Automock

Generate WebAPI mocking response data from your rails application's request-spec.

And run proxy server for mocking response.

Inspired by autodoc.

Add this line to your rails application's Gemfile:

gem "automock", group: :test

Download and install by running:

$ bundle install

And setup mocking server.

$ rake automock:setup

This generate automock directory under your rails root.
Mocking server is inside it. I recommend adding automock directory to .gitignore.

Then run mocking server.

$ rake automock:server

By default, proxy server use 8001 port and target application using 3000 port.
Mocking management server use 8000 port.
Now you can access it, localhost:8000.
And access localhost:8001, you can receive response by proxy.

Run rspec with AUTOMOCK=1 to generate mocking data for your request-specs tagged with :automock.

AUTOMOCK=1 rspec

describe 'GET /api/v1/users' do
  context 'This is test API', automock: true do
    before do
      get '/api/v1/users'
    end
    it 'receives 200 and users json' do
      expect(response.status).to eq 200
    end
    # and more example...
  end
end

You can manage mocking data, on or off, by mocking response management server. By default, mocking management server use 8000 port. So you can access it.

Selected mocking data is used by proxy.
Unselected api is passed through normally.

You can change automock's using port by rake args.

• automock_port
• rails_port
• proxy_port

Example:

$ rake automock:server automock_port=3001 rails_port=3002 proxy_port=3003

After checking out the repo, run bin/setup to install dependencies. If you run mocking server, run bin/server to start it.

Then, run rake spec to run the tests for ruby code.
And change directory to server, then run npm run test to run the tests for mocking server.
