We are small startup/company. We don't want to ship broken versions to our customers. For now we don't have enough budget to spend on creating a QA & Testing team. How does new startups & small companies doing testing before shipping apps? I'm trying to test 2-3 times after building every feature. But that's not enough sometimes for detecting business critical bugs.
Simply I'm looking for an advice: how should we invest on testing? Or should we?
