4 types of Web functional testing

1. Page Link Test

A link to a page is an important way to navigate from one page to another, and when you do a page link test, you need to verify two questions:

· If the page does not exist, as the page cannot display information, the page link is considered invalid. There are many factors that cause the page invalid, mainly have the page file does not exist, the link address is not correct, etc.

· Whether the page jumps to the specified page, mainly to verify the correctness of the page, this test should also be considered in the Web functional testing section.

2. Design language test

The design language here mainly refers to the HTML language and different scripting languages, in some cases, the HTML language with the customer browser may have different effects, so this is a test to consider the factors. As in Netscape 4 7, the form content cannot be qualified as a read-only attribute, so that when the contents of the form need to be disabled or restricted, the program must consider other ways, such as using JavaScript scripts for processing.

3. Web Graphics Testing

Web graphics are a common means of displaying information, such as GIF images. Many times, the graph is mixed with the text to use, therefore, in the Web graphics test, not only to confirm that the text is correct, but also need to confirm the content and display of the picture, such as whether the text is correctly wrapped around the picture, the text of the picture prompt is correct, the picture points to the link is correct and so on. Of course, the page load test, the picture display is also an important factor, sometimes, when the network status is not good and the picture file is larger, you may encounter the link timeout error, these also need to be considered within the graphics test. Graphic testing also hemp when considering display problems, such as whether the graphics display at different resolutions is correct, whether the graphics supported by the browser add-in can be loaded correctly, etc.

4. Form Testing

从设计的角度来看，表单是在访问者和服务器之间建立了一个对话，允许使用文本框、单选按钮和选择菜单来获取信息，商不是用文本、图片来发送信息。通常情况下．要处理从站点访问者发来的响应(即表单结果)，需要使用某种运行在Web服务器端的脚本(如PHP、ISP)，同时在提交访问者输入表单的信息之前也可能需要用浏览器运行在客户端的脚本(通常是使用JavaScript)。在进行表单测试的时候，需要保证应用程序能正确处理这些表单信息，并且后台的程序能够正确解释和使用这些信息。举个例子．用户可以通过表单提交来实现联机注册。当注册完毕以后，应该从Web服务器上返回注册成功的消息。
