I'm primarily active on Code Review, where we review people's code. Someone posted a question there that was about improving the testability of their code.
You'll need 10k rep to see it, so here's a link and an image:
I understand that if you look at this question, it's more a code review request than would be appropriate here, but if you alter the wording to suit the main question (how do I effectively test DAO classes in Spring) then it seems like it could fit here?
Since the asker has deleted their question, this is less about this specific question and more about "do you take such implementation-specific questions". I'd like to know for next time that such a thing happens, so that I can point users here, rather than just state "sorry, your question is off-topic at Code Review, kthxbye".
I had a look at your tour too; it's not very specific as it just states that "Specific issues with software quality assurance or testing" are on topic and "Anything not directly related to software quality assurance or testing" is off topic, and this seems more than just tangentially related.
Additional request: you guys need a site-scope tag. Would you mind making it?
