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

Abstract

The present application discloses a method and a device for determining coverage information of incremental codes. The method includes: using a code manager to obtain an incremental change file of the code of the version to be tested relative to the code of the baseline version; based on the incremental change file, obtaining the incremental code of the code of the version to be tested relative to the code of the baseline version; Test to get the overall code coverage information; based on the overall code coverage information and the incremental change file, map the changed code lines of the incremental code to the line objects of the abstract syntax tree; traverse the line objects of the abstract syntax tree, from the abstract syntax tree Determine the total number of feature information of the incremental code and the number of covered feature information of the incremental code in the row object; divide the number of covered feature information of the incremental code by the total number of feature information of the incremental code to obtain the coverage rate of the incremental code information. The method can improve the efficiency and accuracy of testing incremental codes.

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...
