Class: ActionDispatch::Integration::Session

Overview

An instance of this class represents a set of requests and responses performed sequentially by a test process. Because 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 Session directly.

::ActionDispatch::Assertions - Included

::ActionDispatch::Assertions::RoutingAssertions - Included

#assert_generates

Asserts that the provided options can be used to generate the provided path.

#assert_recognizes

Asserts that the routing of the given path was handled correctly and that the parsed options (given in the expected_options hash) match path.

#assert_routing

Asserts that path and options match both ways; in other words, it verifies that path generates options and then that options generates path.

#method_missing

ROUTES TODO: These assertions should really work in an integration context.

#with_routing

A helper to make it easier to test different route configurations.

::ActionDispatch::Assertions::ResponseAssertions - Included

#assert_redirected_to

Asserts that the redirection options passed in match those of the redirect called in the latest action.

#assert_response

Asserts that the response is one of the following types:

#process(method, path, params: nil, headers: nil, env: nil, xhr: false, as: nil)

Performs the actual request.

  • method: The HTTP method (GET, POST, PATCH, PUT, DELETE, HEAD, OPTIONS) as a symbol.

  • path: The URI (as a ::String) on which you want to perform the request.

  • params: The HTTP parameters that you want to pass. This may be nil, a Hash, or a String that is appropriately encoded (application/x-www-form-urlencoded or multipart/form-data).

  • headers: Additional headers to pass, as a ::Hash. The headers will be merged into the Rack env hash.

  • env: Additional env to pass, as a ::Hash. The headers will be merged into the Rack env hash.

This method is rarely used directly. Use #get, #post, or other standard HTTP methods in integration tests. #process is only required when using a request method that doesn’t have a method defined in the integration tests.

This method returns the response status, after performing the request. Furthermore, if this method was called from an ::ActionDispatch::IntegrationTest object, then that object’s @response instance variable will point to a ::ActionDispatch::Response object which one can use to inspect the details of the response.

Example:

process :get, '/author', params: { since: 201501011400 }
