/*
This test is disabled by default because requires manual steps.

You need to set 3 system properties to run this test:
 -Dit.test.slack.enable=true to enable the test
 -Dit.test.slack.channel=#channel to inform the channel to send the message to
 -Dit.test.slack.token=<token> The token is a string that starts with xoxb

Preparing for the test. You need create a bot and give it the following scopes:
channel:history, channels:read and incoming-webhook. The settings for these,
along with the token can be found on the page OAuth & Permissions.
