Don't check what is sent back. The point is that the client should be fully initialized at this point.
We can't ensure using metrics that the "check" connection is gone since in some tests, the server is started and clients auto-reconnect to it.
For tests that depend on the number of clients connected (such as the monitor one), have specific code for those tests.
- The raw connection used to check that the server is started now consumes the INFO and sends PING and consumes PONG before returning.
- The route test needs to make sure that the client connection has client id 2. Using PING/PONG before creating route connection to make sure of that.
* Add server.GetListenEndpoint() to return options' host and port when server is ready to accept client connections. The server can be asked to pick a random port. This function returns a string of the form "host:port" with the port selected by the net.Listen() call.
* Replace the use of server.Addr() with above function to connect to the starting server (using net.Dial) to check for success. The original issue was that, when no hostname is specified in the configuration, the server uses 0.0.0.0 for the listen address. However, server.Addr() would return "[::]", even on a machine with IPv6 disabled, which would cause the net.Dial call to fail with "network unreachable".
We would get failures on Travis, I would think because of small TLS timeout. Increase (or set) the TLS timeout to 2 seconds in most configuration files. Update tests that relied on the original value.
* There was a bug in the send loop (use of 1 instead of i)
* On Windows specifically, the test did not exit without explicit closing of the connections (I don't think we should have to do that). This behavior combined with the send loop bug would cause this test to consume all memory on the machine.
Without the server fix, tls_test.go would likely report an error. The server would show a parser error with protocol snippet containing "random" bytes, likely encrypted data.
