fake-mechanize¶ ↑

FakeMechanize provides methods and classes to write offline tests for applications which relies on Mechanize. It replace Mechanize and emulate an agent which aim to act like a real Mechanize Agent. Fake agent accepts options to define queries and their answers.

• Simple examples to test a basic api

  # Initialize a fake agent
  @http_agent = FakeMechanize::Agent.new
  
  # Create answers and their params
  @http_agent.respond_to do |mock|
  
    # Answers to get queries to http://api.example.com/users/count?group=students
    # with the string "42"
    mock.get :uri => "http://api.example.com/users/count",
             :parameters => {:group => "students"},
             :body => "42"
  
    # Answers to post queries to http://api.example.com/users/3/activate
    # with the string "true"
    mock.post :uri => "http://api.example.com/users/3/activate",
              :body => "true"
  
    # Answers to post queries to http://api.example.com/users/authentify
    # with the string "Qt5c1HWwCXDhKskMrBqMdQ".
    # This example could be an authentication process
    mock.post   :uri => "http://api.example.com/users/authentify",
                :parameters   => {:Email => 'jack@bauer.com', :Passwd => 'secure'},
                :body => "Qt5c1HWwCXDhKskMrBqMdQ"
  
    # Will reply with an http error code of 403 with no body if the post query
    # to http://api.example.com/users/authentify does not have specified parameters.
    mock.error  :uri => "http://api.example.com/users/authentify",
               :params_not_equal  => {:Email => 'jack@bauer.com', :Passwd => 'secure'},
               :method => :post,
               :status => 403
  end
  
  # Now you can use this agent like a real one
  r = mock.get("http://api.example.com/users/count", :group => "students")
  # => WWW::Mechanize::File
  r.body # => "42"
  
  # Posting
  r = mock.post("http://api.example.com/users/authentify",
                :Email => "jack@bauer.com", :Passwd => "secure")
  r.status # => 200
  r.body   # => "Qt5c1HWwCXDhKskMrBqMdQ"
  
  # Handling errors
  r = mock.post("http://api.example.com/users/authentify",
                :Email => "jack@bauer.com", :Passwd => "bad")
  r.status # => 403
  r.body   # => nil
