Automatic test case generation method

Abstract

The automatic test case generation method disclosed by the invention is high in test efficiency, strong in adaptability and high in reusability. According to the technical scheme, the method comprises the steps that a state diagram test model is converted into a binary state tree on the basis of a workflow test model, and parameters and judgment conditions in an expression input by a user or an expression defined by the user according to the requirement of the user are extracted in combination with boundary values and equivalence classes on the basis of the binary state tree; a target path existing in the test model is obtained through a graph traversal algorithm, all states are traversed to edges of the states, sequence tables of all nodes in the binary state tree are obtained respectively, values are analyzed through boundary values and equivalence classes to obtain test items, an expression defined by a user is analyzed, judgment conditions of parameters are obtained, a value corresponding to the judgment condition is generated, a test case is automatically generated, and finally reverse verification isperformed according to the generated test case to judge whether the case is correct or not.

Description

technical field [0001] The invention relates to model testing in the field of software testing, such as flow charts, judgment tables, and state transition diagrams. After the user builds the model correctly, test cases can be automatically generated. Assist testers to complete the test work. Background technique [0002] With the advancement of technology, the development of software. All kinds of software are integrated into people's daily life. Today, with the emergence of a large number of software, higher security and stability are also proposed for the software itself. Before a piece of software goes online, a lot of testing needs to be done in order to improve the quality of the software. Software testing is an integral part of the software development cycle. Yet software testing costs more than half of the cost of software development. Software testing is a very resource-intensive activity, and one of the more important tasks is to find a suitable set of tests f...

AI Technical Summary

Problems solved by technology

After receiving the test task and designing the test case, the tester finds that the actual content of the software does not match the development requirements, and other problems may be found during the execution of the use case, resulting in the need to redesign the use case and execute it again

It makes testers need to repeat work and is inefficient

[0005] (2) Manual design of test cases limits the thinking of testers

[0006] (3) The complexity of software is gradually increasing, and users' requirements for the reliability of complex systems are gradually increasing
