Bill Sorensen shares an open-source library he authored called tzientist. It's a "Scientist-like library for Node.js, implemented in TypeScript. It permits comparing legacy and refactored code paths in production environments, verifying both functional and non-functional requirements. This is also known as the Parallel Run pattern."

Bill goes into what inspired him to author the library, what it's been like to maintain it, and why you should consider using it if traditional testing strategies won't handle the refactoring you're trying to do.

Courtney Adams and Dave Lyzenga, Software Engineers in Test, discuss testing processes as part of product development. They talk about their experiences with different products and frameworks. They also cover the Testing Pyramid, cross-browser and cross-operating-system testing, how to define Acceptance Criteria (AC) for success.

Dan Kryzanowski, our resident NextJS expert, discusses what goes into developing an enterprise-level application using this React fullstack framework. He talks about the developer-experience enhancements that he and his team made which led to a successful release on a tight deadline and some outstanding resulting metrics.

“Know your tools - use an interactive debugger. Your brain isn’t a compiler - stop trying to interpret code by reading it.” ~Matt Schick, Lead Engineer at JellyvisionWhat is legacy code? Should you rewrite your legacy app to use microservices? The answers may surprise you.

Hosts Nana and Dave ask Matt about legacy app maintenance, developer archetypes (investigators vs creators), the “strangler pattern,” monolith designs, and more. Matt goes into tradeoffs, boundaries, hairy migrations, debugging, testing, clean code, and perhaps most importantly, “leaving your legacy.”
