# Docker file for creating a docker container that can run the tests.
#
# Create the image:
# docker build -t chasquid-test -f test/Dockerfile .
#
# Run the tests:
# docker run --rm chasquid-test make test
#
# Get a shell inside the image (for debugging):
# docker run -it --entrypoint=/bin/bash chasquid-test
