The Test didn't registered with OVM factory

Recently I have seen a test which is extended from OVM_TEST. But they didn’t register that extended test with `ovm_component_utils. I asked him and he told me that we are registering the tests whichever extended from that base test, so no need to register that base test with ovm factory. Does it works ?

If yes, can we follow same thing in sequence ?

In reply to Rudra Rao:

This is not correct. Both the base and the extended classes must be registered with the factory if you want to use them with the factory.

In reply to dave_59:

Can I register that class in some another class within that package ?
