 Check out our [documentation](http://docs.launchdarkly.com) for in-depth instructions on configuring and using LaunchDarkly. You can also head straight to the [complete reference guide for this SDK](http://docs.launchdarkly.com/v1.0/docs/java-sdk-reference) or our [Javadocs](http://launchdarkly.github.io/java-client/).
 
+Testing
+-------
+
+We run integration tests for all our SDKs using a centralized test harness. This approach gives us the ability to test for consistency across SDKs, as well as test networking behavior in a long-running application. These tests cover each method in the SDK, and verify that event sending, flag evaluation, stream reconnection, and other aspects of the SDK all behave correctly.
