What is ui performance testing tools open source and do we need it in 2021? Yes, we do. You can’t force users to go through your website quickly if your website runs slow. If you have a shopping website where users want to complete a purchase, running a slow website will cause them to leave your website. This leads to loss of potential business.

StresStimulus targets application scenarios with other methods that are difficult to assess. Thanks to its autocorrelation, it automatically fixes replay errors. StresStimulus tracks and re-plays consumer behavior to reproduce patterns of variable use. It also tracks the load effect on the response and server architecture of the application. The result analyzer detects occult opponent defects that have not been seen by practical checks.
- The End-to-End Research Wizard encompasses all measures from recording to web application performance testing.
- On-site or cloud testing with many load generators supported.
- Function as an autonomous platform or add-on for Fiddler
- Export script to the test format Visual Studio to support scenarios that fail when documented directly in Visual Studio
- Manual scripting is not mandatory but available; it supports three languages scripting.
With the SmartBear LoadNinja, we can build advanced load tests without scripts easily, minimize test time by 50%, substitute load emulators with actual browsers, and gain actionable
browser-based metrics, all of them at a ninja pace. We can conveniently record customer-side conversations, debug in real-time, and quickly detect performance issues. LoadNinja allows teams with complex similarity, script translation, and script scrubbing to expand their test scope without losing efficiency.

Web performance is key for any application. It doesn’t matter if it is an eCommerce site, a helpdesk software, or even an online game, all of these are being used by real users who have real internet connections. Making sure that your page loads fast will greatly improve the user experience over slow connections. This is why it is so important to make sure you are using the right tools to do web performance testing. If you aren’t familiar with web performance testing there are plenty of other guides on this website.
