def delete(action, *args)

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

def get(action, *args)
  res = process_with_kwargs("GET", action, *args)
  cookies.update res.cookies
  res
end

Simulate a GET request with the given parameters.

  • action: The controller action to call.

  • 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.

You can also simulate POST, PATCH, PUT, DELETE, and HEAD requests with post, patch, put, delete, and head. Example sending parameters, session and setting a flash message:

get :show,
  params: { id: 7 },
  session: { user_id: 1 },
  flash: { notice: 'This is flash message' }

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

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.
