 6. If you want to run tests manually using the TANGO bindings without requiring a live machine you can also install the the Dummy TANGO control system available in tests/dummy-cs/tango. It is a simple emulation that allows to check the interface to the control system. The implemented control system doesn't do anything but it is only intended for tests during the development.
