23/// @brief Handler that allows to control the behavior of server from tests,
24/// and @ref scripts/docs/en/userver/functional_testing.md "functional tests with testsuite"
25/// in particular.
26///
27/// It is highly recommended to disable this handle in production via the
28/// @ref userver_components "load-enabled: false" option.
29///
30/// The component must be configured in service config.
31///
32/// ## Static options:
33/// Aside from @ref userver_http_handlers "common handler options" component
34/// has the following options:
35///
36/// Name | Description | Default value
37/// ---- | ----------- | -------------
38/// testpoint-url | an URL that should be notified in the TESTPOINT_CALLBACK and TESTPOINT_CALLBACK_NONCORO macros | -
39/// skip-unregistered-testpoints | do not send testpoints data for paths that were not registered by `testpoint-url` | false
40/// testpoint-timeout | timeout to use while working with testpoint-url | 1s
41///
42/// ## Static configuration example:
43///
44/// @snippet components/common_server_component_list_test.cpp Sample tests control component config
45///
46/// ## Scheme
47/// Main user of the scheme is the pytest_userver.client.Client python class.
48/// In particular:
49/// @code
50/// {
51/// "action": "run_periodic_task" | "suspend_periodic_tasks" | "write_cache_dumps" | "read_cache_dumps" | "metrics_portability"
52/// "testpoints": [<list of testpoints to register>]
53/// "reset_metrics": true | false
54/// "mock_now": <time in utils::datetime::Stringtime() acceptable format>
55/// "invalidate_caches": <...>
56/// "socket_logging_duplication": true | false
57/// <...>
58/// }
