Topic: Challenging innovative test automation tool in an industrial setting

A test automation tool that has an innovative approach at the Graphical User Interface (GUI) level. We did a scientific research in the Dutch rail sector to compare this innovative approach to the used manual approach. We developed a scientific framework to make the compare possible. In this research, two perspectives have been conducted to investigate the sensemaking and technological value of GUI test automation tool. ‘Sensemaking’ is the process by which people give meaning to events. The innovative test automation tool is a traversal-based and scriptless approach (without test cases) make it different from other GUI testing tools. Moreover, this tool it automates not only the execution of the tests, but also test design. Since no test scripts are needed, it is expected that this innovative tool solves a significant part of the maintenance problem from which other approaches suffer. At present, a limited amount of studies has examined how effective, efficient, learnable and satisfactory the innovative approach is in an industrial setting. The results can provide sufficient information to help companies judge if a specific technology being evaluated will benefit their organization. Our case study compares the innovative test automation approach without test cases to a manual test approach within a realistic industrial setting (rail sector) with a real mission critical web-based software application. Both qualitative and quantitative research methods are used to investigate learnability, effectiveness, efficiency, and satisfaction. Beside this factor we also analyzed the sensemaking of the test automation tool. The results show that within this setting, the innovative test automation tool was able to detect more faults and had a higher functional test coverage than the used manual test approach.
