The following page has been changed by StephenKestle: http://wiki.apache.org/jakarta-commons/Collections/GenericCollections/DevelopmentGuidelines The comment on the change is: Added test coverage section ------------------------------------------------------------------------------ (This page needs debate or consensus) - == Testing == + == Testing / QA == As a core Java development API (and without any external system dependencies), Collections should have a set of tests that are '''deterministic (quasi-mathmatical) proofs''' of the operation of the system. Each test should stand alone. === JUnit 4 === @@ -13, +13 @@ === Mock Objects === For testing the new version, we will be using [dynamic] Mock Objects. This is because they provide absolute isolation of the classes under test. Because the collections package is a core api, and is relatively simple, there is no need to test with fully constructed objects [and they'd get in the way over time]. + === Coverage === + (This really needs soem debate) + For many of the classes, 100% coverage is warranted - CollectionUtils etc. In others, some leniency may be warranted (PredicateUtils.andPredicate). However, 100% should be aimed for as this is a core java api, and where it is not achieved, some explanation/consideration should be given. + + [http://emma.sourceforge.net EMMA] seems to be a good fit for acheiving high coverage, as it supports the notion of [http://emma.sourceforge.net/faq.html#q.fractional partial line coverage]. It's license is CPM (which I think is ASL compatible), where as Cobertura is GPL'd, and so is not suitable [or is it? this is only for building, and is not extended]. + --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
