Java unit test case generation method and device

Abstract

The invention provides a Java unit test case generation method and device, which can be applied to the financial field. The method comprises the following steps: generating a service AST library and a test AST library according to an obtained service source code and a corresponding test code; matching the service AST in the service AST library with the test AST in the test AST library, and screening the service AST which is not successfully matched; generating a test code for the service AST which is not successfully matched; generating a corresponding test AST, and filling the test AST into a test AST library; and traversing the service AST library and the test AST library to check whether the test coverage rate is met. According to the method, the unit test case meeting the specification can be automatically generated, various index requirements such as the code line coverage rate and the change coverage rate are met, iteration is carried out on the basis of existing test codes, and the original test case is not affected.

Description

technical field [0001] The application belongs to the technical field of system testing, and in particular, relates to a method and device for generating Java unit test cases. Background technique [0002] Unit testing is an important part of the UTDD approach. At present, unit testing has the problem of cumbersome and complicated writing of test codes, and developers often have to write test codes that are several times the amount of business code. Moreover, the structure of many complex projects is also very complicated, the code organization is intertwined, and the commonly used mock tools are difficult to use. It is not easy to write a unit test case that is correct, fully functional and has a coverage rate. [0003] Currently, the automatic generation frameworks for unit test cases on the market only support the generation of simple unit tests, and cannot be compatible with more scenarios, nor do they support complex scenarios at the project level.
