##-------------------This one is invoking constructor ----------------##

##--Please help ---

Hi , I think the recommended way is to put pytest function with in class.

def test_landing_page_functionality_one():
print("Inside functionality one test cases")
# print(driver.session_id)

def test_landing_page_functionality_two():
print("Inside functionality two test cases")
# print(driver.session_id)

def test_landing_page_functionality_three():
print("Inside functionality three test
# print(driver.session_id)

I am assuming that pytest functions are needed to be kept outside class declaration.

Hey,

Thank you if you are providing a different work around for the issue. If there is a question inside the whole query, then I didnt understand it properly.
