Functional vs. Data Testing: Don't Own Your Clients' Data
Now that automated testing is common in the development world, there is a misconception that it can be used for brute force approaches to cover all your bases. This leads to business owners wanting to test every scenario with their data. This brute force approach is not only time-consuming, but it is not scalable, and can expose your company to PHI and PII issues.
Doug Noël, Principal Engineer at Optum, takes a look at separating out data testing from the functional testing at the core of your product, and then re-investing that time into solid ETL testing that will satisfy your customers without exposing sensitive data.
