Running the test suite requires at least two twitch accounts, one moderator account and one normal account. The channel used must be the same - This is so timeout/ban methods can be tested with the mod account. Using these two accounts, set the following environment variables:
TWITCHBOT_USERNAME=mod_username
TWITCHBOT_OAUTH=oauth:mod-oauth-token
TWITCHBOT_CHANNEL=mod_channel
TWITCHBOT_USERNAME_NON_MOD=non_mod_username
TWITCHBOT_OAUTH_NON_MOD=oauth:non-mod-oauth-token
TWITCHBOT_CHANNEL_NON_MOD=mod_channelTo run the tests (powered with Mocha), use the following command:
yarn test
