Running Tests / Contributing

I have created a new slack team and a new web integration just for rspec purposes of testing this gem. Please use team: slackCI and the integration token D7eRlWzfbmZuqL2CqtXHS4ZA when writing more rspec tests, or use your own team + token just ensure that the correct team + token values are set back to defaults before creating a PR. This ensures that any contributers do not have to have a Slack account to contribute and test the gem.

Steps to contribute:

  1. Fork it ( )
  2. Create your feature branch (git checkout -b my-new-feature)
  3. Commit your changes (git commit -am 'Add some feature')
  4. Ensure all tests pass (rake test)
  5. Push to the branch (git push origin my-new-feature)
  6. Create a new Pull Request


Require the Gem:

require 'slack_ci'

Initialize a Slack object with your team name and Webhook Token:

slack ='team','token')

Post Messages to Slack by passing a Hash to SlackCi's say method:

message = {
  'text' => 'This is one awesome message',
  'channel' => '#general'
unless slack.say(message) == '200'
  abort("Message failed to post")

To Create a webhook token for your team, start here, and select any channel for the webhook. Then use the generated token from Slack as your access token. You will be able to post to different channels in slack with the same token, if you specify channel inside the message hash.

CLI Usage

Install the Gem:

gem install slack_ci

Follow the instructions above to create a webhook token for your team.

Create a config file inside of your home directory:

touch ~/.slackci.yml

And add the following contents into the YAML configuration file. The only required information in the file is your team name, and your token. Every other parameter is optional. NOTE: If you use icon_emoji and icon_url SlackCI will use the emoji configuration first, as there can only be one of either.

team: '<team_name>'
token: '<webhook-token>'
icon_url: '<icon_url>'
icon_emoji: '<icon_emoji>'
username: '<username>'

Once you have the configuration file written correctly, simply run the SlackCI binary from the terminal.

slackci #channel this is one interesting message

NOTE: Messages do not have to be quote delimited. Anything after the channel name will be added to the message. Including any "" and ":emoji:" that you wish to send to slack.
