I'm getting really tired of those dumbass programmers that do not understand shit and then come to me when production breaks. (I am also a programmer, not really a DevOps engineer, but I'm the least worst at DevOps stuff, so it's my job...).
We're programming some kind of document management tool. Today we had a release, and one of the new features is to download all of your documents as a zip file, which is asynchronuously generated. When it's done, the user gets a mail with the download link to the zip file.
The feature works basically, but today it broke our production service, as somebody was running a test of it.
Turns out all the documents are loaded into memory to be zipped. So if you have 2 gigs of documents, a container with memory restrictions in that area will crash.
I asked the programmer who reported this «ops problem» to me, why he didn't just shit the files into a temp foler in order to zip them in there.
He told me that he wanted to do so, but did not know how to mock this for a unit test, and therefore went to the in-memory «solution», which was easier for him to mock.
For fuck's sake, unit tests and mocks are fucking tools, not ends in itself! I don't give a fuck about your pointless mocking code when the application crashes!
When I got to deal with such dumbasses, I'd prefer to mock those motherfuckers with a leaky bucket of liquid shit, which basically accomplishes the same task from my perspective: dripping shit all over the place and make everything suck as fuck.3
