Robotic Process Automation in automated GUI testing of Web Applications

Sammanfattning: To ensure that the web applications we use in our daily life work as intended, thorough testing is essential. Testing of the Graphical User Interface (GUI) is one of the more challenging parts of software testing and is often a manual process. There are several ways to automate GUI testing. Robotic Process Automation (RPA), a recent technology where a software robot mimics the actions of a human operator, has been suggested as a method of improving automated GUI testing. This thesis study investigates the viability of using an RPA-based approach for automated GUI testing of web applications by evaluating how well it compares to a dedicated software tool developed specifically for automated GUI testing in terms of performance and user experience. This thesis study presents an RPA-based approach using UiPath for testing the GUI of web applications and compares it with an approach using Selenium IDE. To compare the two approaches, a web application provided by Sellpy is used as the application under test. A set of test cases is created based on a user-flow analysis. The test cases are implemented using each approach and performance in terms of execution time, number of flaky tests, and code footprint is evaluated for each approach. In addition, a user study is conducted to evaluate and compare the user experience when using each approach. The results show that an RPA-based approach can be used for automated GUI testing of web applications. The RPA-based approach managed to achieve the same amount of testing coverage. In terms of performance, the results in this study show that the approach using Selenium IDE outperforms the RPA- based approach in both execution time and code footprint. On the other hand, the RPA-based approach had fewer number of flaky tests. The test subjects preferred the RPA-based approach, but the study showed that the difference was not statistically significant. Based on the results, we draw the conclusion that an RPA-based approach using UiPath can be used in automated GUI testing of web applications. However, we suggest more research aimed at investigating long-term usage.
