PactExpectations

Pact response convert to stub.

Installation

Add this line to your application's Gemfile:

gem 'pact_expectations'

And then execute:

$ bundle

Or install it yourself as:

$ gem install pact_expectations

Usage

for example

class APIClient
  def item(id)
    # Sending api request
  end
end

PactExpectations.add_response_body_for(
  "a request for an item",
  Pact.like(
    id: 1,
    name: "pen",
  ),
)

## CDC testing with Pact
describe APIClient, pact: true do
  describe "#item" do
      before do
        api
          .given("an item exists")
          .upon_receiving("a request for an item")
          .with(method: :get, path: "/item/1")
          .will_respond_with(
            status: 200,
            body: PactExpectations.response_body_for("a request for an item"),
          )
      end
      it { expect(APIClient.item(1).name).to eq "pen" }
    end
  end
end

## Stub Remote Facade's method
describe ItemsController do
  describe "show" do
    before do
      allow(APIClient).to(
        receive(:item).with(1).and_return(PactExpectations.reified_body_for("a request for an item"))
      )
    end
    it do
      get :show, id: 1
      expect(assigns[:item].name).to eq "pen"
    end
  end
end

Verify expectation was called.

RSpec.configure do |config|
  config.after(:suite) do
    PactExpectations.verify if ENV["PACT_VERIFY_EXPECTATIONS"] == "1"
  end
end

Development

After checking out the repo, run bundle install to install dependencies. Then, run rake spec to run the tests.

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.
