2. Challenge

3. Assume

4. Before deploying we would like to test

5. Solution: dropwizard-testing-integration
End-to-end service test as opposed to unit and resource
tests:
- Allows you to start and stop the dropwizard instance
programmatically
- Compatible with DW 0.62
- Use it to run integration tests in your build

6. Example: setup

7. Example: teardown

8. Example: tests

9. How to get it?

10. Caveats
• We needed to hack a bit, to reset static state.
• Flaky with more than one instance being started at the
same time.
• Only tested to work with DW 0.62
• Be careful how you pull in dependency clients

11. Future
• Integrate the functionality into DW
• Would be useful if DW had no static state
