Github action that keeps track and retrieves previous workflow runs status for the same workflow on the same branch. According to current and previous runs status, it will send a notification to a Slack channel using an Incoming webhook app.

At the end of a workflow, on success() and on failure(), call this action with the current status as a parameter (success/failure). This action will first check the previous workflow status and will send a Slack notification according to the current workflow status. Status is retrieved from cache if the current workflow has already run previously (from re-run all jobs button for example). If it's the first time this workflow runs, this action will retrieve previous workflow status on the same branch with gh cli using provided github-token.

It'll compare last/current workflow status and will send a notification to Slack if:

• Current status is failure and it's the first time this workflow runs for the current branch.
• Current status is failure and previous run status was success.
• Current status is success and previous run status was failure.

It'll not send a notification to Slack if:

• Current status is success and previous run status was success.
• Current status is success and it's the first run.
• Current status is failure and previous run status was failure.

You need to define this secret: YOUR_SLACK_WEBHOOK: Webhook URL from Slack Incoming Webhook application

- uses: reside-eng/workflow-status-notification-action@v1
  with:
    # Status of the current run
    #
    # Default: failure
    # Required: true
    current-status: ''

    # Webhook URL with token for notifications
    #
    # Required: true
    slack-webhook: ''

    # Status of the current run
    #
    # Required: true
    github-token: ''
