When I started here in June, we had no tests. Today, due to construction at the office, I was allowed to work from home. Because there were some troubles getting me access to development Web sites, I could only work via SSH and I took the time to work on our code coverage. We have gone from 0% in June to this:
file stmt branch cond sub pod time total ... Total 50.4 15.2 8.2 74.0 56.7 100.0 43.1
After spending some time with them, I successfully managed to reduce our coverage by almost a full four per cent!
file stmt branch cond sub pod time total ... Total 45.0 11.4 6.1 71.9 56.7 100.0 37.6
That was because we still have some untested code and I ensured that we at least had load tests for them. It lowers our coverage, but we at least know if we've introduced compilation errors.
