Low-cost Graphical User Interface Regression Test Framework

Graphical User Interface(GUI) is created with rapid prototyping,has characteristics that differ it from traditional software,so test techniques for traditional software can't directly apply to GUI.This paper analyses interaction between GUI events,researches on why some events can lead to defects and gives a cost-effective Event Interaction Graph(EIG) based GUI automated regression test framework and corresponding regression test process,which is used to provide the best combination of defect detection rate and cost.
