Savon::Spec

Savon testing library

Installation

Savon::Spec is available through Rubygems and can be installed via:

$ gem install savon_spec

Dependencies

Currently, the dependencies are very strict. Savon::Spec is meant to be used with:

Note to self: the required versions for RSpec and Mocha could probably be lower.

Getting started

Macros

Include the Savon::Spec::Macros module:

RSpec.configure do |config|
  config.include Savon::Spec::Macros
end

Mock

By including the macros, you have access to the savon method in your specs. It returns a Savon::Spec::Mock instance to set up your expectations. It's based on Mocha and comes with similiar methods:

#expects(soap_action)       # mocks SOAP request to a given SOAP action
#stubs(soap_action)         # stubs SOAP requests to a given SOAP action
#with(soap_body)            # expects Savon to send a given SOAP body
#raises_soap_fault          # raises or acts like there was a SOAP fault
#returns(response)          # returns the given response

Fixtures

Savon::Spec works best with SOAP response fixtures (simple XML files) and a conventional folder structure:

~ spec
  ~ fixtures
    ~ get_user
      - single_user.xml
      - multiple_users.xml
  + models
  + controllers
  + helpers
  + views

When used inside a Rails 3 application, Savon::Spec uses the command Rails.root.join("spec", "fixtures") to locate your fixture directory. In any other case, you have to manually set the fixture path via:

Savon::Spec::Fixture.path = File.expand_path("../fixtures", __FILE__)

The directories inside the fixture directory should map to SOAP actions and the XML fixtures inside those directories should describe the SOAP response. Please take a look at the following examples to better understand this convention.

An example

user.rb

class User

  def self.all
    response = client.request :get_all_users
    response.to_hash.map { |user_hash| new user_hash }
  end

  def self.find(user_id)
    response = client.request :get_user do
      soap.body = { :id => user_id }
    end

    new response.to_hash
  end

end

user_spec.rb

describe User do

  describe ".all" do
    before do
      savon.expects(:get_all_users).returns(:multiple_users)
    end

    it "should return an Array of Users" do
      User.all.each { |user| user.should be_a(User) }
    end

    it "should return exactly 7 Users" do
      User.all.should have(7).items
    end
  end

  describe ".find" do
    before do
      savon.expects(:get_user).with(:id => 1).returns(:single_user)
    end

    it "should return a User for a given :id" do
      User.find(1).should be_a(User)
    end
  end

end
