Method: ActionController::TestCase::Behavior#process

Defined in:
lib/action_controller/test_case.rb

#process(action, http_method = 'GET', *args) ⇒ Object

Simulate a HTTP request to action by specifying request method, parameters and set/volley the response.

  • action: The controller action to call.

  • http_method: Request method used to send the http request. Possible values are GET, POST, PATCH, PUT, DELETE, HEAD. Defaults to GET.

  • parameters: The HTTP parameters. This may be nil, a hash, or a string that is appropriately encoded (application/x-www-form-urlencoded or multipart/form-data).

  • session: A hash of parameters to store in the session. This may be nil.

  • flash: A hash of parameters to store in the flash. This may be nil.

Example calling create action and sending two params:

process :create, 'POST', user: { name: 'Gaurish Sharma', email: '[email protected]' }

Example sending parameters, nil session and setting a flash message:

process :view, 'GET', { id: 7 }, nil, { notice: 'This is flash message' }

To simulate GET, POST, PATCH, PUT, DELETE and HEAD requests prefer using #get, #post, #patch, #put, #delete and #head methods respectively which will make tests more expressive.

Note that the request method is not verified.
