(This is an advanced course that makes testing more practical. The course is aimed at engineers who want to improve their testing skills, and students who want to try their hand at testing. The course content is a practical tutorial of advanced testing techniques. There are no introductory courses for students with zero foundation. Students need to have the best basic knowledge of the test to be better suited to study. The course content includes interface testing, mobile terminal testing, Postman interface testing, JMeter interface testing, Fiddler packet capture case courses, etc. These are more practical courses than before.)
