Step-by-step explanation:
Yes, a typical user story should include tests as part of its cost estimate. Including tests in the cost estimate is important for ensuring the quality and reliability of the software being developed. Tests help identify and catch any bugs or issues in the code, reducing the overall cost of development by minimizing the need for rework or fixes later on.
Tests also provide a clear definition of what is expected from the software, making it easier to prioritize and plan the development process. Additionally, including tests in the cost estimate helps in estimating the effort and resources required for testing activities, ensuring that adequate time and budget are allocated for testing.
