An ultrasonic apparatus reliability testing method and testing system

Abstract

The invention provides an ultrasonic apparatus reliability testing method and testing system. The method comprises the steps of extracting behavior action in a code of a to-be-tested product; retrieving an instruction invoking mapping table according to the behavior action and generating an execution function; encapsulating the execution results of the execution function into a testing program and converting the same into a plurality of testing vectors; extracting testing vectors associated with user interaction from the testing vectors to establish a formal rule database associated with user interaction behavior; randomly selecting testing vectors to generate random testing vector sequences and performing function classification on the testing vectors and the random testing vector sequences, matching the testing vectors and/or random testing vector sequences subjected to the function classification and associated with user interaction with the formal rule database; after the matching is successful, determining that the current testing vectors and/or random testing sequences cover user requirements and continuing tests. The method and the system optimize testing sequence generate, remove redundant testing sequences and greatly shorten testing time.

Description

technical field [0001] The invention belongs to the technical field of medical ultrasonic diagnosis, and in particular relates to a testing method and testing system for the reliability of ultrasonic equipment. Background technique [0002] Ultrasound imaging has become one of the most widely used clinical diagnostic tools because of its non-invasive, real-time, convenient operation, and low price. [0003] In the reliability test of ultrasonic equipment, it usually includes the test of software and hardware. The coverage test algorithm is used to obtain the test factor set through equivalence class division, and then the coverage table is generated through the combination test to verify the reliability of software and hardware. ; The combined coverage table generated by this test algorithm through the equivalence class partition test set has a lot of redundant data, and the large amount of data generated is not suitable for the implementation of automated testing in agile i...

[0003] In the reliability test of ultrasonic equipment, it usually includes the test of software and hardware. The coverage test algorithm is used to obtain the test factor set through equivalence class division, and then the coverage table is generated through the combination test to verify the reliability of software and hardware. ; The combined coverage table generated by this test algorithm through the equivalence class partition test set has a lot of redundant data, and the large amount of data generated is not suitable for the implementation of automated testing in agile iterative development. At the same time, using this coverage test algorithm can only obtain Partial coverage test effect, in the annual development cycle of new product functions, has limited improvement to the reliability of the overall system
