Testing a TR 069 CPE device

Hi All,
I am new to TR 069.Scope of our project is to develop a CPE
stack to communicate with ACS.I want to do testing for the entire
system.Is there any testing toll available for this.What will be the
scope of testing in that case.I tried to test the CPE methods through
gatespace but i found only some mandatory methods.I think we can get
only single response at a time when testing through gatespace.Could
anybody help me on this?...

regards,
Rachrita
