@BeforeClass and inheritance - order of execution

Question

I have an abstract base class, which I use as a base for my unit tests (TestNG 5.10). In this class, I initialize the whole environment for my tests, setting up database map

Answer 1

A better and cleaner way to achieve this using inheritance may be as following -

abstract class A {

    @BeforeClass
    void doInitialization() {}
}

class B extends A {

    @Override
    @BeforeClass
    void doInitialization() {
        super.doInitialization();
    }

    @Test
    void doTests() {}
}
