2 comments

1. One of the steps into achieving the 100% coverage rule is to start with a better design. E.g. many times setter and getters are considered trivial to test and thereby causing people to skip testing them and thus lowering the coverage.
2. Agreed, the best way to improve coverage is to write less code.
