In the past, we've relied on Liquibase to generate dummy records for the primary database tables. This was originally done to allow us to quickly and (somewhat) efficiently perform API test (with a focus on regression testing).
More recently, our API test infrastructure has increased to the point where we can just write brief (JUnit) API tests which can be run against our test environments to easily insert data (via the proper API pathways). Because of that, we've been moving away from predefined test data. (Using 'production' data isn't really something that applies to our specific situation)
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
