Overview
Nock is a Dart and Flutter library for mocking HTTP requests, enabling isolated testing of applications without making actual network calls. It allows developers to define expected request patterns and responses, ensuring reliable and repeatable test environments. Ideal for unit and integration tests, nock helps verify how your app handles various HTTP scenarios, including success, errors, and edge cases. By intercepting HTTP requests during testing, it enhances test speed and reliability. The library supports all major platforms, including Android, iOS, macOS, Windows, and Linux.
