[0002] With the wide application of switches in industry and life, switches are strictly tested during the R&D stage to achieve close to the internal requirements of the product and realize the functions of the product. However, many test case design methods for switches are based on the division of equivalence classes. , combined design, orthogonal design and scenario design, etc., but there is no good test case design method that fits the switch state transition protocol

Abstract

The invention discloses a state machine-based test case design method applicable to a switch protocol. Through a function point in the switch protocol, whether a to-be-designed switch protocol belongs to a state transition class, if yes, all states near the function point are listed, a state conversion relationship is analyzed, a starting point and an ending point are determined, and a state transition map is obtained; and a main state path and all independent state path branches in the state transition map are listed, the independent state path branches and the main state path form N state conversion paths, and each state conversion path in the state transition map at least performs execution for one time. The state machine-based test case design method applicable to a switch protocol can be applicable to most protocols of the switch, detailed state conversion paths can be analyzed, leakage test can be prevented, case redundancy can be avoided, and the use coverage rate is improved.

Description

technical field [0001] The invention relates to the technical field of communication testing, in particular to a state machine-based test case design method suitable for switch protocols. Background technique [0002] With the wide application of switches in industry and life, switches are strictly tested during the R&D stage to achieve close to the internal requirements of the product and realize the functions of the product. However, many test case design methods for switches are based on the division of equivalence classes. , combined design, orthogonal design and scenario design, etc., but there is no good test case design method that fits the switch state transition protocol. [0003] Therefore, those skilled in the art have been devoting themselves to researching a most of the protocols suitable for switches, which can analyze the detailed state transition paths, prevent missed detection, avoid use case redundancy, and improve use case coverage. State machine test cas...
