# Given a deno executable, this script executes several integration tests with
# it. The tests are stored in /tests/ and each is specified in a .yaml file
# where a description, command line, and output are specified. Optionally an
# exit code can be specified.

# Usage: integration_tests.py [path to deno executable]
