1. A method for open and short testing an integrated circuit, the method comprising: engaging an integrated circuit testing module with an integrated circuit testing apparatus, the integrated circuit testing module having an integrated circuit to be tested, a first set of contact points, and a second set of contact points, wherein the first set of contact points are electrically coupled to the pins of the integrated circuit, and wherein contact points of the second set are aligned in contact pairs, the contact pairs being aligned to allow a first pin of the integrated circuit to be at least one of disconnected from any signal on the integrated circuit testing module or electrically shorted to at least one of a second pin of the integrated circuit, a ground connection, or a power connection;engaging a first probe of the integrated circuit testing apparatus onto at least one of the contact points of the first set of contact points;controllably engaging at least one of a second probe of the integrated circuit testing apparatus onto at least one contact pair of the integrated circuit testing module, thereby creating an electrical short between the at least two contact points of the second set; andproviding an electrical stimulus to the integrated circuit testing module. 2. The method as described in claim 1, further comprising: determining if the response of the integrated circuit is within an acceptable range of outputs given the input stimulus and the configuration of the at least one of the second probe. 3. The method as described in claim 2, further comprising: disengaging the integrated circuit testing module from the integrated circuit testing apparatus, and reengaging a second integrated circuit testing module when it is determined that the response of the integrated circuit is not within an acceptable range of outputs. 4. The method as described in claim 1, wherein the integrated circuit testing module further includes a third set of contact points and the integrated circuit testing apparatus further includes a cable to engage the third set of contact points of the integrated circuit testing module. 5. The method as described in claim 4, wherein the cable is a ribbon cable. 6. The method as described in claim 4, wherein the electrical stimulus is provided to the integrated circuit testing module via the cable. 7. The method as described in claim 1, wherein engaging the integrated circuit with the integrated circuit testing module comprises permanently attaching the integrated circuit to the integrated circuit testing module. 8. The method as described in claim 1, wherein engaging the integrated circuit with the integrated circuit testing module comprises electrically coupling the pins of the integrated circuit to the first set of contact points. 9. The method as described in claim 1, wherein the first pin of the integrated circuit and the second pin of the integrated circuit are adjacent. 10. The method as described in claim 1, further comprising: measuring a response of the integrated circuit via the first probe. 11.

The system as described in claim 11, wherein the first probe has an electrically conductive tip. 13. The system as described in claim 11, wherein the first probe is a fixed-location, spring-based probe. 14. The system as described in claim 11, wherein the second probe has an electrically conductive malleable tip. 15. The system as described in claim 11, wherein the second probe is pneumatically actuated. 16. The system as described in claim 11, wherein the second set of contact points are aligned in contact pairs. 17. The system as described in claim 16, wherein the contact pairs form a square separated by a saw tooth shaped gap. 18. A method for open and short testing of an integrated circuit, the method comprising: engaging an integrated circuit testing module with an integrated circuit testing apparatus, the integrated circuit testing module having an integrated circuit to be tested, a first set of contact points, a second set of contact points, and a third set of contact points, wherein the first set of contact points are electrically coupled to the pins of the integrated circuit, and wherein contact points of the second set are aligned in contact pairs, the contact pairs being aligned to allow a first pin of the integrated circuit to be at least one of disconnected from any signal on the integrated circuit testing module or electrically shorted to at least one of a second pin of the integrated circuit, a ground connection, or a power connection;engaging a first probe of the integrated circuit testing apparatus onto at least one of the contact points of the first set of contact points;controllably engaging at least one of a second probe of the integrated circuit testing apparatus onto at least one contact pair of the integrated circuit testing module, thereby creating an electrical short between the at least two contact points of the second set;engaging a cable of the integrated circuit testing apparatus on to the third set of contact points;providing an electrical stimulus to the integrated circuit testing module via at least one of the cable or the first probe;measuring a response of the integrated circuit via the first probe;determining if the response of the integrated circuit is within an acceptable range of outputs given the input stimulus and the configuration of the at least one of the second probe; anddisengaging the integrated circuit testing module from the integrated circuit testing apparatus when it is determined that the response of the integrated circuit is not within an acceptable range of outputs, and engaging a second integrated circuit testing module. 19. The method as described in claim 18, wherein at least one of the second probe has an electrically conductive malleable tip. 20. The method as described in claim 18, wherein engaging and disengaging the integrated circuit testing module into and out of the integrated circuit testing apparatus comprises robotically moving at least one of the integrated circuit testing module or the integrated circuit testing apparatus.
