Testing Strategies for Modern Web Apps: What Actually Works

Most teams write tests primarily to avoid regressions. That's valid — but it misses the deeper value. A well-designed test suite forces you to write modular, decoupled code. It makes refactoring safe. It documents intended behavior more honestly than comments ever do.

The trouble is that poor testing strategies produce test suites that are slow, brittle, and provide false confidence. This guide is about building the right coverage — the kind that catches real bugs without fighting you at every merge.
