Pytest - test case execution order

Question

I have some scripts with the tests for them and I need to run these tests in execution order explicitly defined by me.

It looks like:

# one.py
import some lib

class Foo():
    def makesmth(self)
        script

then I have made test files:

# test_one.py
import pytest
import some lib

class TestFoo():
    def test_makesmth(self):
        try/except/else assert etc.

So it looks simple and right. When I run file test_one.py everything is ok. Package of my scripts-testing looks like:

package/
|-- __init__.py
|-- scripts
|   |-- one.py
|   |-- two.py
|-- tests
|   |-- test_one.py
|   |-- test_two.py

When I try to collect test with

pytest --collect-only

it is giving non-alphabetical and just randomly order of tests.

Where I can write information about order of tests? Non-alphabetical, just like I want to start test like b, a, c, e, d - and not random not alphabetical

Tried to made file tests.py:

import pytest

from tests.test_one import TestFoo
from tests.test_two import TestBoo etc.

And when I'm trying to run this, errors are shown, because these imports were done in the way I don't understand (tried to make aTestFoo bTestBoo and also rename test files in that method definition way but still it's doesn't work).

Pytest-ordering seems abandoned at the moment, you can also check out pytest-order (a fork of the original project).

import pytest

@pytest.mark.order(2)
def test_foo():
    assert True

@pytest.mark.order(1)
def test_bar():
    assert True
