How devs make sure there is no regressions when they submit any changes
Hi. I wonder how the "team" in development's charge face this problem? from github I see a lot of regressions. Even now just switching between two beta I came across regressions.. I know that are betas.. but I don't expect regression bugs rather new bugs.
They have a QC system in place? Idk.. some unit tests? integration tests? Or are so fast placed that they can't use any of them?
Someone know an answer?
