Wasp is a compiler-driven full-stack web framework that generates complete source code for web apps, combining React, Node.js, and Prisma with a Rails-like experience. The team emphasizes rigorous, readable automated testing across all layers, from the compiler to generated apps, to maintain reliability and developer confidence.

Why it matters: Thorough testing ensures Wasp’s code generation and features work reliably, reducing bugs in complex full-stack app development.

The big picture: Wasp integrates compiler-driven code generation with testing strategies like snapshot tests, end-to-end tests, and documentation verification to improve developer experience.

Quick takeaway: Their testing includes verifying generated code changes, runtime behavior, deployment, and even documentation examples to keep everything consistent and trustworthy.

Commenters say: Many highlight challenges new languages face with limited LLM training data, stressing the need for strong tooling and examples, while noting Wasp’s approach aligns with long-standing ideas like Opalang and Ur/Web.
