Contributing Galata (JupyterLab UI Testing & Automation Framework)

[mbektas]

Hi everyone, on June 17^th I had presented Galata at weekly dev meeting and there was very positive feedback from core developers. We as Bloomberg are interested in contributing this project to JupyterLab organization, and continue helping its development. We are ready to switch the repo over. What are the next steps in this process? Please let us know.

A brief overview of Galata:

Galata is a UI testing and automation framework custom built for JupyterLab.

• uses headless Chrome to launch JupyterLab
• uses puppeteer to interact with browser
• comes with a high level API to interact with JupyterLab UI effortlessly
• provides testing, capturing and comparison tools
• comes with a built-in HTML report generator for test results
• comes with a built-in http server to serve test reports
• comes with a command line interface to manage tests, configuration and many other tasks

Main use cases

• Visual regression testing of JupyterLab UI components, notebook widget rendering
• Automating end-to-end UI testing
• Automating notebook execution for output capture & inspect

whoah! that's awesome! I tend to use the UI testing framework of "demo it locally and then close my eyes and send it to production what's the worst that could happen?" This sounds more rigorous than that :-)

Fantastic, thanks @mbektasbbg! The steps are outlined in our Readme

This is amazing work - I am strongly in favor of JupyterLab incorporating this repo

I'd be remiss to not mention robot framework here: https://robotframework.org I've been using it extensively on open source and day job stuff. I haven't looked over Galata, but from my experience, some differences from the above bullet points: - tests are written in plain English-ish (humorous, as it's a _very_ international community) - works with multiple browsers - python/selenium powered - doesn't download random browser binaries from the internet - does not use nodejs anywhere - has some of the best reporting I've used - can do _far more_ than "just" browser testing (I've spun up whole hubs with it under test) We've been putting some of our goodies here for jupyter-specific stuff: https://github.com/robots-from-jupyter

Is there a repo for Galata to learn more? Or is it closed-source at the moment?

Thanks @blink1073 , will check it out.

yes @krassowski, it is closed-source at the moment.

@bollwyvl thanks for sharing about robot, I will look into it. I need to learn more about robot to provide proper comparison but Galata's main advantage over it would be the deep and low level interaction with JupyterLab since it is custom-built for JupyterLab.

I would love it to be elected as a Jupyter subproject.
