# TEST POST/PUT/DELETE REQUESTS

# This requires a path to a token stored in an environment variable. To do this,
# authorize the app and let httr store it locally. Then add this to ~/.profile:
#
#   export TOKEN_PATH=~/path/to/.httr-oauth
#
# The value will become available on the next login, use `Sys.getenv` to check.

# Avoid running when auth is not available.

# In the below, some of the tests rely on the results from the other tests,
# which could be considered bad practice. A setup-teardown approach would be most
# appropriate, with resources created beforehand. This would allow for tests
# like "attach file to a card" to be performed independently from card creation
# tests. On the other hand, it is better to have suboptimal tests rather than
# no tests at all.
