I like this joke from a while ago about testing "QA Engineer walks into a bar and he orders a beer. Orders 0 beers. Orders 99999999999 beers. Orders a lizard. Orders -1 beers. Orders a ueicbksjdhd. First real customer walks in and asks where the bathroom is. The bar bursts into flames, killing everyone."
Which leads into being very clear about what you want to achieve with testing, correctness, robustness, fit for purpose etc, and be clear how much effort you want to put into each area. Often I have seen people put a lot of effort into testing things that really doesn't have much payback compared to what they could be testing instead. So be careful of the opportunity costs of your testing efforts.
