Overview

This class represents a series of requests issued to a Rack app, sharing a single cookie jar

Rack::Test::Session's methods are most often called through Rack::Test::Methods, which will automatically build a session when it's first used.

Constructor Details

#initialize(mock_session) ⇒ Session

Creates a Rack::Test::Session for a given Rack app or Rack::MockSession.

Note: Generally, you won't need to initialize a Rack::Test::Session directly. Instead, you should include Rack::Test::Methods into your testing context. (See README.rdoc for an example)

  uri = parse_uri(uri, env)
  env = env_for(uri, env.merge(method: verb.to_s.upcase, params: params))
  process_request(uri, env, &block)
end

#delete(uri, params = {}, env = {}, &block) ⇒ Object

Issue a DELETE request for the given URI. See #get

def digest_authorize(username, password)
  @digest_username = username
  @digest_password = password
end

#env(name, value) ⇒ Object

Set an env var to be included on all subsequent requests through the session. Use a value of nil to remove a previously configured env.

#follow_redirect! ⇒ Object

Rack::Test will not follow any redirects automatically. This method will follow the redirect returned (including setting the Referer header on the new request) in the last response. If the last response was not a redirect, an error will be raised.

  # Compute the next location by appending the location header with the
  # last request, as per https://tools.ietf.org/html/rfc7231#section-7.1.2
  # Adding two absolute locations returns the right-hand location
  next_location = URI.parse(last_request.url) + URI.parse(last_response['Location'])

    request_method, next_location.to_s, params,
    'HTTP_REFERER' => last_request.url,
