Final answer:
The question refers to the process of checking web pages and their code for errors before they are published, which is known as code validation or quality assurance testing. This process ensures compatibility across different browsers, adherence to coding standards, and identification of security vulnerabilities.
Step-by-step explanation:
Before modified or new pages are published, pages should be processed by a code validation routine to ensure that all the code, including applets, works. This is known as code validation or quality assurance testing.
Code validation is an essential step in web development that involves checking the syntactical correctness of the code against formal standards or specifications. It is crucial to identify and correct any errors or issues to ensure that the web page functions correctly across different web browsers and platforms. For example, validating HTML code against the World Wide Web Consortium (W3C) standards can help detect missing closing tags, improperly nested elements, or invalid attributes that could lead to unexpected behaviors when the page is viewed.
Similarly, when it comes to applets or any scripts incorporated in web pages, proper validation ensures that the code executes correctly and does not contain security vulnerabilities. Moreover, employing automated quality assurance tools can help streamline the validation process, reduce human error, and save time. It is important to carry out this process in the development phase as part of a comprehensive testing strategy to facilitate optimal functionality and user experience before the web content goes live.
