> The [Arvados CWL Tester library](https://github.com/arvados/arvados_cwl_tester) is dedicated to people that develop pipelines in CWL and run them on Arvados. It allows you to create easy and reproducible tests for CWL scripts, which you can keep in your repository inside a Python script and run them using the `pytest` package from Python.
