the plugin runs in *parameterized* mode which creates one test per
dependency. An *aggregate* mode is also available that reports all missing
licenses in a single test.

## Installation

```bash
pip install swarmauri_tests_pylicense
```

`pytest` automatically discovers the plugin once it is installed.

## Usage

### Parameterized (default)

Run `pytest` with the package name to scan its dependency licenses:

```bash
pytest --pylicense-package=<your-package>
```

Each generated test encodes the full dependency path, the resolved version,
and the detected license of the terminal package. For example:

```
swarmauri_tests_pylicense:license::pkg::depA::depB==1.2.3 [Apache-2.0]
```

### Aggregate

Use the `--pylicense-mode=aggregate` flag to consolidate checks into one test:

```bash
pytest --pylicense-package=<your-package> --pylicense-mode=aggregate
```

### Allow and Disallow Lists

To restrict acceptable licenses, provide a comma-separated allow list or
disallow list. These can be passed via command-line options or environment
variables.

Command-line:

```bash
pytest --pylicense-package=<your-package> --pylicense-allow-list=MIT,Apache-2.0
pytest --pylicense-package=<your-package> --pylicense-disallow-list=GPL
```

Environment variables:

```bash
export PYLICENSE_ALLOW_LIST="MIT,Apache-2.0"
export PYLICENSE_DISALLOW_LIST="GPL"
pytest --pylicense-package=<your-package>
```

If both are provided, any license not in the allow list or explicitly present
in the disallow list will cause a test failure. By default, all licenses are
allowed and none are disallowed.

### Accepting Specific Dependencies

Some transitive dependencies may ship with unusual or proprietary licenses that
are acceptable for your project. Use `--pylicense-accept-deps` (or the
`PYLICENSE_ACCEPT_DEPS` environment variable) with a comma-separated list to
explicitly bypass those packages. For example:

```bash
pytest --pylicense-package=<your-package> --pylicense-accept-deps=cffi
```

This tells the plugin to treat `cffi` as pre-approved. Any license issues for
`cffi`—including unknown or non-standard licenses—are ignored while other
dependencies continue to be validated normally.
