In recent years, with the rapid development of emerging technologies such as cloud computing and big data, we are increasingly using various tools to store, process, analyze and present massive amounts of data. These data include both structured data (such as tables in databases) and unstructured data (such as images, text, audio, video).
The traditional manual testing process has been unable to cope with the rapidly growing demands of new business scenarios. In order to improve R&D efficiency, reduce testing costs, and shorten testing cycles, many companies and organizations have adopted automated testing methods, such as unit testing, integration testing, system testing, and interface testing. The basic principle of automated testing is to repeatedly run test cases, detect whether there are potential errors or exceptions, and report the test results. However, with the development of the Internet, the popularity of the mobile Internet, and the increasing complexity of application scenarios, how to apply automated testing to business systems still faces many difficulties. One of the important factors is the automated and intelligent testing of metadata.
Metadata is data that describes a resource, such as file attributes, email messages, images, when and where a video was taken, author of the document, date created, date last modified, subject terms, keywords, abstract, etc. Automated testing of metadata allows developers to better understand the content and characteristics of resources, which can help identify and fix errors or anomalies. In addition, metadata intelligent testing can also help business personnel better manage the resource library, discover, classify and organize information that is closely related to value.
Therefore, automated and intelligent test metadata is of great value. Only through automated and intelligent testing of metadata can we truly be "user-centric" and better meet user needs. In this context, I think that "Automated and Intelligent Testing of Metadata" should be taken as an important technical direction to discuss the latest progress in automated testing and the theoretical basis, algorithms, practices, challenges, etc. of metadata testing.
2. Explanation of basic concepts and terms
First, we need to understand what metadata is. Metadata is the data used to describe the data. It consists of an optional set of key-value pairs that describe the data of a resource, such as an image's
