Github user Leemoonsoo commented on the issue: https://github.com/apache/zeppelin/pull/1846 [AuthenticationIT.java](https://github.com/apache/zeppelin/blob/master/zeppelin-server/src/test/java/org/apache/zeppelin/integration/AuthenticationIT.java) is test that uses zeppelin with shiro enabled. However it's selenium test and bit difficult to make. I think it's possible to make unittest by calling methods in InterpreterFactory class, directly. Like [this test](https://github.com/apache/zeppelin/blob/master/zeppelin-zengine/src/test/java/org/apache/zeppelin/interpreter/InterpreterFactoryTest.java#L148). Let me know if you need any help.
