What methods do you use to test scalability in web applications?

Question

Our testing system is rather rudimentary; launch the browser, see if it works. Recently, we encountered problems discovered by our client with our application, where the number of users created a slowdown in the application. The application is basically a huge Word document in which people simultaneously edit their own versions. Part of the problem came from a lack of knowledge of how to test multiple instances at the same time. My partner and I thought about how to test this; one idea was to hire an internet cafe and hire students for an hour to crack the application.

In what other ways did people try to imitate concurrency while testing their web application? Most of the recommendations here are for a specific methodology; I ask, how do you test it to make sure it works?

Answer 1

If you have never tested Selenium , you need to do this. This will allow you to perform automated web testing through a browser. So, the first problem is solved.
