What type of report is typically generated during functional testing to indicate test metrics?

A test coverage report is generated during functional testing to indicate test metrics because it provides insight into which parts of the application or system have been tested and to what extent. This report assesses the areas of functionality that have been covered during testing, along with the percentage of code or features exercised by the tests. It helps in identifying gaps in testing and ensures that critical functionalities are validated, thus giving stakeholders a clear view of the completeness and effectiveness of the testing process.

This type of report is essential for demonstrating the thoroughness of testing efforts and is particularly valuable in functional tests where specific functionalities need to meet defined specifications and requirements. It informs developers, testers, and management about risk areas that may need additional attention before the product release.

Other reports like the test results summary provide an overall view of whether tests passed or failed, but they do not reflect the completeness of test coverage. The test execution log details the steps taken during testing but is more focused on the actual execution rather than coverage metrics. An error report documents specific defects found during testing but does not give an indication of the overall test coverage.
