Automated Regression Testing with Splinter and Jupyter

Jace Browning

https://pyohio.org/2018/schedule/pres...

This talk will start with a background on testing and quality assurance:

Terminology
Unit vs. Integration vs. System (end-to-end)
Automated vs. Exploratory

Goals of end-to-end testing
Test production server configurations
Test JavaScript engines in browsers
Responsiveness/visual testing
External API hookups

The next section will outline a layered approach for writing end-to-end tests with each step building on the last:

Selenium basics
Language bindings (Python examples)
Sequential test scripts
Adopting the “Page Object Model”
Using a WebDriver API wrapper (Splinter examples)
Helper functions to enable automated exploratory testing

Before the final section, there will be a demo of the previous examples run against a live website.

The final section will recommend an approach to building tests against your own site:

Alternatives
Dogfooding
Beta testers
Manual testers

Make your site testable
Name your forms and fields
Accessible sites are testable sites
Test mode for account signups
Expose internal state when possible
Allow “cheats” on your staging server

Writing tests
Start with under-tested, high-risk features
Make your bot users identifiable for easy cleanup
Run your tests every time you deploy
Incorporate logging, screenshots, and reports
