Simulating Webhooks

As you are developing your app, you will likely want to test it by repeatedly trigging the same webhook. You can simulate a webhook being delivered by saving the payload to a file, and then calling probot simulate from the command line.

To save a copy of the payload, go to the settings page for your App, and go to the Advanced tab. Click on one of the Recent Deliveries to expand it and see the details of the webhook event. Copy the JSON from the the Payload and save it to a new file. (test/fixtures/issues.labeled.json in this example).

Next, simulate this event being delivered by running:

$ node_modules/.bin/probot simulate issues test/fixtures/issues.labeled.json ./index.js
