xtst

xtst, usually rendered as Xtst, refers to the X Toolkit Intrinsics test suite associated with the X Window System. It comprises automated tests designed to verify the behavior and conformance of the Xt library and its widget family, focusing on areas such as event handling, resource processing, geometry management, and the life cycle of Xt-based widgets. The tests are written to exercise common scenarios encountered in Xt applications and to help detect regressions during development and porting.

The scope of xtst is largely centered on the Xt toolkit, which provides the underlying infrastructure for building user interfaces in X11 applications. Test cases commonly involve creating Xt applications, instantiating widgets, manipulating properties, dispatching events, and observing resulting state changes or error conditions. By validating that widgets respond predictably to events and adhere to resource specifications, xtst aids developers in ensuring toolkit reliability across platforms and configurations.

Origins and usage context vary across X.Org and older X11 distributions. xtst has appeared as part of broader X Toolkit testing efforts and may be included in historical or legacy Xt-based development environments. In modern practice, some projects rely on newer testing frameworks, but xtst can still be found in older releases or repositories focused on Xt compatibility.

Running xtst typically requires an environment capable of rendering X11 windows, or a headless setup with a virtual display. Tests are executed within a build or test harness, often alongside other toolkit tests, and report pass/fail results with diagnostic output to aid debugging.
