Device and method for determining coverage rate information of increment codes

Abstract

The invention discloses a device and method for determining coverage rate information of increment codes. The method includes: adopting a code management device for acquiring increment change files ofto-be-tested version codes relative to base line version codes; acquiring the increment codes of the to-be-tested version codes relative to the base line version codes on the basis of the increment change files; subjecting the to-be-tested version codes to unit testing to obtain integral code coverage rate information; on the basis of the integral code coverage rate information and the incrementchange files, mapping change codes of the increment codes to row objects of an abstract syntax tree; performing traversal of the row objects of the abstract syntax tree, and determining characteristicinformation amount of the increment codes and covered characteristic information quantity of the increment codes from the row objects of the abstract syntax tree; dividing the characteristic information amount of the increment codes by the covered characteristic information quantity of the increment codes to obtain the coverage rate information of the increment codes. By adoption of the method, increment code testing efficiency and accuracy are improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to the field of computer network technology, and in particular to a method and device for determining coverage information of incremental codes. Background technique [0002] The product iteration of the Internet industry is getting faster and faster. In order to ensure the quality of the product, the role of unit testing cannot be underestimated. For legacy projects, a large amount of unit test code for legacy code is missing. The cost of unit test code that complements the original code is very high, and the effect is not significant. [0003] In this case, it is feasible to check and measure the coverage of the newly added code. However, the existing coverage statistics tools can only count the coverage of all codes by unit test cases, and developers and testers often focus on the coverage data of incremental codes. Three coverage indicators are commonly used for c...

AI Technical Summary

Problems solved by technology

But when there is such a situation in the source code that one line of statement is written in multiple lines of code, if an increment occurs in multiple lines of code, it is often not counted in the coverage result, which affects the accuracy of the result

In addition, some languages ​​are limited by coverage tools, and some coverage indicators are missing

For example, coverage, the most widely used language test coverage tool for python, cannot obtain function coverage

The missing coverage index also has a certain impact on the measurement of the coverage of the tested source file
