Generation method and system of test cases

Abstract

The present invention discloses a generation method of test cases. The generation method comprises compiling source program by using a compiler, and generating stub source program; graphically displaying the source program by using the compiler, obtaining a syntax tree intermediate file, analyzing the syntax tree intermediate file, and generating a flow chart of the source program; calculating the flow chart, and obtaining a target path set of the source program; and generating the test cases by using a genetic algorithm according to the stub source program and the target path set. According to the method, the test cases can be automatically generated, so that generation of the test cases can be more user-friendly, manpower is saved, the method is simple and easy to use with graphic combination, cost is saved, and efficiency is improved. The present invention also discloses a generation system of test cases.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a method and system for generating test cases. Background technique [0002] Program testing exists in the entire life cycle of the program development process, the workload is heavy, and many various resources are needed in the process of testing. Because the design, execution, and analysis of test cases are very cumbersome, it takes a lot of time, and the efficiency is very low, so the cost of testing is very high. In the program development work, the proportion of program testing work is very high, usually reaching about 40%, and some with high requirements even reach 60%. Because most of the operations and processes of program testing are repetitive and massive, automation methods can be applied to program testing in the process of program development. The automation of testing can not only reduce many meaningless workloads of testers, but also improve the utilizati...

Problems solved by technology

However, in some current testing tools (such as testbed, c++test), the effect of automatic test case generation and test coverage are not ideal. In the development of most program products, many so-called automated testing tools are actually None of them can be fully automated, especially in the aspect of test case generation, mainly using manual design mode to complete product testing

The existing test cases are mainly black-box tests, and the instrumentation of the program is mainly manual, which is inefficient and prone to errors. To address these shortcomings
