And manually triggering a dotting action, and executing a corresponding service scene trigger log reporting mechanism according to the point change of the point. And acquiring a log reported by the point location. And inquiring the logs reported in the last step from a database stored in the dotting logs. The log information is collated, i.e., the fetched log is compared to the expected log.

According to the embodiment, when the dotting action is triggered, manual triggering is needed, the number of requests caught from the beginning of packet catching to the triggering of the dotting logic is large, the triggered dotting logic is not only one point, and human resources are wasted by screening. If the requested data is screened based on the platform, time is consumed seriously, and time is wasted.

Based on this, the present disclosure provides a method and an apparatus for checking a buried point log. The test case corresponding to the target point is automatically obtained by setting a rule for the target point, and the embedded point log of the target point is automatically checked, so that a check result of the embedded point log is obtained, and time, human resources and service handover cost are saved.
