Unfortunately, this is not generally possible. The base class could be
there when using JUnit. However, when using TestNG with Arquillian, the
class needs to extend org.jboss.arquillian.testng.Arquillian. i.e.:

class TestClass extends Arquillian { ... }

(look at an example:
https://github.com/mgencur/infinispan-arquillian-container/commit/4fdfab2273e30e0592fb308f3407c9d40e3a8419#diff-7) 

This is due to TestNG itself (if does not allow Arquillian to modify
TestNG's behaviour via events to completely suit Arquillian's needs, so
Arq needs a base class that will help him with it - laicly said :-)
