This sample demonstrates how to post to a Slack channel in response to the completion of a test matrix in Firebase Test Lab. The message will look like this:

1. Add an Incoming Webhook to your Slack channel and take note of the Webhook URL.

2. Clone or download this repo and open this directory in a terminal:

   cd testlab-to-slack

3. You must have the latest Firebase CLI installed. If you don't have it, install it with npm install -g firebase-tools and then sign in with firebase login.

4. Configure the CLI locally by using firebase use --add and select your project in the list.

5. Install Cloud Functions dependencies locally by running: cd functions; npm install; cd -

6. Set the following environment variables so that the function can authenticate with Slack and post to the correct room:

   firebase functions:config:set slack.webhook_url="YOUR_SLACK_WEBHOOK_URL"

This sample comes with a web-based UI for testing the function. To test it out:

1. Deploy your function using firebase deploy --only functions
2. Navigate to the Test Lab section of the Firebase Console and start a test.
3. Once the test finishes running, check your Slack channel and view the new post!
