along with Website construction With the rapid development of, the Web has had a profound impact on business, industry, banking, finance, education, government and entertainment, as well as our work and life. Many traditional information and database systems are being transplanted to the Internet, e-commerce is growing rapidly, and even complex distributed applications are gradually emerging in the Web environment.
 
In the process of website construction, testing, validation and acceptance based on Web system is an important and challenging work. Web based system testing is different from traditional software testing. It not only needs to check and verify whether the system runs according to the design requirements, but also needs to test whether the display of the system in different users' browsers is appropriate; It is important to conduct security and usability tests from the perspective of the end user. However, the unpredictability of Internet and Web media makes it difficult to test Web based systems. Therefore, we must research new methods and technologies for testing and evaluating complex web-based systems. The release cycle of general software is calculated in months or years, while the release cycle of Web applications is calculated in days or even hours. Web testers must deal with shorter release cycles, and testers and test managers are also facing the transition from testing the traditional C/S structure and framework environment to testing rapidly changing Web applications. Next, we will discuss the problems that should be paid attention to in the current website testing from the aspects of function, performance, availability, client compatibility, security, etc.
    
(1) Link test. Linking is a major feature of Web application systems. It is a major means of switching between pages and guiding users to go to some unknown address pages. Link testing can be divided into three aspects. First, test whether all links actually link to the linked page as instructed. Second, test whether the linked page exists. Finally, ensure that there are no isolated pages on the Web application system. The so-called isolated page means that there is no link pointing to the plane, and only if you know the correct URL address can you access it. Link testing can be automated, and many tools can be used. The link test must be completed in the integration test phase, that is, after all pages of the entire Web application system have been developed.
 
(2) Form test. When users submit information to the Web application system administrator, they need to use form operations, such as user registration, login, information submission, etc. In this case, we must test the integrity of the submission operation to verify the correctness of the information submitted to the server. For example, whether the birth date and occupation filled in by the user are appropriate, whether the province filled in matches the city, etc. If the default value is used, the correctness of the default value should also be verified. If the form can only accept certain specified values, you should also test. For example, only certain characters can be accepted. These characters can be skipped during the test to see whether the system will report an error.
 
(3) Cookies test. When a user accesses an application system using cookies, the Web server will send information about the user and store the information in the form of cookies on the client computer, which can be used to create dynamic and customized pages or store login and other information. If the Web application system uses cookies, you must check whether the cookies work properly. The content of the test includes whether the cookies work, whether they are saved at the scheduled time, and what impact the refreshing has on the cookies.
 
(4) Design language test. The differences in the versions of Web design languages can cause serious problems on the client or server side, such as which version of HTML to use. When developing in a distributed environment, the developers are not together. This problem is particularly important. In addition to the HTML version, different script languages, such as Java, JavaScript, ActiveX, VBSctip, or Perl, also need to be verified.
 
(5) Database test. In Web application technology, database plays an important role. Database provides space for the management, operation, query of Web application system and the realization of user's request for data storage. In Web applications, the most commonly used database type is relational database. You can use SQL to process information. In a Web application system that uses a database, two types of errors may generally occur: data consistency errors and output errors. Data consistency errors are mainly caused by incorrect form information submitted by users, while output errors are mainly caused by network speed or programming problems. For these two cases, tests can be carried out separately.
