After all, all the users are people. All usability issues respond to the interaction and impact of human behavior with the site. When testing a different user base, you don't need a lot of testers (users) in each user base, and one of the following testers is enough: 1, if you test two user groups, each group needs 3-4

Attributes. We mainly use two methods to query XML documents, selectnodes (XPath expression) and selectSingleNode (XPath expression). SelectNodes returns a NodeList object, which means that all XML nodes that conform to XPath expressions will be returned, and you need to traverse the returned results. selectSingleNode returns only the first node that conforms to an XPath expression, or returns NULL. Here are a few examples: 1. Return all contact nodes: The code is as follows

area of software quality. Outdated code methods are so ambiguous and absurd that there are many errors in managing requirements analysis, design, and documentation, and there is not much important literature on quality subjects. Function Point method was in 1991 by the United States national quality departments and military systems, MIS projects and so on. The functional point method is also used to control or predict test cases or test runs for software projects in 1993. Reference bibliogra
