Testing Strategies for a Compiler-Driven Full-Stack Web Framework

Summary

This article provides an in-depth look at how Wasp, a compiler-driven full-stack web framework, approaches testing across its complex architecture. The framework generates complete source code from configuration and logic files, creating multiple layers that can fail in unique ways. The article covers practical testing strategies including unit tests, integration tests, end-to-end tests, and snapshot testing, with specific examples of how they test different components like the compiler, generated code, and database operations. It emphasizes the importance of automated testing for maintaining stability in a complex system where traditional testing approaches may not suffice.
