Overview
The mock_exceptions package enables developers to simulate exception behavior in mock objects during testing. It allows specific method calls on a fake or mock to throw exceptions, which is particularly useful for testing error-handling scenarios without relying on real implementations. This helps ensure robustness in test cases by validating how code responds to failures. The package integrates seamlessly with Flutter's testing ecosystem and supports all major platforms. It is ideal for unit and integration tests where controlled failure conditions are needed.
Use cases
