Finite State GUI Testing with Test Case Prioritization Using Z-BES and GK-GRU

Abstract

To deliver user-friendly experiences, modern software applications rely heavily on graphical user interfaces (GUIs). However, it is paramount to ensure the quality of these GUIs through effective testing. This paper proposes a novel “Finite state testing for GUI with test case prioritization using ZScore-Bald Eagle Search (Z-BES) and Gini Kernel-Gated recurrent unit (GK-GRU)” approach to enhance GUI testing accuracy and efficiency. First, historical project data is collected. Subsequently, by utilizing the Z-BES algorithm, test cases are prioritized, aiding in improving GUI testing. Attributes are then extracted from prioritized test cases, which contain crucial details. Additionally, a state transition diagram (STD) is generated to visualize system behavior. The state activity score (SAS) is then computed to quantify state importance using reinforcement learning (RL). Next, GUI components are identified, and their text values are extracted. Similarity scores between GUI text values and test case attributes are computed. Grounded on similarity scores and SAS, a fuzzy algorithm labels the test cases. Data representation is enhanced by word embedding using GS-BERT. Finally, the test case outcomes are predicted by the GK-GRU, validating the GUI performance. The proposed work attains 98% accuracy, precision, recall, f-measure, and sensitivity, and low FPR and FNR error rates of 14.2 and 7.5, demonstrating the reliability of the model. The proposed Z-BES requires only 5587 ms to prioritize the test cases, retaining less time complexity. Meanwhile, the GK-GRU technique requires 38945 ms to train the neurons, thus enhancing the computational efficiency of the system. In conclusion, experimental outcomes demonstrate that, compared with the prevailing approaches, the proposed technique attains superior performance.
