You struggle since you are not doing TDD - you are currently adding unit tests afterwards instead of before. Using TDD "by the book" means: work with extremely short cycles of . think of the next requirement/change you want to implement; write a test for exactly that requirement; run the test (gives you typically "red")

Mock data is also prepared during these steps. Certain test scenarios require mock test data to comply with data privacy/security requirements. For example, if you are testing the login page, you should not use real user credentials to run the tests. Instead, QA teams usually have a synthetic dataset that can be fed into the test cases.
