technology. Most of today's coverage testing tools use the code plug-in technology. It inserts some probes in the program to ensure the original logic integrity of the program to be tested, and throws the program running feature data through the execution of the probe. Through the analysis of the data, the program control flow and data flow information can be ob

Task:control Flow oriented Coverage Test proceduresIn the so-called branch coverage test, the test case quantity for a program P is compiled so, each edge of the control Flow graph of P (see, for example, Fig. 1:you already know an equivalent representation as a program flowchart) at least Once, so all condition/branch at least once to true and (possibly in another test case) are evaluated too wrong at LEAs

when I tried to investigate a defect, usually the first thing that I want to verify is the "RunTime" execution flow. and if the "RunTime" flow didn't match the "expected" flow, I wocould be very close to the root cause of a defect. however, sometimes it's not very easy to tell the "real/RunTime" execution flow (especially when you can't attach your debugger to the target assembly, or when the defect can't be reproduced stably ). I used to add more debug info output to the logs to help me out, an
