/**
* The test runs a number of times. In all cases it uses a valid self-signed certificate
* that is installed in the trust store (so is trusted) and the same cert is supplied
* by the server for its own identity. Two servers on two different ports are used
* on the remote end.
*
* The GOOD_CERT cert contains the correct hostname of the target server
* and therefore should be accepted by the cert checking code in the client.
* The BAD_CERT cert contains an invalid hostname, and should be rejected.
* The LOOPBACK_CERT cert contains an invalid hostname, but it also contains a
* subject alternative name for IP address 127.0.0.1, so it should be accepted
* for this address.
