User interface (UI) evaluation is an important aspect of software development, ensuring that software or systems are efficient and user satisfactory. Among the various usability testing methods available, Cognitive Walkthrough Method, Heuristic Evaluation Method and Concurrent Usability Testing Method stand out as most popular approaches. This research paper presents a comparative analysis of these testing methods, emphasizing their strengths, flaws, and applicability in different situations. Through a detailed analysis of each testing method's procedural steps, and practical concerns, we aim to provide insights into their effectiveness and suitability for evaluating User Interface (UI) designs. Additionally, we discuss potential synergies and inadequacies when combining these testing methods in practice. Our results and findings contribute to a deeper understanding of UI evaluation techniques and provide guidance for selecting the most appropriate approach for testing team’s specific needs.
