There may be several reasons why Meituan's new store did not conduct stress tests. First of all, it may be because the traffic forecast of Meituan's new store is not high and it does not meet the standard of stress test. Secondly, Meituan's new store may have been fully tested in the early stage and had sufficient quality assurance before going online, so it can ensure normal operation without stress testing. Finally, Meituan's new store may have used some high-performance technologies or architectures, which can withstand high traffic without stress testing.

It should be noted that stress testing is a method to test the system load, which evaluates the performance and stability of the system under high concurrency by simulating a large-flow system. Although the new store of Meituan did not carry out stress test, it still needs to carry out various tests before going online, including functional test, performance test and safety test to ensure the normal operation of the system and user experience. At the same time, in practical applications, stress testing is also very important, especially for some large websites and applications, which need to be fully tested to ensure their high concurrency stability and reliability.
