build_response(klass)

Source: show 

# File actionpack/lib/action_controller/test_case.rb, line 564
def build_response(klass)
  klass.create
end

controller_class_name()

Source: show 

# File actionpack/lib/action_controller/test_case.rb, line 524
def controller_class_name
  @controller.class.anonymous? ? "anonymous" : @controller.class.controller_path
end

delete(action, **args)

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

Source: show 

# File actionpack/lib/action_controller/test_case.rb, line 439
def delete(action, **args)
  process(action, method: "DELETE", **args)
end

generated_path(generated_extras)

Source: show 

# File actionpack/lib/action_controller/test_case.rb, line 528
def generated_path(generated_extras)
  generated_extras[0]
end

get(action, **args)

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.

Source: show 

# File actionpack/lib/action_controller/test_case.rb, line 413
def get(action, **args)
  res = process(action, method: "GET", **args)
  cookies.update res.cookies
  res
end

head(action, **args)

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

Source: show 

# File actionpack/lib/action_controller/test_case.rb, line 445
def head(action, **args)
  process(action, method: "HEAD", **args)
end

patch(action, **args)

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

Source: show 

# File actionpack/lib/action_controller/test_case.rb, line 427
def patch(action, **args)
  process(action, method: "PATCH", **args)
end

post(action, **args)

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

Source: show 

# File actionpack/lib/action_controller/test_case.rb, line 421
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)

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: 'user@example.com' }
  },
  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.
