The wss endpoint with 9443 port seems to have issue according to #123. By simply adjusting the default endpoint the problem can be fixed.
The mock module has deprecated since mockito 1.0.0. Upgraded the dependencies and affected test module. Some other dependencies are also safely upgraded.
FuturesGeneral::ping() doesn't work and since there lacks a test for that, this issue has not been discovered. Added a test module for that and fixed the function.
