What is JUnit test coverage and why is it important?
JUnit test coverage refers to the measurement of how much of your code is tested by JUnit tests. It's important because it helps ensure that your code is reliable and reduces the chances of bugs.
How can I measure test coverage in my JUnit tests?
You can measure test coverage using tools like JaCoCo or Cobertura, which integrate with your build process to provide coverage reports.
What is considered good test coverage?
A good test coverage percentage is often considered to be around 70-80%, but the ideal coverage can vary depending on the project and its requirements.
Can high test coverage guarantee bug-free code?
No, high test coverage does not guarantee bug-free code. It indicates that many paths are tested, but it doesn't ensure that all edge cases are covered.
