25.13. Code Coverage

Try these first

1. 1.

   What is code coverage?

   Hint

   Think about what percentage means in testing context.

2. 2.

   List one tool used for measuring code coverage.

   Hint

   Recall any tools mentioned in the lesson.

3. 3.

   What is the primary purpose of code coverage?

   • To measure code execution
   • To increase code size
   • To monitor code performance

   Hint

   Think about the relationship between testing and code execution.

4. 4.

   True or False: High code coverage guarantees that the code is bug-free.

   • True
   • False

   Hint

   Recall our discussions on quality versus coverage.

5. 5.

   Consider a situation where the code is 70% covered but crucial error handling is untested. What implications does this have for software quality?

   Hint

   Analyze how coverage might misrepresent safety if critical paths are neglected.

6. 6.

   You are tasked to improve the code coverage of an API which currently sits at 60%. Outline a strategy for identifying untested code.

   Hint

   Think about both automated tools and manual review processes to identify weaknesses.
