Performance testing, load testing, stress testing What's the difference? Performance testing (or antisymmetric user concurrency performance testing), load testing, strength testing, and capacity testing are some of the areas of performance testing, but concepts can easily be confused. Here are a few concepts to introduce.
Performance test (performance

Depending on the time and resource characteristics of the product, the efficiency test can include different types of tests, such as performance tests (performance test), load tests (loading test), and stress tests (Stress test). These three types of efficiency t

IntroducedWhen any software development project is nearing completion, it may have passed numerous tests, especially in the context of testing and development of simultaneous agile testing. No matter how many rounds of testing you have, once your application is nearing completion, there is only one way to know if your software can meet the real needs of the real user base, which is the load test. You can us
There is nothing worse than this, the adoption of a new application, and its performance is so bad, leading to business in a scream of pause. This is not a new phenomenon; it is the fact that I have often encountered such a fact. I bet you've been there before. So how do you prevent these performance problems and what are the solutions?
In cases where these applications are "paused in the Scream", the application is usually already properly tested in the short testing time of the functional all
