Visualized and dynamic testing rule creating method oriented to parallel tests of safety demanding system

Abstract

The invention discloses a visualized and dynamic testing rule creating method oriented to parallel tests of a safety demanding system and belongs to the field of system testing. The method includes defining an isomorphic storage data structure of a type tree of a five-grade structure for all type tests of the safety demanding system; creating a current type tree and a comparison type tree according to the type tree; performing type tree copying or single node copying according to test needs; when nodes in the comparison type tree are added into the current type tree, judging whether homonymic nodes positioned under same subsystem nodes or test item nodes and identical in logic relation exist or not, wherein as for the homonymic nodes, re-adding is not performed. In the method, node operations on the current type tree are all recorded in a buffering area, and redundancy eliminating operation is performed before the node operations are submitted to a database. By the method, a universal storage structure for multi-type tests is designed, so that compiling time of testing rules and workload of testing personnel in multi-type spacecraft tests are reduced, and testing efficiency is improved.

Description

technical field [0001] The invention belongs to the field of system testing, and relates to a method for visually and dynamically constructing test rules for multi-type parallel testing in safety-critical system testing. Background technique [0002] In the safety-critical system test, the test specification is a set of test instructions in the safety-critical system test, which is written by the tester using basic test instructions according to the test cases. Since safety-critical systems are complex systems, they are generally composed of subsystems, modules, and components. Each layer involves a large number of attributes, which are the basic components of test instructions. Therefore, the test rules need to be written by testers step by step from subsystem, test project, and test sub-item. Each level of nodes needs to write a large number of attributes and attribute values. Spacecraft system is a typical safety-critical system, so it is very necessary to use it as a t...

Problems solved by technology

In multi-model batch testing, if each model still manually edits test items and test sub-items, it will undoubtedly increase manpower consumption and time consumption, and this method is not feasible
