CoverageFailDemo
ExCoveralls doesn't seem to be considering each line in a case statement as relevant, which means coverage reports aren't always accurate. This project demonstrates this behaviour.
After downloading the repo, run mix deps.get and then mix coveralls. You'll see that the tool reports a 100% coverage rate. However, the test only covers one branch of the case statement.
- Expected behaviour: 66.6% coverage (with 3 relevant lines, 2 hits)
- Actual behaviour: 100% coverage (with 1 relevant line, 1 hit)
