Half way through a 2 hour deployment, and a fucking test fails.
Yes, it takes 2+hours to run the tests.

Rerun in test environment: pass
Rerun in prod: pass
Rerun changed test in prod: fail..

Why, why you got to hate me for?
I love it when production is the place where config gets changed.

So, after having my mental breakdown with the 500k LoC Zend Frameshit PHFuck 5.5 with 0 test project, for a whole year; and after moving to a better job, I now inherited a React/Node/GraphQL project with a shitty architecture. It's so shit technical debt can almost be payed with actual cash... or flesh, ass-for-arch.

However, line test coverage is over 90%, so I guess it is an improvement.
