Describe the purpose of code coverage reports in testing, and how can they be used to improve the quality and completeness of a test suite?

Code coverage reports provide insights into how much of the source code is exercised by a test suite. They measure the extent to which the code has been tested and identify areas that are not covered by any tests. This helps in improving the quality and completeness of the test suite. The purpose is to quantify how well the tests are testing the code. Code coverage is typically expressed as a percentage. There are several different types of code coverage metrics: 1. Statement Coverage: Measures the percentage of statements in the code that have been executed by the tests. 2. Branch Coverage: Measures the percentage of branches (e.g., `if` statements, `switch` statements) that have been executed by the tests. This ensures that both the `true` and `false` branches of each condition....
