Are Your Tests Well-Traveled? Thoughts on Test Coverage

There are many places to visit it the world and it can be interesting to see “where you’ve been”. There are many places in software for tests to visit, and seeing “where the tests have been” can be very interesting for testers. Dot Graham explains what coverage is, and why it can be misleading to talk about 100% coverage. Coverage is a relationship between the tests and the software being tested, and is an objective measurement of some aspect of thoroughness of the testing. Dot will discuss the ways in which the term coverage is mis-used, and the four caveats of coverage which every tester should be aware of. She will speak to two important questions about coverage; coverage of what and why do we need coverage and will provide her perspective on the thoroughness of testing.
