Citrix DaaS, Virtual Apps and Desktops, Microsoft RDS and cloud VDI still deliver pixels, not pages. A Workspace URL or RD Web Access test is the front door. The farm is the session host, and the number that matters is whether the chart appeared on the glass under concurrent load. CitraTest VU® drives the real client with keyboard and mouse, compares the live screen to baseline images, and measures that time with no agents on the session hosts.
Size the host from the glass, not the broker.
Key Features
Test real user experience:
Generate mouse activity and keyboard strokes –just like a real user–, and then test, measure and validate application response time, at the client UI, under various controllable load levels.
Non-intrusive load testing:
Rapidly test new applications without any code changes or production impact.
Ease of use:
Easily replicate and test all user actions (clicking, typing, comparing, verifying, awaiting …) via an intuitive point-and-click scripting wizard. You will be up and running in minutes, no scripting skills required,
Realistic and accurate testing.
Each CitraTest VU® test script executes in its own "desktop" and opens its own client connection to the server-under-test, just as a group of real users would.
See what the user sees.
CitraTest VU® automatically compares what it “sees” on the screen to baseline response images, and measures and reports response times at the client GUI. Immediately identify underperforming components with Tevron’s proprietary intelligent image recognition capabilities.
Record server performance under load
(Citrix Virtual Apps and Desktops, Citrix DaaS, Microsoft RDS, AVD and cloud session hosts) while the run is in progress. Use it for sessions-per-host, SKU choice and autoscale decisions — density with autoscale off, scale-out lag in a second run.
Flexible Testing.
Validate multi-step business days (logon, published app, open record, save), including Epic and other EHR on the glass. Separate a login storm from a sustain. You set ramp and concurrency.
Maximize ROI with just one license:
One license covers Citrix Virtual Apps and Desktops, Citrix DaaS, Microsoft RDS, AVD and Windows 365. HDX and RDP are still pixels. Test them that way.
2026 load-testing method
Rely on CitraTest VU® to:
Roll-out new applications and technology with confidence.
Mitigate risks associated with new technology deployment (virtualization, datacenter consolidation, application updates…).
Ensure production readiness, optimal performance and reliability
