# 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.
