Test Java Swing applications reliably in the browser with Webswing and QF‑Test. Automate your legacy GUI app without rewriting a line of code.
Testing Java Swing applications has always been difficult. Webswing changes that. Combined with native Webswing Test Tool or 3rd party QF‑Test, you can finally run clean, stable, browser-based UI tests without rewriting your app.
Testing Java apps has been a pain for years
If your team has ever tried to write automated tests for a Swing GUI, you know the struggle.It’s fragile. It’s tedious. You end up dealing with screen coordinates, inconsistent test machines, and flakey results. Installing the right JRE on every workstation becomes a full-time job. And just when you think your tests are stable, the environment breaks them again.
For most teams, this has meant giving up on automated testing altogether - or accepting it as a painful, unreliable process. But it doesn’t have to be this way anymore.
Webswing makes Java Apps testable in the browser
Webswing lets you run your existing Swing app in a modern browser with no code changes. But more importantly for testers, it gives your UI a clean, inspectable interface that automation tools can interact with.
You can simulate user input, access the component hierarchy, and even run your tests headlessly inside CI pipelines. No screen scraping. No fragile hacks. No “click-at-this-pixel” scripts.
It works the way testing should have always worked.
Integrate Seamlessly with QF‑Test
Pair Webswing with QF‑Test - a powerful and proven Java GUI testing tool - and you get the best of both worlds.
QF‑Test is already widely used for testing Swing, JavaFX SWT, and Netbeans applications. With Webswing, it simply connects to a browser session instead of a local desktop app.
You can inspect components, record and replay user interactions, create robust test scripts, and run everything across platforms - without setting up a local Java environment for each test machine.
It’s stable. It’s scalable. And it finally makes Swing automation feel modern.

A Simple Shift with a Huge Payoff
Moving your Swing app into the browser with Webswing doesn’t just improve user experience, it completely changes your testing capabilities.
You stop
- worrying about which JRE version is on which computer.
- writing brittle tests that break when you move from Windows to Linux
- treating testing as a side project
Instead, your GUI becomes testable like any web app - repeatable, inspectable, automatable.
This means better test coverage, faster feedback loops, and fewer bugs in production - without ever touching your application’s source code.
Modern Testing Without a Rewrite
There’s no need to migrate to a web framework just to make your GUI testable.
Webswing lets you keep your application logic as-is, while QF‑Test gives your testers the tooling they’ve always needed.
Together, they bring real automation to real-world Java GUIs - finally.
