Test Coverage

Term from Quality Assurance industry explained for recruiters

Test Coverage is a way to measure how thoroughly software has been tested. Think of it like checking a house for problems - you want to make sure you've looked in every room and corner. When someone mentions "test coverage" in their resume, they're talking about what percentage of the software's code has been verified through testing. It's like having a checklist showing which parts of a program have been tested and which haven't. Higher test coverage usually means better quality assurance, though 100% coverage isn't always necessary or practical. This term is often paired with related concepts like "code coverage," "functional coverage," or "requirements coverage."
