We need to enable gcloud session testing on CI.

This would allow us to vet dependency updates for things like grpc (#5510)

looking at it. currently this fail because com.google.cloud.datastore.testing.LocalDatastoreHelper is starting some datastore using command line gcloud I'm trying a solution using a remote instance

So the exceptions reported are IOExceptions, connection refused.

This is because the com.google.cloud.datastore.testing.LocalDatastoreHelper class calls this method on com.google.cloud.testing.BaseEmulatorHelper to find a free port to start the server process on:

protected static int findAvailablePort(int defaultPort) {
try (ServerSocket tempSocket = new ServerSocket(0)) {
return tempSocket.getLocalPort();
} catch (IOException e) {
return defaultPort;
}
}

This won't work, as we discovered in the jetty-maven-plugin integration tests. You can't ask ServerSocket to find you an available port and just use the port number, you have to use the ServerSocket returned, otherwise the os may allocate that port to another user by the time you get around to trying to connect to it.

I've checked the latest available google code for the google-cloud-core jar (v 1.94.0) and this problem is still there.

Can you look into how we would dockerize this test instead, as that may avoid this problem.
