Vitest Testing Patterns

You're writing tests with Vitest and React Testing Library, and this gives you the patterns to do it right. It covers the practical stuff: mocking API routes and database calls, testing React components with user interactions, handling chained mocks for Drizzle ORM, and organizing test files in a Next.js project. The examples show real scenarios like authentication checks, error states, and timer mocking. It's opinionated about file structure and pairs well with E2E testing skills since unit tests are just one layer. If you're already using Vitest but keep googling how to mock that one thing, this consolidates those patterns in one place.
