Test coverage enables testers to identify gaps at early stages, get better coverage and to remove redundant cases. It basically saves ๐๐๐๐ and ๐๐๐๐๐ข.

โ ๏ธ Some methods are related, for example:
- Path coverage implies both instruction coverage and test point coverage;
- Instruction coverage does not imply test point coverage.
But test coverage is challengingโฆ
1๏ธโฃ With test coverage, it is hard to access accurate test results. Testers are having a hard time to understand why a test is returned ๐๐ค ๐๐ or to increase coverage through ๐ก๐ ๐ค๐๐ฅ๐๐ง๐ ๐๐๐ ๐๐๐๐๐ฅ๐๐ง๐ ๐ฅ๐๐ค๐ฅ ๐๐๐ฅ๐.
