How do you get a 100 code coverage?

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.

What is acceptable code coverage?

Summary. Code coverage of 70-80% is a reasonable goal for system test of most projects with most coverage metrics. Use a higher goal for projects specifically organized for high testability or that have high failure costs. Minimum code coverage for unit testing can be 10-20% higher than for system testing.
