Testing is an essential activity associated with web applications and systems to make sure that there are no defects present within the same. It also highlights certain areas that can be improved to serve customers better.
Validation and verification are the techniques that are used to test a particular system. Cognitive Walkthroughs are one of the validation techniques that are used under the domain of software testing. It is a testing process that is executed by a group of evaluators and the execution is done from the perspective of new and infrequent users. The system behavior is then analyzed from the perspective of such users and the results are reported thereafter (Lewis, 1994).
A cognitive walkthrough of the Goaling application was done previously covering the various functionalities such as login, registration, application options and holidaying. There were numerous user stories that were created and the test cases along with their results were reported in the form of a table comprising of the scenarios, steps to reproduce, expected behavior and actual behavior. The walkthrough brought out the perspective of the new and infrequent users in terms of their expectations from the system. It also highlighted the expected system behavior in most cases.
However, the focus of the previous walkthrough was primarily on the application functionality and behavior. The user interface and system qualities were not analyzed extensively in the previous cognitive walkthrough of the application. The primary aim of the cognitive walkthrough is to understand the expected level of visual appeal and look and feel from the user’s perspective which was not covered in-depth in the previous iteration.

The quotations that are displayed at the top of the list of options shall change randomly after a certain time period. Also, the color scheme shall be kept consistent across all the screens. For instance, Goaling screen displaying the goals makes use of black, white and grey whereas ‘holidaying’ screen uses red, green, and white. Color scheme shall be kept consistent and user shall be allowed to customize and personalize the same. On the holidaying screen having the calendar under the random checklist option, there is a slight overlapping of the calendar on the buttons underneath. There shall be a little bit of gap present in between the two UI components.
