TestRigor is a test automation tool designed to enhance user experience on websites, exemplified by a demo for Mike's Bikes, by methodically exploring site functionality, clicking links, and capturing screenshots of user paths. Users begin by adding a new application in TestRigor, specifying details such as browser type and login credentials if needed. The tool offers customization options for test speed, including adjusting timeouts for server response, page load, and page rendering, which can be optimized for different network conditions or page complexities. Once configured, TestRigor's crawler navigates the website, identifying user-interactive elements like product links and checkout buttons, while generating screenshots to document each navigational choice. As changes are made to the site, the Retest feature allows TestRigor to detect and evaluate new functionalities, giving users the chance to review them as successful or identify potential bugs.
