*wtaf is happening?*
I googled for the cause of a "double callback" error and found out that supertest was throwing it when I was attaching a file to the API request. found no conclusive way to solve it, just that "supertest does it from time to time".

Trying to investigate further, I made a function to repeat the API request 5 times in a row. Everything passed. The run it again. Two failed. Again and everything passed.

this is bullshit

fml

Mocha or Tape (both with supertest)? For Backend testing. Api, graphql, that shit.

What would you prefer and why?
