System testing is the last procedur

System testing is the last procedure of software design and a very important step. It is used to check whether the quality, performance, security, etc. of the software can meet the needs of passengers. A set of testing procedures that meet the requirements will greatly improve the quality, credibility, and reliability of the software, reduce the error rate of the software, and reduce the risk factor of passengers. Usually system testing includes: functional testing, security testing, usability testing, performance testing, etc.In order to make the software run more stable, I conducted a comprehensive test, which is divided into two parts, one is the interface test; the other is the functional test.First of all, let's talk about interface testing. Interface testing is to enable the program to run the interface on different operating platforms and maintain the original style. After the test program runs normally, the font and picture settings on the running interface can be maintained very well. There are no font distortions!
