Chapter 2. Persisting Data and Testing

In this chapter, you will see how you can write executable specifications for your web service and how Play can integrate mainstream data persistence technologies like RDMSes or document stores. More precisely, you will see how to perform the following:

  • Write and run unit tests
  • Simulate HTTP requests and inspect returned HTTP responses
  • Persist data using an RDBMS
  • Use an in-memory database for development
