TestNg not executes @BeforeGroup if the method is in another class

Question

My code structure is like this... I have 4 classes having 10 tests and one @BeforeClass method to run before any of the test.In each of 4 classes ,all tests are of one single group.

And I have one another class which I need to run before that @BeforeClass method in 4 of the tests.

How do I achieve that.Please help

Answer 1

"And I have one another class which I need to run before that @BeforeClass method in 4 of the tests."

To achieve:

Just make all of the 4 class extend this "AnotherClass" and add @BeforeClass annotation in the constructor of this class.

Hope this will help.
