What basis do you need to learn software testing engineers?

First of all, we should master the basic theory of software testing, and it is best to understand the basic operation of database and a scripting language. In fact, the basic theory of software testing is relatively simple, and now there are a lot of data. The basic operations of a database are generally adding, deleting, modifying, checking, backing up and restoring.

Software testing can be roughly divided into black-box testing, white-box testing and black-box testing. Black-box testing focuses on external structure programs, regardless of internal logic structure, mainly for software interface and software function testing. Black-box testing generally does not need software development foundation.

It is easy to master the basic theory of software testing and pay more attention to the accumulation of experience. Many friends who are not computer-related majors are mainly functional tests.

Extended data:

Another classification method of software testing is functional testing and performance testing. Functional testing is basically a black-box test, while performance testing needs to involve the positioning and optimization of system bottlenecks. Usually need to master database knowledge, preferably a scripting language, such as JAVA or C.

The program is written by people, and mistakes are inevitable, but it is also because the program is written by programmers, who have a general concept of the underlying logic and possible problems.

The test engineer's job is to tell him the ID of the problem data, the scene where the problem occurred, what the test data looked like at that time, and so on. Instead of throwing a screenshot to the programmer and saying, "There is a problem here."

It seems that many test engineers like to learn Python, which is really a very friendly language for code beginners. However, for test engineers,

Test engineers face "bugs" in programs every day, and programmers create code every day. At least as a creator of junk code, I hate making mistakes. So in my opinion, it is very difficult to keep calm in the exam, because I don't know when I will make a strange mistake.

White-box testing needs to develop a foundation because the code involves traversal. At present, there are far fewer white-box testers in China than black-box testers, and many software development engineers have turned to soft boxes.
