help - documentation improvement - grouping test by class - how to share values

Following this example https://docs.pytest.org/en/latest/getting-started.html#group-multiple-tests-in-a-class i would like to make a test workflow. the second test needs result obtained from the first test. i’m not able to share these information.

i’m using python 3.7.4 and pytest-5.2.1

as you can see,

even if i set a parameter to the class, this parameter look like already evaluated when the second test start.

import pytest
@pytest.mark.incremental
class TestUserHandling:
    id = "1"
    def test_login(self):
        print("id value --> " + self.id)
        self.id = "2"
        print("id value --> " + self.id)
        pass

    def test_modification(self):
        assert self.id == "2", "self id value is " + self.id

first test returns

b__test_step.py::TestUserHandling::test_login PASSED
id value --> 1
id value --> 2

second test returns

AssertionError: self id value is 1
1 != 2

second test needs data from the first test to make the job.

how can i obtain this behaviour?

thanks.

currently the setups im involved in do workflws&co by just setting up the dependencies for each test in fixtures, even if its expensive in some ways, and then use caching7scopes to sort out the cost

thanks for the follow-up
