Episode Synopsis

What is Code Coverage?Code coverage is a metric that measures how much of your source code is executed during testing. It helps identify untested areas and improves overall test effectiveness. 🧑‍💻🔍Why Use Code Coverage?✔️ Measures test efficiency 📊✔️ Identifies untested code ❌✔️ Provides a quantitative analysis 📈Types of Code Coverage:📝 Statement Coverage – Ensures every line of code is executed at least once.🔀 Branch Coverage – Tests all possible branches in decision-making constructs.🤔 Decision Coverage – Validates all true/false conditions in the code.🔢 Condition Coverage – Evaluates logical sub-expressions independently.⚙️ Finite State Machine (FSM) Coverage – Tests transitions between system states.Code Coverage vs. Functional Coverage🛠️ Code Coverage – Focuses on testing the structure of the code.🎯 Functional Coverage – Ensures all features work as expected.Popular Code Coverage Tools:🔹 Cobertura🔹 Clover🔹 Emma🔹 Sonar🔹 Bullseye for C++Using code coverage helps improve software quality, but it doesn’t guarantee the software is bug-free! 🚀💡
