End-to-End Testing Strategies
Implement end-to-end tests to simulate user flows and ensure the entire tRPC application functions as expected.
Test Your App Like a Real User
Welcome to End-to-End (E2E) Testing! This strategy simulates a real user interacting with your application from start to finish. It covers the entire stack: your frontend, backend, database, and network.
E2E tests ensure that all components work together seamlessly, just as they would in a live environment. Think of it as a robot user clicking, typing, and verifying your app's behavior.
Beyond Type Safety: Full Stack Validation
While tRPC provides excellent end-to-end type safety, E2E tests serve a different, crucial purpose. Type safety helps prevent bugs at compile time, but E2E tests catch issues that might arise at runtime.
These include deployment problems, configuration errors, network issues, and integration bugs that static analysis simply can't detect. E2E testing validates the actual user experience across your entire tRPC-powered application.
