Test Runner

What is a Test Runner?

A test runner is a tool or software component that executes test cases for software applications. It automates the process of running tests and provides results on whether the tests passed or failed.

Purpose of a Test Runner

The main purpose of a test runner is to streamline the testing process by automatically running tests and reporting outcomes. This helps in ensuring that the software works correctly and meets its requirements.

How Does it Work?

1. Execute Tests: Runs predefined test cases or scripts.
2. Report Results: Provides feedback on whether the tests were successful or if issues were found.
3. Log Details: Records information about the tests and any errors encountered.

Benefits

1. Efficiency: Automates the execution of tests, saving time and effort.
2. Consistency: Ensures tests are run in the same way every time, reducing errors.
3. Immediate Feedback: Quickly identifies issues, allowing for faster fixes.
4. Integration: Often integrates with other tools and systems to support continuous testing.

Conclusion

A test runner simplifies the process of executing and managing tests, providing valuable feedback and helping to ensure the quality of software. By automating test execution and reporting results, it makes the testing process more efficient and reliable.
