A Test Harness is a collection of stubs, drivers and tools required to execute a test suite effectively. It provides the necessary infrastructure to run automated tests in a controlled environment.
Key Features:
- Components to simulate interactions with external systems.
- Tools to manage data input and output during testing.
- Frameworks to execute tests consistently across different scenarios.
A well-designed test harness streamlines the testing process, making it easier to validate software functionality under various conditions.
