Scenario for a Use Case: Using a Test Data Profile that contains a set of usernames and passwords, multiple Login information are fed into a single Test phase. That way, we can categorize test data into three buckets: valid data, invalid data, and extreme data. The benefit of this kind of data generation is that the data generated by automation (automated testing) will be of high quality and accuracy. Quantitative variables are any variables where the data represent amounts (e.g. Many of these people were enrolled right after getting COVID, so it was too soon to know whether they would develop long-lasting symptoms.
