# Test the niv binary
#
# A webserver is started to mock API requests to GitHub and to serve
# files. niv commands are then executed and the some elements of the
# resulting sources.json are verified with jq.
#
# Note that niv needs to be patched to use http://localhost:3333
# instead of https://github.com since it doesn't support another
# GitHub url (while the GitHub API permits that).
#
# To mock GitHub, JSON responses of the real GitHub API have been
# copied to files (in the data folder) and are used by the webserver
# to serve GitHub API responses.
