Testing the scalability of a web application is essential to ensure that it can handle increased traffic. You can use several methods to test the scalability of a web application.
One method is to test the application under load. That involves simulating a large number of users accessing the website at the same time.
Another method is to test the application's capacity. That involves testing how much data the application can handle before overloading.
Finally, you can also test the response time of the application.
