Abstract GUI systems are becoming increasingly popular thanks to their ease of use when compared against traditional systems. However,
GUI systems are often challenging to test due to their complexity and special features. Traditional testing methodologies
are not designed to deal with the complexity of GUI systems; using these methodologies can result in increased time and expense.
In our proposed strategy, a GUI system will be divided into two abstract tiers—the component tier and the system tier. On
the component tier, a flow graph will be created for each GUI component. Each flow graph represents a set of relationships
between the pre-conditions, event sequences and post-conditions for the corresponding component. On the system tier, the components
are integrated to build up a viewpoint of the entire system. Tests on the system tier will interrogate the interactions between
the components. This method for GUI testing is simple and practical; we will show the effectiveness of this approach by performing
two empirical experiments and describing the results found.
