However this testing concerns me a lot, we all agreed that we would focus on automated testing both on the unittest level and on the functional level. This is the first merge request since we had the last discussion on testing (related to merging the javelin and other branches). The clear consensus was that commits would have to be accompanied by unittests (at least for the changed pieces of code) and preferable some automated functional test. Considering that, I think that a merge is not the right this to do at the moment. Instead of merging into master and then fixing stuff, we should focus on adding testing to this branch so we can merge a well-tested unit later. Notice my use of 'we' here, we all said focus on testing, so we all should help out. Unfortunately I'm pretty busy with packaging and the $dayjob, but if you have something I can help you with regarding setting up unittests feel free to let me know. You already mentioned that you have some, but the databases need to be mocked? It would be great if you could spend some time to details what tests you have in place, so we can fix those. With the help of the cobertura report we can figure out where the risks are. Prassana and myself are also working on the automated test framework, so if you have some marvin tests, we can help to automate them. Anybody else willing to help put in some tests into the storage_refactor branch? Cheers, Hugo
