Detailed Description

Live Ethernet integration tests for DCP using AsioEthernetSocket.

Exercises the DCP protocol implementation together with the real Ethernet packet transport. The transport is intentionally independent of the operating-system packet API.

Set PROFINET_TEST_INTERFACE to select the Ethernet interface used by these tests.

Function Documentation

TEST_F() [1/4]

TEST_F	(	DcpAsioIntegrationTests	,
		GetParamPerformsAsioRoundTrip
	)

Test:

Verifies that GetParam performs a complete DCP GET request and response exchange using two real Asio raw Ethernet transports.

DCP::GetParam() -> request transmitted -> peer receives request -> peer sends response -> controller receives matching response -> parameter returned More valueable then only AsioEthernetSocket::Send()
