# e2e testing helper script
# Preconditions:
# 	- Ran in the top directory of the `beat.web` repository
#	- `Buildout` has already been ran successfully
#	- Default development environment configurations
#	- $SHELL is BASH or ZSH
# Postconditions:
#	- `nohup.out` file will exist in top directory
#	- If there was not a `django.sql3` db file, there will be one
#
# SUGGESTION: The vast majority of the time is spent generating a fresh db via
# `./bin/django install`. You may have a file named `template.django.sql3`
# in the top dir that will be copied and used as the initial db to massively
# speed up testing.
