- Import the functions used from ‘R6’, ‘httr’ and ‘jsonlite’ through
the namespace instead of attaching the packages with
library(), so the declared imports are used (removes the
check NOTE).
- The tests no longer contact a live server: they check the connection
object offline, and the one login test is skipped on CRAN and when
offline (removes the check ERROR seen on macOS).
- Add more information in error messages
