swarmauri_tests_readme_examples 0.1.2

Pytest plugin that executes README code examples.

---

Overview

swarmauri_tests_readme_examples is a pytest plugin that turns Markdown code blocks into executable tests. It scans README (or other documentation) files for Python examples and verifies that every runnable block still executes successfully. This keeps documentation trustworthy without hand-maintained test_readme_example.py scaffolding.

The plugin works out of the box for Python code blocks (```python, ```py, ```pycon) and exposes command-line flags and pyproject.toml settings so you can fine-tune which files and languages are exercised.

Installation

pip install swarmauri_tests_readme_examples

pytest discovers the plugin automatically after installation.

Quick Start

Run pytest as usual to execute every Python code block in README.md:

pytest

Sample failure output:

E   README.md::block-3 raised ValueError('boom')

Configuration

You can control the scan through CLI options or pyproject.toml:

• --readme-files – comma/newline separated Markdown files (default: README.md)
• --readme-languages – languages to execute (default: python, py, pycon)
• --readme-mode – parameterized (default) or aggregate
• --readme-skip-markers – comment markers that skip a block when they appear on the first non-empty line

pyproject.toml example (under [tool.pytest.ini_options]):

[tool.pytest.ini_options]
readme_files = """
    README.md
    docs/guide.md
"""
readme_languages = """
    python
    py
"""
readme_mode = "aggregate"
readme_skip_markers = """
    # pytest: skip-example
    # docs: skip
"""

Skipping Blocks

Place one of the configured skip markers on the first non-empty line to leave a code block out of execution:

```python
# pytest: skip-example
print("shown in docs, ignored in tests")
```

Aggregate Mode

Switch to --readme-mode=aggregate (or set readme_mode = "aggregate") to collapse all README checks into a single pytest item that aggregates every failure message. This is handy when you want a brief summary rather than many individual tests.
