Simulate a DELETE request with the given parameters and set/volley the response. See get for more details.

def delete(action, *args)
  process(action, "DELETE", *args)
end

#get(action, *args) ⇒ Object

Simulate a GET request with the given parameters.

  • action: The controller action to call.

  • parameters: 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).

  • 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.

You can also simulate POST, PATCH, PUT, DELETE, and HEAD requests with post, patch, put, delete, and head.

Note that the request method is not verified. The different methods are available to make the tests more expressive.

def post(action, *args)
  process(action, "POST", *args)
end

#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.
