The traditional software testing method is mostly dependent on direct analysis and instrumentation of source codes, so that the risk of core code leakage exists, and the testing personnel are required to have deep code understanding capability, so that the testing cost is high and the period is long. Meanwhile, the difference between the test environment and the real running environment often makes part of deep logic defects and dynamic interaction problems difficult to be effectively exposed. Therefore, how to realize deep and efficient verification of the internal states and logic behaviors of complex software on the premise of ensuring the code security has become a technical problem to be solved in the field.
