specific example

[0070] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the application examples of the solutions of the present invention will be described below, obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments . All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of the present invention shall fall within the protection scope of the present invention.

[0071] The code coverage evaluation method of the present invention can obtain the binary code coverage information of the test case set for testing the executable program. Systems developed through this program can automate the process of evaluating binary code coverage. The system imports the executable program for static analysis, and then imports the test case set. After the test case set is executed in the system, the corresponding binary code coverage evaluat...

Abstract

The invention provides an automated evaluation method for binary code coverage of a testing case set for an executable program. The automated evaluation method includes step 1, executing static analysis on the executable program with a binary code expression form, converting the binary code expression form into an assembly instruction expression form through disassembly during static analysis, and performing basic block division on the executable program with the assembly instruction expression form; step 2, utilizing a testing case to execute dynamic analysis on program process, executing instrumentation processing during dynamic analysis to capture executing track, executing filtering operation during instrumentation processing for basic block filtering to remove an external instruction of the executable program; step 3, utilizing a virtual memory address of the executable program to evaluate binary code coverage of the testing case set by matching static analysis result of the step 1 and dynamic analysis result of the step 2.

Description

technical field [0001] The invention relates to the computer field, and more specifically, the invention relates to an automatic evaluation method for binary code coverage of a test case set of an executable program. Background technique [0002] Code coverage is the number of process states that a test program can achieve or execute through test cases generated manually or by tools. This is an important concept that researchers conduct pioneering research in the field of testing. Code coverage is a measure used to describe the degree to which a program is tested through test cases. It is one of the bases that software developers and testers often use to decide whether the test for the application is sufficient, and it is also an important indicator for evaluating the quality of the test. [0003] Executable programs refer to files that are loaded into memory to perform specified tasks. Executable programs are composed of binary codes, including basic information of files ...
