DEPRECATION WARNING:

`ActionDispatch::IntegrationTest` HTTP request methods will accept only
the following keyword arguments in future Rails versions:
params, headers, env, xhr, as

Examples:

    get '/profile',
      params: { id: 1 },
      headers: { 'X-Extra-Header' => '123' },
      env: { 'action_dispatch.custom' => 'custom' },
      xhr: true,
      as: :json
