In software testing, the meanings of front, middle and back are similar to those in software project development, except that they refer to different parts or levels in the software testing process.
In software testing, the foreground usually refers to the user interface, that is, the interactive interface presented to the user by the application under test. Foreground testing mainly focuses on the reliability of user operations, fluency of operations, and correctness of input and output data. For example, the foreground test will verify whether the user can perform various operations normally when using the application, such as clicking a button, entering a text box, using a drop-down menu, etc.; at the same time, it is also necessary to verify whether the application can respond and handle these operations correctly, Such as displaying options correctly, returning correct text results, etc. In the foreground test, the tester needs to simulate the actual user's operation behavior, and cover all possible scenarios and situations as much as possible, so as to ensure that the user interaction experience of the application meets expectations.
In software testing, the middle platform usually refers to the part of the background business logic processing and data management, which is the bridge connecting the foreground and the background. Middle-end testing mainly focuses on the correctness and stability of back-end business logic processing and data management. For example, in mid-stage testing, testers need to verify that the application can correctly process and store user-input data, such as updating the database correctly, generating correct reports, etc.; at the same time, it is also necessary to verify that the application can correctly perform various services Logic, such as correctly calculating the order price, judging user permissions, etc. In the mid-stage test, testers need to understand the implementation details of the business logic and data flow, ensure the stability and correctness of the mid-stage part, and check whether the data interaction between the front-end and back-end is normal.
In software testing, the background usually refers to the part that manages and monitors the application under test, including system settings, updates, backups, maintenance, etc. Background testing focuses on application security, reliability, and operability. For example, in background testing, testers need to verify that the application can correctly perform system settings and updates, such as correctly releasing new versions, fixing vulnerabilities, etc.; at the same time, it is also necessary to verify that the application can correctly record and process log information and handle exceptions situation etc. In background testing, testers need to understand the management and monitoring mechanism of the application, ensure the stability and high availability of the application, and check whether the background functions can operate normally.

To sum up, the foreground, middle stage, and background of software testing are responsible for different responsibilities and tasks, but they work together to complete the task of software testing. In the process of software testing, testers need to fully understand the relationship and role among the foreground, middle stage, and backstage, and adopt effective testing strategies and methods to ensure the quality and stability of the software system. In addition, the specific implementation methods of the foreground, middle stage, and backstage in software testing also vary according to different application scenarios and requirements.
For example, in the testing of web applications, the foreground test usually uses automated testing tools or manual testing to verify the operation behavior of the user interface; the mid-stage test requires automated testing of data management, business logic, etc., and can use some existing Advanced technology simulates back-end services to quickly locate problems; background testing requires the use of some system management tools or security testing tools to verify the reliability and security of applications.
In the testing of mobile applications, the foreground test needs to conduct manual testing and automated testing by testing mobile phones, simulators and other devices to verify the correctness and stability of the user interface; the middle platform test needs to use cloud services, simulators and other technologies for business Automated testing of logic and data management; background testing needs to verify the reliability and security of the mobile application system through some management tools and security testing tools.
In short, in software testing, the coordination of the foreground, middle and backstage is very important. Testers need to adopt effective testing strategies and methods according to different application scenarios and needs to ensure the quality and stability of the foreground, middle and backstage, and finally achieve high-quality software products.
