ABSTRACT:
In a method for testing computer code, each branch that occurs within the machine-readable code is located. A first tracepoint is placed immediately after the beginning of the branch and a second tracepoint at the target address of each branch, each tracepoint generating an indicator. When the machine-readable code with the tracepoints is executed on the target computer, the method identifies those indicators that have been generated by their corresponding tracepoints, thereby permitting determination of those branches that the program control flow has not passed through. The test cases are modified to exercise the previously omitted branches, and the converted code is re-executed, until all branches have been properly exercised. The tracepoints are automatically eliminated after they have performed their intended function.
