Over confidence and coffee are the only unit tests I need

Running it in a test environment and then not having users test (vendor upgrade, in-house internal-facing app, or integration), and then being ordered to put it in prod, then people start mentioning the things they should’ve been mentioning all along. Can’t blame them, as our timelines are short and every department is overworked and varying degrees of being understaffed.

Let us be real honest, rarely your code isn’t completely broken.
