Test coverage and code coverage are two key metrics that evaluate testing from different angles. Although related, they serve distinct purposes. - Test coverage focuses on validating features and user scenarios. - Code coverage measures how much of the code is executed during tests. - Using both together gives a more complete view of testing effectiveness. ## Test Coverage Test coverage measures how thoroughly your application’s features and user scenarios are tested. It ensures the system behaves as expected from a user perspective. - Validates business requirements and features - Ensures compatibility across browsers and devices - Covers complete user workflows (end-to-end) ## Code Coverage [Code coverage](https://www.geeksforgeeks.org/software-engineering/code-coverage-testing-in-software-testing/) measures the percentage of the codebase that is executed during the testing process. It focuses on validating the code itself rather than the application’s features. Code coverage is typically performed by developers during unit testing to verify that all parts of the code are executed and that no code paths are left untested. - ****Statement Coverage:**** Checks whether each line of code is executed at least once. - ****Branch Coverage:**** Verifies that all decision paths (e.g., if/else conditions) are tested. - ****Path Coverage:**** Ensures different execution paths through the code are covered. ## Test Coverage vs Code Coverage Feature Test Coverage Code Coverage Definition Measures how much of the application functionality is tested Measures how much of the source code is executed during testing Focus Area Requirements, features, use cases Code statements, branches, paths Perspective Business / Functional perspective Technical / Developer perspective Goal Ensure all requirements are tested Ensure maximum code execution during tests Measured By Test cases vs requirements Lines, statements, branches, methods executed Example Testing login, signup, payment features Checking if all if, for, methods are executed Level High-level (functional coverage) Low-level (code-level coverage) Tools Test management tools (e.g., TestRail) Coverage tools (e.g., JaCoCo, Cobertura) Dependency Depends on requirement completeness Depends on test execution Limitation May miss untested code paths High coverage doesn’t guarantee correct logic Comment ### Explore Software Engineering Basics -
