#get(action, **args) ⇒ Object

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 a PATCH request with the given parameters and set/volley the response. See ‘get` for more details.

# File 'lib/action_controller/test_case.rb', line 441

def patch(action, **args)
  process(action, method: "PATCH", **args)
end

#post(action, **args) ⇒ Object

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

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

#process(action, method: "GET", params: nil, session: nil, body: nil, flash: {}, format: nil, xhr: false, as: nil) ⇒ Object

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.

It’s not recommended to make more than one request in the same test. Instance variables that are set in one request will not persist to the next request, but it’s not guaranteed that all Rails internal state will be reset. Prefer ActionDispatch::IntegrationTest for making multiple requests in the same test.

Note that the request method is not verified.
