How Airbnb migrated nearly 3.5K Enzyme test files to React Testing Library in just 6 weeks using automation and LLMs

Airbnb recently completed our first large-scale, LLM-driven code migration, updating nearly 3.5K React component test files from Enzyme to use React Testing Library (RTL) instead. We’d originally estimated this would take 1.5 years of engineering time to do by hand, but — using a combination of frontier models and robust automation — we finished the entire migration in just 6 weeks.

In this blog post, we’ll highlight the unique challenges we faced migrating from Enzyme to RTL, how LLMs excel at solving this particular type of challenge, and how we structured our migration tooling to run an LLM-driven migration at scale.

Clean Code Architecture

Hi everyone! In this handbook we're going to talk about writing "clean" code. It's a topic that used to confuse me a bit when I was starting out as a programmer.

So in this article we'll talk about what the term "clean code" means, why it's important, how can we assess whether a codebase is clean or not. You'll also learn some best practices and conventions you can follow to make your code cleaner.
