Abstract

Electronic test system including hardware and software components and method of use of same which provide obsolescence mitigation. A set of governing rules for the system is defined and a test program test (TPS) is created to enable units to be tested. When a new component is introduced into the system, the change is detected and a new TPS is created. If the new TPS complies with the rules, testing using the new TPS is possible. If not, a determination is made as to whether any component of the TPS is obsolete and if not, the units can be tested using the new TPS without redefining the rules. When a component of the TPS is obsolete, the rules are reviewed to ascertain the effect of the removal of the component and optionally redefined to enable the new component to be used in combination with the remaining components.

12. The method of claim 1, wherein when the new TPS is determined not to comply with the rules, determining whether any component of the TPS has been rendered obsolete and if not, enabling testing of the units using the new TPS without redefining the rules;

and when a component of the TPS has been rendered obsolete, reviewing the rules to ascertain the effect of the removal of the component.

13. The method of claim 12, further comprising removing the obsolete component from the system.
