In addition to the growing complexity of software systems, test effort takes increasing amounts of time and correspondingly more money. Testing costs may be reduced without compromising on software quality by minimizing test sets through optimal selection of test cases and introducing more powerful test tools. Attaining high levels of test automation is the objective. There are problems which make the introduction of test automation in industry quite difficult. Solution providers and tool developers often do not understand the requirements in industry for test automation. Otherwise introducing test automation could become counterproductive. This paper points out essential demands on GUI test tools for industrial purpose.
