Software dynamic testing operating data extracting method

The invention discloses a software dynamic testing operating data extracting method. The method comprises the following steps that a garrison process calls and starts a tested program through a system; when the tested program operates to a preset data monitoring point, signals are transmitted to the garrison process; after the garrison process saves sites, the tested program is hung up, and a routine is searched for in a data acquisition processing routine vector table according to the types of the received signals; the searched processing routine is called by the garrison process, and after specific operating data of the current position are obtained, data obtaining completion signals are transmitted to the garrison process; after the garrison process receives the obtaining completion signals, the sites are restored, and the tested program continues to operate. According to the method, code instrumentation is not needed, the code scale of the tested program will not be enlarged, operation efficiency of the tested program is not influenced, dependency on a hardware platform is avoided, the data are rich in type and can be obtained accurately in real time, and the method has high universality.
