Currently, We are using Liquibase to resolve this issue. As Developer, You know feature you are implementing and you already tested with a different combination of data (If you are a good developer!). With liquibase we added one more step in our process that each developer will write liquibase changeset to insert/update/delete data by which they performed the test. We have profile setup so this changeset will only run in dev context.
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.
