Overview

An integration Session instance represents a set of requests and responses performed sequentially by some virtual user. Becase you can instantiate multiple sessions and run them side-by-side, you can also mimic (to some limited extent) multiple simultaneous users interacting with your system.

Typically, you will instantiate a new session using IntegrationTest#open_session, rather than instantiating Integration::Session directly.

Instance Method Details

#delete(path, parameters = nil, headers = nil) ⇒ Object

Performs a DELETE request with the given parameters. See get() for more details.



166
167
168
 
# File 'lib/action_controller/integration.rb', line 166

def delete(path, parameters=nil, headers=nil)
  process :delete, path, parameters, headers
end

#follow_redirect! ⇒ Object

Follow a single redirect response. If the last response was not a redirect, an exception will be raised. Otherwise, the redirect is performed on the location header.

116
117
118
 
# File 'lib/action_controller/integration.rb', line 114

def follow_redirect!
  raise "not a redirect! #{@status} #{@status_message}" unless redirect?
  get(interpret_uri(headers['location'].first))
  status
end

#get(path, parameters = nil, headers = nil) ⇒ Object

Performs a GET request with the given parameters. The parameters may be nil, a Hash, or a string that is appropriately encoded (application/x-www-form-urlencoded or multipart/form-data). The headers should be a hash. The keys will automatically be upcased, with the prefix ‘HTTP_’ added if needed.

You can also perform POST, PUT, DELETE, and HEAD requests with #post, #put, #delete, and #head.



151
152
153
 
# File 'lib/action_controller/integration.rb', line 151

def get(path, parameters=nil, headers=nil)
  process :get, path, parameters, headers
end

#get_via_redirect(path, args = {}) ⇒ Object

Performs a GET request, following any subsequent redirect. Note that the redirects are followed until the response is not a redirect–this means you may run into an infinite loop if your redirect loops back to itself.



124
125
126
127
128
 
# File 'lib/action_controller/integration.rb', line 124

def get_via_redirect(path, args={})

  status
end

#head(path, parameters = nil, headers = nil) ⇒ Object

Performs a HEAD request with the given parameters. See get() for more details.



171
172
173
 
# File 'lib/action_controller/integration.rb', line 171

def head(path, parameters=nil, headers=nil)
  process :head, path, parameters, headers
end

#host!(name) ⇒ Object

Set the host name to use in the next request.

session.host! "www.example.com"



107
108
109
 
# File 'lib/action_controller/integration.rb', line 107

def host!(name)
  @host = name
end

#https!(flag = true) ⇒ Object

Specify whether or not the session should mimic a secure HTTPS request.

session.https!
session.https!(false)



91
92
93
 
# File 'lib/action_controller/integration.rb', line 91

def https!(flag=true)
  @https = flag        
end

#https? ⇒ Boolean

Return true if the session is mimicing a secure HTTPS request.

if session.https?
  ...
end

Returns:

  • (Boolean)

101
102
 
# File 'lib/action_controller/integration.rb', line 100

def https?

end

#post(path, parameters = nil, headers = nil) ⇒ Object

Performs a POST request with the given parameters. See get() for more details.



156
157
158
 
# File 'lib/action_controller/integration.rb', line 156

def post(path, parameters=nil, headers=nil)
  process :post, path, parameters, headers
end

#post_via_redirect(path, args = {}) ⇒ Object

Performs a POST request, following any subsequent redirect. This is vulnerable to infinite loops, the same as #get_via_redirect.

134
135
136
 
# File 'lib/action_controller/integration.rb', line 132

def post_via_redirect(path, args={})

  status
end

#put(path, parameters = nil, headers = nil) ⇒ Object

Performs a PUT request with the given parameters. See get() for more details.

162
163
 
# File 'lib/action_controller/integration.rb', line 161

def put(path, parameters=nil, headers=nil)
  process :put, path, parameters, headers
end

#redirect? ⇒ Boolean

Returns true if the last response was a redirect.

Returns:

  • (Boolean)

140
141
 
# File 'lib/action_controller/integration.rb', line 139

def redirect?
  status/100 == 3
end

#reset! ⇒ Object

Resets the instance. This can be used to reset the state information in an existing session instance, so it can be used from a clean-slate condition.

session.reset!
