// Test matrix. Originator behavior defined by rows, receiever by columns.
// Currently the p2ptransportchannel.cc (specifically the
// P2PTransportChannel::OnUnknownAddress) operates in 2 modes depend on the
// remote candidates - ufrag per port or shared ufrag.
// For example, if the remote candidates have the shared ufrag, for the unknown
// address reaches the OnUnknownAddress, we will try to find the matched
// remote candidate based on the address and protocol, if not found, a new
// remote candidate will be created for this address. But if the remote
// candidates have different ufrags, we will try to find the matched remote
// candidate by comparing the ufrag. If not found, an error will be returned.
// Because currently the shared ufrag feature is under the experiment and will
// be rolled out gradually. We want to test the different combinations of peers
// with/without the shared ufrag enabled. And those different combinations have
// different expectation of the best connection. For example in the OpenToCONE
// case, an unknown address will be updated to a "host" remote candidate if the
// remote peer uses different ufrag per port. But in the shared ufrag case,
// a "stun" (should be peer-reflexive eventually) candidate will be created for
// that. So the expected best candidate will be LUSU instead of LULU.
// With all these, we have to keep 2 test matrixes for the tests:
// kMatrix - for the tests that the remote peer uses different ufrag per port.
// kMatrixSharedUfrag - for the tests that remote peer uses shared ufrag.
// The different between the two matrixes are on:
// OPToCONE, OPTo2CON,
// COToCONE, COToADDR, COToPORT, COToSYMM, COTo2CON, COToSCON,
// ADToCONE, ADToADDR, ADTo2CON,
// POToADDR,
// SYToADDR,
// 2CToCONE, 2CToADDR, 2CToPORT, 2CToSYMM, 2CTo2CON, 2CToSCON,
// SCToADDR,
// TODO: Fix NULLs caused by lack of TCP support in NATSocket.
// TODO: Fix NULLs caused by no HTTP proxy support.
// TODO: Rearrange rows/columns from best to worst.
// TODO(ronghuawu): Keep only one test matrix once the shared ufrag is enabled.
