Problems solved by technology

However, in the process of searching the SFG graph by DFS, it is often easy to fall into repeated searches for the same sub-path, and the generated set of test cases for web applications is generally large, resulting in high cost and low test efficiency for web applications

Embodiment

[0041] In this embodiment, a depth-first dynamic search technique is used to generate a user interface state flow graph (SFG) as a Web application test model, and a test case is generated by reversely traversing the SFG graph. A complete path in the SFG graph corresponds to a test case of the Web application. The implementation steps are as follows:

[0042] 1. Generate SFG diagram

[0043] 1) Initially load the entry address of the web application to generate the initial state index of SFG;

[0044] 2) Analyze the DOM elements related to the clickable event in the index object, and extract the clickable event set {e 1 ,e 5}, select one of the unclicked events e 1 , simulating its triggering, generating a new state s 1 , update the SFG graph;

[0045] 3) Use the depth-first strategy to dynamically search for new states, update the SFG graph, and backtrack until there are no clickable events in the current state. as from s 1 Departure choose e 2 Simulate trigger, genera...

Abstract

The invention discloses a web application test case generation method based on a user interface state flow graph. The method includes: using the dynamic searching technology to generate the user interface state flow graph (SFG) to serve as a Web application test model, and performing reverse depth-first traversal on the SFG starting from a final-state node to obtain event sequence on a complete path from an initial-state node to the final-state node so as to generate Web application test cases, wherein visiting nodes are marked during the reverse traversal of the SFG, and the shortest paths from the initial nodes to the marked nodes are used to replace depth traversal during subsequent test case generation. By the method, test case set scale can be reduced under the premise that SFG edge coverage is guaranteed, Web application testing cost is lowered, and Web application testing efficiency is increased.

Description

technical field [0001] The invention belongs to the field of software analysis and testing in software engineering, and in particular relates to a method for generating Web application test cases based on user interface state flow diagrams.
