This bash script allows for automated TDD development of a Strata project. It is hard coded for Mac and requires Behat for BDD.

tdd

#!/usr/bin/env bash
#
# This bash script is hard-coded for bash and MacOS. It allows for TDD
# development with PHPUnit and Behat from the command line, assuming
# all the dependencies are present.
#
# It is intended to fit in a self calling script for portability even
# if it makes the script look unwieldy.
#
# Invoke the script using:
#
# $ bin/tdd watch


# Env variables
# -------------
