Your list is great :-) I'm possibly old and cynical these days but I'd maybe add '...and nothing seems to be getting much better'.
On the testing side - I've recently started running 'mutation tests' on my code (infection.github.io/ in particular). It's been quite eye-opening and a little depressing watching it flip 'true' to 'false' all over the place and tests still passing :-/. In my (feeble) defence, a lot of the time it's because in one test I'll be checking that related-fieldX has changed the way I expect and in another checking the true/false aspect - but it's still pretty eye-opening and has caught a lot of things I'd otherwise have missed :-)
