Functions
bool	testsuite::AreTestpointsAvailable () noexcept
	Returns true if testpoints are available in runtime.

Macro Definition Documentation

TESTPOINT

#define TESTPOINT	(		name,
			json )

Send testpoint notification. Works only if testpoint support is enabled (e.g. in components::TestsControl), otherwise does nothing.

Example usage:

    TESTPOINT("simple-testpoint", [] {
        formats::json::ValueBuilder builder;
        builder["payload"] = "Hello, world!";
        return builder.ExtractValue();
    }());

async def test_basic(service_client, testpoint):
    @testpoint('simple-testpoint')
    def simple_testpoint(data):
        assert data == {'payload': 'Hello, world!'}
 
    response = await service_client.get('/testpoint')
    assert response.status == 200
    assert 'application/json' in response.headers['Content-Type']
    assert simple_testpoint.times_called == 1

Throws nothing if server::handlers::TestsControl is not loaded or it is disabled in static config via load-enabled: false.

Examples

postgresql/functional_tests/basic_chaos/postgres_service.cpp, samples/kafka_service/src/consume.cpp, samples/testsuite-support/src/tasks.cpp, samples/testsuite-support/src/testpoint.cpp, samples/ydb_service/components/federated_topic_reader.cpp, and samples/ydb_service/components/topic_reader.cpp.

TESTPOINT_CALLBACK

#define TESTPOINT_CALLBACK	(		name,
			json,
			callback )

Send testpoint notification and receive data. Works only if testpoint support is enabled (e.g. in components::TestsControl), otherwise does nothing.

Example usage:

    formats::json::ValueBuilder result;
 
    TESTPOINT_CALLBACK("injection-point", formats::json::Value(), [&result](const formats::json::Value& doc) {
        result["value"] = doc["value"].As<std::string>("");
    });

async def test_injection(service_client, testpoint):
    @testpoint('injection-point')
    def injection_point(data):
        return {'value': 'injected'}
 
    response = await service_client.get('/testpoint')
    assert response.status == 200
    assert 'application/json' in response.headers['Content-Type']
    assert response.json() == {'value': 'injected'}
 
    # testpoint supports callqueue interface
    assert injection_point.times_called == 1

Throws nothing if server::handlers::TestsControl is not loaded or it is disabled in static config via load-enabled: false.

TESTPOINT_CALLBACK_NONCORO

#define TESTPOINT_CALLBACK_NONCORO	(		name,
			json,
			task_processor,
			callback )

Same as TESTPOINT_CALLBACK but must be called outside of coroutine (e.g. from std::thread routine).

Throws nothing if server::handlers::TestsControl is not loaded or it is disabled in static config via load-enabled: false.

Definition at line 97 of file testpoint.hpp.

TESTPOINT_NONCORO

#define TESTPOINT_NONCORO	(		name,
			json,
			task_processor )

Same as TESTPOINT but must be called outside of coroutine (e.g. from std::thread routine).

Throws nothing if server::handlers::TestsControl is not loaded or it is disabled in static config via load-enabled: false.
