> Code coverage percentage numbers on a dashboard are a risky business. They can give you a false sense of confidence. Because you can have 100% code coverage and be plagued by multitude of bugs if you do not test what the code is supposed to do. Or, conversly, I've been in charge by really awkwardly testable code.. which ends up being really reliable. Plugin loading, config loading (this was before you spring boot'ed everything in java). We had almost no tests in that context, because testing the edge cases there would've been a real mess. But at the same time, if we messed up, no dev environment and no test environment would work anymore at all, and we would know. Very quickly. From a lot of sides, with a lot of anger in there. So we were fine. |
