Software testing is an important means of software quality assurance, through software testing to find software defects, so as to modify defects, provide software quality level. In the field of software testing, there is no teaching flaw detection mechanism to fully detect all software defects.
Software defects and hardware defects are different, software defects in general, will not cause direct personal injury to users, so many people do not realize the severity of software defects and harm. However, for the use of software companies, departments, especially the High-tech areas of scientific research departments, and so on, software defects will cause significant losses in today's society, our life has been inseparable from a variety of software.
In order to solve the problems caused by software defects, people are still looking for ways to effectively find software defects, automated testing can partially address coverage and test efficiency, but manual testing is still the main way to find errors. However, it is not only by software testing to ensure that the software is not wrong, software testing is only a means of discovering software defects.
Because software testing is a kind of method to find software defect directly, it becomes the main means of software defect control. By studying the requirements of software products and the actual business scene of the users, the tester designs a variety of test cases and determines whether the tested system meets the needs of the users by executing the test cases. Although software testing is the most effective way to find defects so far, it can find most software defects in software development, but software testing alone can not guarantee the quality of software, especially in the time of software testing can not be fully guaranteed, at present, most of the domestic companies do not pay much attention to the premise of testing, Testers can only try to find as many software flaws as possible within the time allowed.
In addition to software testing, the software configuration management, schedule control and other project management means to ensure the smooth and orderly development of software research, combination of software requirements control, demand analysis, code review, design review and other forms to ensure the quality of software.
