High-Impact, Minimal-Effort Cross-Browser Testing
Cross-browser testing is time-consuming and laborious. This, in turn, makes it expensive and prone to human error… so, naturally, we want to do as little of it as possible. This is not a statement we should be ashamed of. Developers are lazy by nature: adhering to the DRY principle, writing scripts to automate things we’d otherwise have to do by hand, making use of third-party libraries — being lazy is what makes us good developers.
The traditional approach to cross-browser testing doesn’t align well with these ideals. Either you make a half-hearted attempt at manual testing or you expend a lot of effort on doing it “properly”: testing in all of the major browsers used by your audience, gradually moving to older or more obscure browsers in order to say you’ve tested them.
