Final answer:
To create test cases, you would refer to requirements specifications, design specifications, and use case documents, among others. The medium to prepare this information can be a traditional written document, slide deck, or video presentation, depending on the project's needs.
Step-by-step explanation:
When creating test cases, you would typically refer to several key documents that provide the necessary information to understand what needs to be tested and how. Among these are the requirements specifications, which outline what the software is supposed to do; the design specifications, which describe how the functionality will be implemented; and any use case documents, which provide detailed scenarios of how the system is used.
Other documents that might be consulted include product documentation and user stories, if you're following an agile methodology. Depending on the project, you might use different mediums to prepare this information, such as traditional written documents, a slide deck, or video presentations. The choice of medium depends on the project's needs, team preferences, and the complexity of the information to be conveyed.
