Testing

Testing is one of the best things in Hyper Fetch. With our architecture and focus on global singleton structure, tests can be largely based on the application’s configuration. This means tests are no longer sensitive to micro-changes (like changing endpoints or types). Everything reacts and adapts to tests or shows the appropriate error – making tests easier to maintain and faster to write.

If you're using the SDK pattern, testing becomes even simpler — create a mock SDK with $configure, inject it into your components, and every endpoint automatically returns controlled data with no network layer involved.

What you'll learn

1. The benefits of testing with Hyper Fetch.
2. How to isolate tests to ensure they are deterministic.
3. How to mock API requests for reliable and fast tests.
4. How to inject a test SDK with centralized mocks into your components.
