Unit Testing tRPC Procedures
Learn to write isolated unit tests for individual tRPC procedures using popular testing frameworks.
Unit Testing tRPC Procedures
Welcome! In this lesson, we'll dive into unit testing for tRPC. Unit testing focuses on verifying individual, isolated parts of your code, ensuring they work as expected.
For tRPC, a "unit" often refers to a single procedure (query or mutation). We'll learn how to test these procedures independently, without needing a full server running.
Benefits of Procedure Testing
Unit testing tRPC procedures offers several key advantages:
- Reliability: Catch bugs early in development before they reach production.
- Speed: Tests run quickly, providing instant feedback.
- Isolation: Pinpoint issues to specific procedures, not complex integrations.
- Type Safety: Ensures your procedure's inputs and outputs match your TypeScript definitions.
