How to Fail with 100% Test Coverage
With an expressive language such as Ruby and with modern test practices, 100% C0 test coverage is readily achievable. But 100% coverage is meaningless without other supporting habits and practices. Over the last few years, we have taken dozens of projects to 100% coverage, and there are still plenty of things that can go wrong.
We will look at examples of each of these problems (and others as well), and show how to prevent them from infecting your project.
- Fragile Mocking
- Incidental Coverage
- The Ugly Mirror
- Overspecification
- Slow Tests
- Underspecification
- Shallow Tests
- Invisible Code
