When a Necessary Evil becomes Indispensable: Testing in Production at Handshake

In a Test in Production MeetUp, Maria Verba, QA Automation Engineer at Handshake, discussed why and how her team tests in production. She emphasized the importance of having a healthy ecosystem for testing in production, including thorough tests, feature toggles, and monitoring. Maria also shared specific examples where testing in production is more beneficial than pre-production environments, such as performance testing with real-life traffic, using production data, and A/B testing and experimentation. Handshake uses LaunchDarkly to conduct experiments and A/B testing, which allows them to create records for additional conditions and configurations. The company plans to implement Canary testing in the future by diverting a portion of their traffic into new features.
