Tevron’s load testing product for end-user computing—Citrix, Microsoft RDS, and cloud-hosted virtual apps and desktops.
Direct answer: CitraTest VU® is software from Tevron that load tests virtual apps and desktops from the real user GUI (on-the-glass) using image recognition. It generates concurrent virtual users against Citrix Virtual Apps and Desktops / DaaS, Microsoft RDS / RemoteApp, and cloud session hosts, measures end-to-end response time as the user sees it, and does not install agents on your production servers.
Who it is for
- EUC / VDI architects sizing Citrix or RDS farms
- Performance teams proving logon storm and density before go-live
- Ops validating image, GPO, profile, or cloud catalog changes
Platforms
- Citrix Virtual Apps and Desktops, Citrix DaaS / HDX
- Microsoft Remote Desktop Services, RemoteApp, RDP
- Cloud-hosted session catalogs (for example AVD-style multi-user)
How it works (short)
Scripts drive the actual client path. Playback compares the screen to baseline images and times when the desktop or published app is ready. Load generators sit outside production. Server metrics can be collected alongside UX timings. See the methodology and full product page.
CitraTest VU vs CitraTest APM
| CitraTest VU | CitraTest APM |
|---|
| Job | Load / capacity / change validation | Ongoing synthetic monitoring |
| When | Before and during major changes | Production, continuously |
| Shared idea | On-the-glass real user experience, not protocol-only |
APM product: CitraTest APM.
Vs common alternatives (honest frame)
- Generic web load tools — fine for HTTP portals; weak for HDX/RDP session UX
- Protocol-only Citrix/RDP scripts — useful infra signal; can miss slow on-screen apps
- CitraTest VU — built for EUC sessions measured from the glass under concurrency
