Software testing comes into being with software products，The early development scale was relatively small、The product is also relatively simple，So the meaning of testing is also very narrow，Developers call testing "debugging"，The purpose is to correct known errors in the software。In the domestic market，Many software companies focus on development、The phenomenon of light test，There are even many Internet and software companies do not have special testing positions，It requires development and internal testing by non professionals before the product goes online，This leads to frequent quality problems of software products，There are various problems after online。

In the past two years，With the rapid development of Internet，Software systems are becoming more and more complex，A software product is no longer written by 1-2 developers alone，It's about teamwork，Maybe everyone is only responsible for a single module，There is no overall understanding of the product，So these software are very easy to make mistakes at runtime，The industry calls this a bug。

And every software engineer has a dead corner of thinking，It's not easy to find the mistakes you write，So at this time, we need a special software testing engineer to check the product in a professional way。

With the gradual improvement of user requirements for products，Testers will only be more and more important in the enterprise，Beijing, Shanghai, Guangzhou, Shenzhen and other first tier cities will drive other cities to develop together。therefore，The future of software testing will only be better and better，of course，The most basic functional testing job requirements have been very few，But automation、performance、Security and even big data testing that may appear in the future、There are still many opportunities for AI testing。
