I’m not defending this or anything, but you said that this should have been manually tested, and I’m just observing that manually testing a system as complex as Twitter, in any kind of comprehensive way, is not at all trivial.
- mostlysimilar 3y agoI get you and that makes sense, and we're discussing things at a scale that I don't have experience with. I just wouldn't have been comfortable shipping this code without observing it functioning in some way. If your production environment is so complex that you can't properly test things locally then you should certainly have a staging environment that makes that kind of testing possible. I would never be satisfied doing zero manual testing of the code I ship.
