[Python] How do I correctly setup and teardown for my pytest class with tests?

I am using selenium for end to end testing and I can't get how to use setup_class and teardown_class methods.

I need to set up browser in setup_class method, then perform a bunch of tests defined as class methods and finally quit browser in teardown_class method.

But logically it seems like a bad solution, because in fact my tests will not work with class, but with object. I pass self param inside every test method, so I can access objects' vars:

class TestClass:

def setup_class(cls):
pass

def test_buttons(self, data):
# self.$attribute can be used, but not cls.$attribute?
pass

def test_buttons2(self, data):
# self.$attribute can be used, but not cls.$attribute?
pass

def teardown_class(cls):
pass



And it even seems not to be correct to create browser instance for class.. It should be created for every object separately, right?

So, I need to use __init__ and __del__ methods instead of setup_class and teardown_class?
