Ephemeral Testing

Eric Leimer discusses the concept of ephemeral testing, a testing approach that involves creating temporary test data and environments to ensure software reliability. He proposes using ephemeral databases, which can be created and destroyed quickly, to test software without affecting production data. This approach can reduce the risk of data leakage and improve the speed of testing. Leimer also suggests using ephemeral storage and temporary test environments to further isolate testing from production. He provides examples of how to implement ephemeral testing using Docker and AWS, and notes that this approach can be particularly useful for testing database-driven applications.
