Abstract
The present invention provides a method to test a protocol stack operable to be loaded to a wireless terminal. This involves the creation of simulation scripts from prior test case logs associated with a prior test case executed on a physical wireless terminal. When the prior test case is failed on a physical device, the simulation scripts are used to locate and correct errors in protocol stack. The simulation scripts are then stored within and retrieved from a library. These simulations scripts are loaded within a simulation environment within computer systems such as a personal computer. The simulation scripts are executed on the protocol stack within the simulation environment to produce a set of results. These results are then compared to a reference log, wherein a favorable comparison indicates a satisfactory simulation. Should an unfavorable comparison result, the protocol stack may be revised. The above process may then be repeated on the revised protocol stacks following the detection, location and correction of errors within the protocol stack.
