What are coverage metrics and how do they impact software quality?

Coverage metrics are measurements that indicate the extent to which your code is tested. They help identify untested parts of your codebase, which can lead to potential bugs.

Can you explain the different types of coverage metrics?

Sure! The main types include statement coverage, branch coverage, function coverage, and line coverage. Each type measures different aspects of code execution.

How can I improve my coverage metrics?

You can improve coverage metrics by writing more unit tests, integrating automated testing tools, and regularly reviewing your test cases to ensure they cover all critical paths.

Is there a specific coverage percentage I should aim for?

While there's no one-size-fits-all percentage, aiming for 80% coverage is a common goal. However, focus on covering critical areas of your application.
