Node+JS Interactive

This talk will look into solutions to automatically capture and assert the performance as part of your functional tests using WebDriver and Chrome DevTools technologies. By looking into the workflow of a browser driver, you will learn not only how a WebDriver actually automates web pages, you will also get insights on how you need to tweak this setup to start capturing live tracing data from the browser.

Analyzing the performance of a web application is hard and can’t be done by just looking at the raw captured data. Therefore you will learn how tracing data is structured and which Node.js tools you can use to compute the important user experience metrics out of it. With this knowledge, you will be able to ensure that your PWA stays within your defined performance budget every time you run your end-to-end test in CI/CD.
