Program flow graph oriented analysis of coverage and time performance

In order to track the dynamic information of the tested system, get the analysis of coverage and time performance, It is critical to optimize the test technique efficiency. With the help of instrumentation to identify program block, this paper proposed an algorithm IPFG for constructing program flow graph, which is based on analyzing instrumentation information derived from program block This approach comes up with a dynamic test framework based on program PGF instrumentation pretreatment. Experimental results show that, by using this framework to fulfill test instrumentation, coverage analysis and time performance analysis, the algorithm prove to be of high efficiency and accuracy.
