Software Testing And Quality Assurance Questions Medium
Test coverage and code coverage are two important concepts in software testing and quality assurance. While they are related, they have distinct differences.
Test coverage refers to the extent to which a software system has been tested. It measures the effectiveness of the testing process by determining which parts of the system have been exercised by the tests. Test coverage aims to ensure that all the requirements, functionalities, and use cases of the software are tested.
Code coverage, on the other hand, focuses specifically on the code itself. It measures the extent to which the source code of a software system has been executed during testing. Code coverage aims to identify which lines of code, branches, and paths have been covered by the tests.
In summary, the main difference between test coverage and code coverage is their scope. Test coverage is broader and encompasses the entire software system, including requirements and functionalities, while code coverage is narrower and focuses solely on the code. Test coverage ensures that all aspects of the software are tested, while code coverage ensures that all lines of code are executed.
Both test coverage and code coverage are important in software testing and quality assurance. Test coverage helps ensure that the software meets the specified requirements and functionalities, while code coverage helps identify areas of the code that have not been tested and may contain potential defects. By combining both test coverage and code coverage, software testers can achieve comprehensive testing and improve the overall quality of the software.
