Title:
ANALYSIS FUNCTION ADDITION DEVICE, ANALYSIS FUNCTION ADDITION METHOD, AND ANALYSIS FUNCTION ADDITION PROGRAM
Document Type and Number:
WIPO Patent Application WO/2024/079804
Kind Code:
A1
Abstract:
An analysis function addition device (10) comprises a virtual machine analysis unit (121) that analyzes the VM of a script engine, an instruction set architecture analysis unit (122) that analyzes an instruction set architecture, which is a system of instructions of the VM, to collect VM instructions and determine the content of the collected VM instructions, and a calculation unit (123) that uses the architecture information acquired by the virtual machine analysis unit (121) and the instruction set architecture analysis unit (122) to construct a first control flow graph representing an entire path executed exhaustively through multipath execution, and a second control flow graph representing paths executed during execution of a test subject, and uses the first control flow graph and the second control flow graph to calculate a code coverage of a script executed on the script engine.
