[rifat28dddd]

During tests, the system's characteristics are checked under high load: server response time, throughput, memory usage and other resource usage.

What is stress testing? In this case, they check how the application behaves under loads that go far beyond the norm.

If we take the same example with a site that will be visited by 10 thousand people per day, during stress testing they will simulate a load of 100 thousand users.

Load testing helps:

understand how the product behaves under the expected workload;
