What is Statement Coverage?

Statement coverage is a metric used in software testing to measure the extent to which the statements in a program have been executed during testing. It is a measure of the percentage of statements that have been covered or executed by the test cases.

Statement coverage aims to ensure that every statement in the code has been executed at least once during testing. It helps in identifying areas of the code that have not been tested and may contain potential defects. By achieving high statement coverage, it increases the confidence in the quality and reliability of the software.

To calculate statement coverage, the total number of statements executed during testing is divided by the total number of statements in the code and multiplied by 100 to get the coverage percentage. The goal is typically to achieve 100% statement coverage, although it may not always be feasible or necessary depending on the complexity of the code.

Statement coverage is a fundamental measure of test coverage and is often used in conjunction with other coverage metrics such as branch coverage and path coverage to ensure thorough testing of the software. It helps in identifying areas of the code that have not been tested and may contain potential defects, allowing for targeted testing and debugging efforts.
