▶️ My A/B Testing Screw-ups
Let me show you how we've progressed over the past 3 years of running A/B Tests - starting from complete naivety, moving through frustration, and finally arriving at useful, practical knowledge (and some frustration). Learn with me how to avoid common blunders and conduct great experiments instead!

▶️ Mutation Testing: Testing your Tests
Most of us are probably familiar with code coverage. While we all love adding that 100% coverage badge in our repos, we should be aware that code coverage is limited in telling us how good our really tests are. How can we do better? Enter mutation testing!
Mutation testing is considered the gold standard for evaluating our tests' bug detection abilities and yet it's rather unknown in practise. In this talk, we'll explore the general concept, some of the reasons why it's rather a niche testing technique and then take a look at the tool(s) available in the JavaScript ecosystem.
We'll go through a live demo how to integrate the most popular MT tool (Stryker) into a JS project and I'll share my experience of using mutation testing at Sentry.

🙏 Sentry

Sentry is the market leader in the error monitoring space and like many startups with engineer founders, Sentry was born out of frustration with technology. David started Sentry as an open-source side project in 2008. We started in a small community — the Django web framework — and over time expanded our technology to support dozens of other platforms, including browser JavaScript and mobile applications.

Fast forward to today, we're a $90M Series E company with a $3B valuation and 200+ employees on a mission to help developers write better software faster, so we can get back to enjoying technology. As one can see, the adventure continues to be exciting as we bring our developer-first Application Monitoring to more customers and industries worldwide.
Consider us for the ride - We're hiring a JavaScript developer!
