Why is test coverage important in software development?

Test coverage is crucial as it helps ensure that your code is thoroughly tested, reducing bugs and improving quality.

How do you measure test coverage?

Test coverage is typically measured using metrics like line coverage, branch coverage, and function coverage, which indicate how much of the code is tested.

What are the benefits of having high test coverage?

High test coverage leads to fewer bugs, easier maintenance, and greater confidence in code changes, ultimately improving software reliability.

Can you have too much test coverage?

Yes, excessive test coverage can lead to diminishing returns, where the cost of writing and maintaining tests outweighs the benefits.

What tools can help with measuring test coverage?
