functional and load testing real browsers

Real browsers


A real browser is used for each and every virtual user when executing testing. The browser is controlled by the virtual user which keeps it 100% accurate.

Record real user journeys


A Virtual User (VU) simulates user actions enabling you to record real user journeys. Extensive scripting support means virtual users can be asked to replicate all aspects of user interaction under differing conditions.

load testing reusable scripts

Re-usable scripts

Scripts stay usable. No need to re-record full scripts, only update elements that correspond with changes made to your site design, not the backend.

No correlation


The real browser handles correlation, identifying dynamic values within URLs, headers, cookies and local storage, with no errors.

Customer Testimonial

“We are always looking to improve application performance.”

“The advice from JAR Technologies was insightful and the deployment of JAR:TestLab was easy. This enabled us to accurately assess the application, complete load testing and get detailed results to inform decisions.

This meant we could quickly respond to our clients with assurance on the true performance of their websites and help them to successfully execute their projects.”
