Code Coverage in Software Testing: What It Reveals About Test Quality?
Napsal: pon pro 15, 2025 7:19 am
Code coverage in software testing measures how much of an application’s source code is executed when tests run, offering clear visibility into the effectiveness of a test suite. By tracking elements such as statements, branches, conditions, and paths, code coverage helps teams identify untested logic, dead code, and high-risk areas that may behave incorrectly in production. Rather than focusing on how many tests exist, it highlights whether tests are meaningfully exercising the system’s core functionality.
When used correctly, code coverage in software testing supports better decision-making across the development lifecycle. It guides teams toward smarter test design, improves confidence during refactoring, and acts as an early warning signal for gaps in quality. While high coverage alone does not guarantee defect-free software, combining coverage insights with well-designed test cases and risk-based testing significantly strengthens overall software reliability.
