The purpose of using the Test Cases template in UiPath is to provide a standardized format for documenting and organizing test cases. These templates serve as base models for test cases and can include data variations to be reused in different tests. They are particularly useful in Test Automation projects, where they can help ensure consistency and efficiency in the creation and execution of test cases. The templates can include other file types such as Global Exception Handler, and they are specific to the project type and the language used to create them1.
