# This script is designed for developers who want to test their code
# against Complement.
#
# It makes a Synapse image which represents the current checkout,
# builds a synapse-complement image on top, then runs tests with it.
#
# By default the script will fetch the latest Complement master branch and
# run tests with that. This can be overridden to use a custom Complement
# checkout by setting the COMPLEMENT_DIR environment variable to the
# filepath of a local Complement checkout.
#
# A regular expression of test method names can be supplied as the first
# argument to the script. Complement will then only run those tests. If
# no regex is supplied, all tests are run. For example;
#
# ./complement.sh "TestOutboundFederation(Profile|Send)"
#

# Exit if a line returns a non-zero exit code
set -e

# Change to the repository root
cd "$(dirname $0)/.."

# Check for a user-specified Complement checkout
