Execution order of Jest/Jasmine test code

Execution order of Jest/Jasmine test code

While tests run in source order, surrounding code does not which can lead to hard to debug issues.

Compare the test file below with the sample output below that and note the order of the log messages.

Key points

  • Any code not inside of it, beforeAll, afterAll, beforeEach or afterEach runs immediately on initialisation.
  • This means code at the end of your file runs before even your before hooks.

cloud-init "nocloud" networking setup

cloud-init is absolute cancer. Its code is horrible. It has no documentation at all.

It took me 5 fucking hours to figure out how to properly configure networking on recent cloud-init (Ubuntu 16.04 cloud image) with local datasource.

It's not mentioned anywhere you need to provide dsmode: local. (but only if you need network-config, besides that everything is fine; someone below noted that -m flag does the same thing, good to know) Of course nobody needs documentation for network-config format either. (cloudinit/net/__init__.py is a protip, enjoy the feces dive)

Oh, and by the way - no, it's not possible to provide network-config to uvt-kvm without patching shit.

guix notes

overview

  • guix is pronounced geeks
  • guix wants linux-libre kernel for containerization
  • changing any input to a guix package definition results in a different hash on disk (different directory)
