actually far behind. The second is the test of abnormal calls, such as the stability test under high load, testing of potential user Abnormal Input, testing of the module affected by local system faults, and testing of module stability when frequent abnormal requests block resources. Of course, not programmers need to perform such a complete test on each piece of code, but programmers must be aware of their position in the overall project and various performance requirements, conduct relevant t

Nine essential capabilities for success 1. Correct your mind and dare to face the realityFor those who constantly complain about the bad reality, the unsatisfactory reality is like the cage of life, which binds both hands and feet and the body and body, so they often succumb to the pressure of reality, become a weak man, and those who truly become a major event dare to challenge reality and refine their viability in reality. This is called a strong ma

Essential tools for C ++ programmers From the programmer's perspective, the use of good tools will always give people a multiplier effect. How can we choose between a wide range of tools and software. Not long ago, I posted a post on the C ++ forum of csdn, In order to solicit wide comments and receive a good response. On the basis of finishing the post, this article also makes some supplements. I would like to express my special thanks to the followi
