Abstract
A method is presented for recording and injecting a fault event during execution of a computer program. The method may include detecting a method call event during execution of the program, incrementing a counter to produce a counter value, and determining, based on a program execution state, a fault event to be generated. The fault event may be associated with a fault event type. The fault event type and the counter value may be stored, and the fault event may be generated. A second method call event may be detected during execution of the program and a second counter may be incremented, producing a second counter value. A previously-generated fault event associated with a counter value matching the second counter value may be identified, and the previously-generated fault event may be generated.
