# This file should be sourced by all test-scripts
#
# Main functions:
#   prepare_tests(description) - setup for testing, i.e. create repos+config
#   run_test(description, script) - run one test, i.e. eval script
#
# Helper functions
#   cgit_query(querystring) - call cgit with the specified querystring
#   cgit_url(url) - call cgit with the specified virtual url
#
# Example script:
#
# . setup.sh
# prepare_tests "html validation"
# run_test 'repo index' 'cgit_url "/" | tidy -e'
# run_test 'repo summary' 'cgit_url "/foo" | tidy -e'
