Java SDK source contains source set with integration tests that can be run against real PubNub application. In order to run integration tests make sure the dedicated App is created on PubNub's Admin Portal. To launch integration tests use Gradle's integrationTest task. Before doing this make sure correct Subscribe Key is configured in test.properties file in project's root directory. See contents of test.properties.example for more details.

Parameters from test.properties file can be overriden by setting corresponding environment variables. Example:

> export subKey=<SUBSCRIBE_KEY>
> ./gradlew build integrationTest

In current version those tests are not plugged into CI pipeline and they need to be launched on demand.
