Embodiment Construction

[0064] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0065] 1. Path coverage generation technology

[0066] The core of path coverage is to find the most errors in the program with the least test cases. The minimum set of test cases should be able to cover all paths in the program. In order to achieve path coverage, the number of paths of the program under test must be known exactly, in order to arrange test plans, allocate test resources, and evaluate the coverage achieved by the actual test to decide whether to end the test work. Path coverage is the only coverage testing method that considers the compositional relationship between different decisions in the same program, and it requires that each possible path in the program be executed at least once. Path coverage has strict coverage rules and thorou...

Abstract

The embodiment of the invention provides a Python-oriented function calling path generation method and system. The method includes: acquiring an abstract syntax tree (AST) of Python source code, and traversing the abstract syntax tree to acquire key information therein; and combining control structure characteristics of a Python language to construct a corresponding function calling relationship model according to the extracted key information, carrying out storage by a tree-shaped structure, and recording calling relationships between functions to generate the function calling relationship model, wherein each node in the function calling relationship model represents one of the functions in the source code, and a child node of one of the nodes represents a branch if the child node exists,one of the nodes represents the function, which is executed in an orderly manner, if a branch of the node does not exist, and sibling nodes and parent nodes in the function calling relationship modelare in parallel relationships, and indicate multi-branch structures in the source code.

Description

technical field [0001] The invention relates to the technical field of computer software, in particular to a method and system for generating a Python-oriented function calling path. Background technique [0002] With the rise of Python, more and more programmers and researchers choose Python as the language of choice for web applications, game development, and scientific computing. In the era of rapid development of Internet technology and big data technology, Python, as an object-oriented interpreted computer programming scripting language, is known for its good readability, interactivity, versatility, portability, scalability, Features such as maintainability and embeddability have attracted many software developers and become a leader among many scripting languages. In recent years, Python has become one of the most popular programming languages, gradually becoming the language of choice for scientific computing, web application and game development. Therefore, the tes...
