What is software testing?

Software testing is an important means of software quality assurance. Software defects are discovered through software testing to modify defects and provide software quality levels. In the field of software testing, there is no teaching defect detection mechanism that can completely discover all the defects of the software.

Software defects and hardware defects are different. Under normal circumstances, software defects will not directly affect the user. Injury, so many people are not aware of the seriousness and harmfulness of software defects. However, for companies and agencies that use software, especially in some high-tech fields, software defects can cause significant losses. In today's society, our lives are inseparable from a variety of software. .

In order to solve the problems caused by software defects, people are still constantly looking for ways to effectively discover software defects. Automated testing can partially solve the problem of coverage and test efficiency, but manual testing is still the main problem of finding errors. the way. However, software testing alone cannot guarantee software errors. Software testing is just a means of discovering software defects.

Because of software testing, a means of directly discovering software defects is the main means of software defect control. By studying the requirements of the software products and the actual business scenarios of the users, the testers design various test cases and determine whether the tested system meets the user requirements by executing the test cases. Although software testing is the most effective means to find defects so far, it can find most of the software defects in the software development process, but software testing alone can not guarantee the quality of the software, especially when the software testing time is not fully guaranteed. At present, most domestic companies do not pay much attention to testing, testers can only find as many software defects as possible within the time allowed.

In addition to software testing, project management tools such as software configuration management and schedule control should be used to ensure smooth and orderly development of software development, combined with software demand control, demand analysis, code review, design review, etc. Forms to ensure the quality of the software.
