People often ask if they can use Selenium for load testing. The Selenium website says: Performance testing using Selenium and WebDriver is generally not advised. Not because it is incapable, but because it is not optimised for the job and you are unlikely to get good results. The site goes on to recommend JMeter. We would say that Selenium can be used for load testing with limitations as many RedLine13 customers do. RedLine13 is a cloud-basedRead More →

Speak the Lingo using Load Testing Terms

Load testing is a niche skill within the large trade of quality assurance. With any trade, being able to communicate effectively the nuances and concepts used is essential.

JMeter Custom Thread Groups

With any JMeter test, thread groups constitute the basic container for test plan requests and other elements. The simplicity of the basic thread group is such that with enough ingenuity anything is possible. Through clever use of scripting, timing, and logic elements it is possible to simulate any user behavior. However, for simulating complex traffic patterns there is an easier way. One of the most useful plugins for JMeter comes as the “Custom Thread Groups” collection.Read More →
