Case Study: Komatsu achieves 100% GUI test coverage and 21.4% fewer man-hours with Qt Group’s Squish

Komatsu cuts GUI testing man-hours by 21.4% with Qt Group

Komatsu Ltd., a global construction and mining equipment manufacturer, faced a significant challenge in manually testing the GUI of the ICT monitors installed in its machinery. This process was time-consuming and offered very limited test coverage. To address this, Komatsu adopted the Qt Group's Squish test automation tool to streamline its testing process.

By implementing Squish, Komatsu automated its GUI testing, which seamlessly integrated with its existing Qt-based development environment. The solution from Qt Group reduced testing man-hours by 21.4%, cutting the effort required by 2.4 man-months. Furthermore, test coverage was dramatically increased from approximately 1% to 100% across all testing levels, while also enabling efficient multilingual testing for its equipment sold worldwide.
