Workshop, 5×2h + Q&A • Wed & Thu, August 19 – September 3 2020
09:00 – 11:30 AM PDT (Pacific Daylight Time)

Browser automation helps us create resilient web applications by ensuring they are battle-tested through end-to-end tests.

On the other end of the spectrum, they also help create a whole new field of websites and services, through techniques such as browser scraping. In this workshop, you will learn browser automation from the ground up.

To get you fit for making full use of the benefits that browser automation brings along, we will cover:

End-to-end testing (with and without a testing library)
Scraping data from other websites and services
Automated performance, accessibility, and visual regression testing
Running automated browsers on free cloud services and a $5 VPS
Common pitfalls with browser automation and how to debug related automation issues.

Make your tests resilient: if every minor change causes your test to break, it is probably too brittle. In this workshop you'll learn how.

What Will We Explore In This Workshop?

Testing
End-to-end browser testing helps us create rock-solid web apps. Especially because you can validate certain website behavior which unit tests or integration tests will never catch. Learn common testing patterns, from user registration workflows (and email sending) to page interactivity and navigation.
Scraping
Believe it or not, entire startups are building their businesses around scraping web content. We’ll learn scraping strategies and how to operate fairly. As a fun exercise, we will produce an automated price checker that notifies us when an online product becomes cheaper.
Auditing
Testing is more than just asserting page titles. It’s ensuring you have no performance or accessibility regressions when you make changes to the code. Performance, accessibility, and even visual regression testing can be checked automatically. Learn the tools which can help you achieve this.
Personal productivity
How many of us have automated all those boring parts in their workflows? Very few, I suspect. That’s why we’ll look into strategies that help you become more productive — from filling in long web forms to dynamically creating images and even setting up your web development environment with automated browsers.
Deploying + Debugging
First, we’ll deploy our tests to the cloud. Test failures are inevitable, though, but with the right techniques, we can speed up the debugging process dramatically. DevTools and exporting screenshots and videos of our test run to see what went wrong are two of the approaches we’ll take a closer look at.

The closer you can get your test to match how people actually use your website in the real world, the more resilient your website will be.
