Abstract: The existing Web testing technologies mostly start from the front end, by analyzing the page DOM structure to obtain the state and the state jump condition. But all the technologies treat any DOM node changes as a new formation DOM, if any operation that leads to the change of DOM is considered as a new operation and regenerates test cases, this is a waste of time and human force. In this paper, a Web application unit test method that is based on page DOM similarity is proposed. First it uses a crawl to get the page state and the corresponding DOM structure then uses Dom similarity to evaluate and classifies the DOM, finally uses the center of the cluster as corresponding operation’s result, and returns to the application to find the code block for testing. The experimental result shows that this method can effectively reduce the redundant state jumping in “single DOM to single state” mode, and it can achieve reasonable function discovery rate, effectively reduces the redundancies of the test state.
