public

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

action: The controller action to call.
method: Request method used to send the HTTP request. Possible values are GET, POST, PATCH, PUT, DELETE, HEAD. Defaults to GET. Can be a symbol.
params: The hash with HTTP parameters that you want to pass. This may be nil.
body: The request body with 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.
format: Request format. Defaults to nil. Can be string or symbol.
as: Content type. Defaults to nil. Must be a symbol that corresponds to a mime type.

Example calling create action and sending two params:

process :create,
  method: 'POST',
  params: {
    user: { name: 'Gaurish Sharma', email: '[email protected]' }
  },
  session: { user_id: 1 },
  flash: { 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.
