Abstract

The present invention proposes a coverage test method and system, which includes: compiling the source code, inserting probe functions into each piece of code; recording the position information of all probe functions; running the program, recording the counting information of the probe functions; Generate the first coverage information according to the position information of the probe function in the running program and the count information of the corresponding probe function; generate the second coverage information according to the position information of the probe function in the program that has not been called; The first coverage information is combined with the second coverage information, and the final coverage result is obtained through calculation. The invention more accurately and objectively reflects the real coverage rate of the program code, and is suitable for the test of background service programs.

Description

technical field [0001] The invention relates to software testing technology, in particular to a method and system for testing the coverage rate of software codes. Background technique [0002] In the quality assurance system of C / C++ software development, coverage (the operating ratio of the code in the software) test is usually an effective means of finding problems. Through the analysis of code coverage, you can quickly locate which codes are not running , so as to construct corresponding test cases to cover these codes to find errors in software design. [0003] At present, the open source gcov tool is widely used in software code coverage testing. The gcov tool is a tool for detecting code coverage integrated in gcc (GNU Compiler Collection, GUN Compiler Suite). It passes through the compilation phase (that is, compiling the source code into Executable code), insert a probe function into the source code (inserting a probe function is also called stub, which is used to i...
