Squish for Qt applications

With Squish for Qt you can automate the tests of your application on any desktop, mobile and embedded system without the need to modify the application. This allows for the creation of functional regression tests and system tests for Qt Widgets, Qt Quick and QML applications and even to automate interactions with embedded web content (Qt Webkit or Qt WebEngine).

Taking cross-platform support seriously, a test created on one platform can be run against the same Qt application on any other platform with no changes required. With Squish, you can also be sure to be the first to get support for all new Qt versions and features.

Squish for other applications

The beauty of Squish is that it is compatible with a wide range of browsers, operating systems, and platforms.

Beyond Qt applications, it can also be used to automate native Windows, Java, Web and HTML5, Android and iOS, macOS, and Tk applications. It also supports all applications running on desktop, mobile, or embedded devices capable of running a VNC server.

Squish Understands Qt the Way Qt Developers Do

For teams already committed to Qt, Squish is a natural extension of the Qt ecosystem.

As one user summarized the experience:

“Squish is the best GUI testing tool I’ve worked with. Its runtime performance is great and it has a low barrier to get up and running. It feels much more lightweight and flexible than any other tool I’ve used.”
— Joshua Niehus, SQA Engineer for UI Automation, Bio-Rad Laboratories

In practice, Squish helps Qt teams move from reactive GUI testing to a scalable, maintainable approach, one that keeps pace as applications grow in complexity and reach.
