The test is somewhat similar to tst_QSslSocket but is smaller (in scope, will
grow in future), it has no QTcpSocket/QAbstractSocket-specific things and
has more DTLS-specific code. At the moment it does not use our network
test server, all work is done in the same process with two QUdpSockets
and two QDtls objects. We test (both on client/server ends):
- parameters validation (for all functions that do this) and
the correctness of error codes/handshake states
- handshake procedure (with/out certificates and with pre-shared keys)
- timeouts and re-transmissions during (D)TLS handshake
- peer verification (and related verification errors)
- aborted/resumed handshake
- encrypted I/O
- DTLS shutdown
For now, this test is OpenSSL-only.
