Using Tcl/Tk for an Automatic Test Engine

Test Automation Programming Interface with Object Controlled Authentication, TAPIoca, is a Tcl/Tk based automatic test environment. It grew out of the need to construct automatic tests at the system level that could send commands to a System Under Test (SUT), get responses from the SUT, and control signal generation equipment connected to the same SUT. Tcl/Tk was chosen as the basis for this automatic test environment because of the wealth and maturity of its "language" features, as well as its ease of extensibility.
