A method and apparatus for point-to-point interconnect testing are described. In one embodiment, the method includes the determination of an expected behavior of a point-to-point link according to initial link training/configuration values of the link. The expected link behavior is determined according to link behavior during initial link configuration. A respective test value may be driven on at least one lane of the link to emulate lane break/degradation conditions during retraining of the link in response to a link reset. In one embodiment, an actual behavior of the link may be determined according to the behavior of the link during retraining of the link as lane break/degradation values are driven over the link. In one embodiment, a lane break/degradation condition is detected if the expected link behavior does not match the actual behavior of the link. Other embodiments are described and claimed.
