Abstract

The invention discloses a test case generation method and a test case generation device. The method comprises the steps of using steps in a flow of a software system as nodes of a directed graph, anddetermining numbers of the nodes; determining a sequence of the nodes according to an execution sequence of the steps, and determining marks for directed edges between the nodes; traversing the directed graph via a graph depth traversal algorithm, and using the numbers and the marks to record a node sequence of each path along a longitudinal direction of the directed graph and an edge sequence corresponding to the node sequence to generate a test case. According to the method, the flow in the software system is completely represented by the node sequence and the edge sequence; for software with various functions and many turn test points, breadth, depth, coverage and accuracy of the test case are ensured, the test case can also be quickly and conveniently generated and compiled, and time and cost are saved. Correspondingly, the test case generation device disclosed by the invention also has the abovementioned technical effects.

Description

technical field [0001] The invention relates to the technical field of software testing, and more specifically, to a method and device for generating test cases. Background technique [0002] With the development of information industries such as computer technology and Internet technology, there are more and more software development projects. Developers adopt the agile development model to speed up the development iteration cycle. However, with the continuous acceleration of the software development iteration cycle, testers Bringing a huge workload and challenges. [0003] Before performing software testing, testers need to write and generate test cases for the required functions of the software, and operate the program under the guidance of the test cases to find program errors, measure software quality, and evaluate whether it can meet the design requirements. At present, the writing and generation methods of test cases in use mainly include: equivalence class division,...
