# test_60_rankings_alliances_data.R
# Version 2.0.0
#
# By default, these tests run locally, without making HTTP connections to the
# FIRST API server. To run test that firstapiR connects to the FIRST API
# server, create character vectors named "username" and "key" in the console
# and set their values to the username and key assigned to you by FIRST. Then
# run the tests from the console using testthat::test_dir() or
# testthat::test_file().
