Understanding the meaning and scope of software testing

Software Quality has always been the focus of software engineering, it has become a field that people have been researching and exploring for decades. To improve software quality, people not only obtain effective methods and best practices from different aspects such as corporate culture, software process model, demand engineering, and design model, in addition, we began to focus on software testing, and put more considerations and investment in software testing. Although the quality is built in, software testing still plays a very important role. the software test itself is changing. It is no longer just a guard-it is tested before the software is released, but it is becoming a continuous feedback mechanism, through the entire process of software development , you can discover problems as early as possible, reduce development costs, and improve software development productivity. the software tester is no longer an aid in software development, but one of the subjects and active participants of the software development team. on the first day of the project, the tester will participate in the discussion, review, and other activities of the project requirements and design, and discover software requirements and design implementation problems as soon as possible, promptly discover quality risks in software projects. The software development team must control future quality risks as much as possible before delivering the product, which must depend on effective software testing. Extend the narrow concept of the traditional Program test to the software testing concept gradually recognized by the industry today, the test covers activities such as requirement verification (review) and design verification (review. Software testing runs through the entire software life cycle. From the beginning of Requirement Review and design review, software testing is involved in the development activities of software products or the implementation of software projects, and other development teams collaborate and complement each other, constitute an organic whole in the software life cycle .

Software testing is not a simple task,It is far more complex than people can imagine.Testing a software system efficiently and with high quality involves many factors and various problems, in addition, the best balance between test efficiency and test risks and effective test strategies need to be overcome by testers one by one. Do a good job in software testing,It is not only necessary to think about problems from the customer's perspective, to truly understand the customer's needs, to have good analytical and creative thinking abilities, to complete functional testing and user interface testing, it can understand the implementation mechanism and various application scenarios of software systems, and has a solid technical skills, perform more challenging tasks such as performance testing, security testing, compatibility testing, and reliability testing with test tools. The main purpose of software testing is to discover defects in the software, adhere to the "quality first" principle, and encounter some resistance in actual operations, which must be overcome by testers.From these perspectives, to become a good test engineer, it is actually more demanding than the design and programming personnel, not only to reflect superb technical capabilities, such as system platform settings, architecture design analysis, programming, and other capabilities, as well as your own business analysis capabilities, understanding of customer needs, and team communication and collaboration capabilities.
