Method and system for automatically backtracing through a testcase file. First
the testcase file is accessed. Next, a start line identifier for specifying an
instruction line in the testcase file at which to begin processing is received.
The instruction line in the testcase file that is specified by the start line identifier
is processed first. The previous instruction lines in the testcase file are then
processed in a sequential fashion until the beginning of the testcase file is reached.
