WebhookRecorder

When you build a feature that makes calls to webhooks of subscribers, this library helps to test that behaviour.

This runs a simple WEBrick server, makes it accessible via ngrok and records the results. You can assert on the recorded requests to ensure the code you built made calls to registered webhooks.

Read the intro blog post here.

Dependency

This uses ngrok to publish URL that's accessible via internet. Ensure it'a available in PATH.

Installation

Add this line to your application's Gemfile:

gem 'webhook_recorder'

And then execute:

$ bundle

Or install it yourself as:

$ gem install webhook_recorder

Usage

• If you have ngrok account, set env. var NGROK_AUTH_TOKEN before running

it 'should respond as defined as response_config' do
  response_config = { '/hello' => { code: 200, body: 'Expected result' } }
  WebhookRecorder::Server.open(@port, response_config) do |server|
    #These URLs are accessible from internet
    p server.http_url
    p server.https_url

    # Register the webhook with any of the above URLs
    # Make call to the code that invokes webhooks
    # For e.g. if it made call to /hello with query params as q=1 and JSON body as {some: 1, other: 2}, you can assert like below.

    req1 = server.recorded_reqs.first
    expect(req1[:request_path]).to eq('/hello')
    expect(req1[:query_string]).to include('q=1')
    expect(JSON.parse(req1[:request_body]).symbolize_keys).to eq({some: 1, other: 2})
  end
end

• If you don't want to expose the stub server to internet and test only locally, you toggle the behavior with

  WebhookRecorder::Server.open(@port, response_config, false) do |server|
    # server.http_url and server.https_url will be nil
  end

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
