Pytest Duration Insights

This python package offers a small dashboard that helps you investigate long running pytest runs. It's built on top of the report that is generated by pytest-reportlog.

Preview

We're hosting a demo on GitHub pages. You can view it here. There's also an educational video announcement on calmcode.io found here.

Instructions.

1. Install.

pip install pytest-reportlog pytest-duration-insights

2. Make a report.

pytest --report-log reportlog.jsonl

3. Explore!

pytest-duration-insights explore reportlog.jsonl

This will start up a service that tries to help you find areas in your testing code base that are worth investigating.

Parametrized Tests

This tool automatically hides the parametrized test results. But if these are very important to you then you can turn them on via the --no-trim flag.

pytest-duration-insights explore --no-trim reportlog.jsonl

Be aware that you might get very dense visuals when you do this.

Roadmap

We're only scratching the surface of what data we can visualise to help you speed up your pytest runs. Feedback is appreciated, especially if somebody has a keen insight that has helped in the past.

That said, this project is very much an experiment as well. See it as a tool you could try rather than a best practice.
