Out of interest, what language ecosystems do you tend to work in?
replyMy guess is that some languages - like Go - have a more robust testing culture than other languages like PHP.
Not who you asked but I think it comes down to risk/reward. The consequences of some user finding a big in most websites is low, compared to the risk of an astronaut finding a bug the hard way whilst attempting re-entry.
replyThere is genuinely a reasonable and rational argument to “testing requires more effort than fixing the issues as users find them” if the consequences are low. See video games being notorious for this.
So, industry is more important than language I’d say.
I don't see testing as a quality thing any more, I see it as a developer productivity thing.
replyIf my project has tests I can work so much faster on it, because I can confidently add tests and refactor and know that I didn't break existing functionality.
You gotta pay that initial cost to to get the framework in place though. That takes early discipline.
