Overview

Coverage Improvement is a systematic workflow for identifying coverage gaps and writing missing tests. It's triggered when coverage is below a specified minimum percentage or when a user requests to improve coverage. The process involves analyzing current coverage, identifying gaps, writing missing tests, and verifying coverage. It prioritizes error handling paths, business logic branches, and edge cases when writing tests, and follows the AAA pattern (Arrange-Act-Assert) for test structure. The goal is to meet or exceed the coverage minimum with meaningful tests.
