System and method for realizing coverage rate test

Abstract

The invention discloses a system and a method for realizing coverage rate test, which are applicable to various operating systems for counting coverage rate. The system comprises a source code analyzer, a code implanting device, a code dotting module and a calculation module. The source code analyzer is connected with a tested module and used for performing source code analysis to the tested module and counting the amount of command to be tested in the tested module; the code implanting device is connected with the tested module and used for inserting code dotting program before the command to be tested in the tested module and recoding the source code in which the code dotting program is inserted; the code dotting module is connected with the tested module and used for recording the transferring numbers of the code dotting program; and the calculation module is connected with the source code analyzer and the code dotting module and used for calculating the ratio between the transferring numbers of the dotting program and the total amount of the command and outputting the ratio. The invention performs coverage rate test on the basis of source code analysis, thereby being applicable to different operating systems and being improved in the compatible and practical performance.

Description

Technical field [0001] The invention relates to a white box testing technology in the communication field, and in particular to a coverage testing system and method. Background technique [0002] White box testing, also called structural testing or logic-driven testing, is in the software coding stage, in accordance with the internal structural testing procedures of the program, through testing to detect whether the internal actions of the product are normally carried out in accordance with the design specifications, and each item in the program is inspected Whether the passage can work correctly according to the predetermined requirements. White box testing is an independent and critical stage in the software life cycle. It represents the final inspection of specifications, design, and coding, and is also an important means to ensure software quality. [0003] Coverage statistics are key indicator parameters for measuring test cases and codes in white box testing, including stat...

Problems solved by technology

Executable file implantation code has the following problems: different operating systems must use different executable files, for example, the executable file of Windows operating system is PE file (Portable Executable, portable executable body, is Windows operating system self Executable file format) is not applicable to other systems, such as UNIX operating system, XENIX operating system, LINUX operating system, it is necessary to make the corresponding executable file of the system; moreover, the file format of the executable file is complex, Difficult to analyze; code needs to be relocated after insertion, and relocation is difficult
