Eclipse (with Pydev) keeps throwing SyntaxError

As MasterAndrey has mentioned, pytest_ignore_collect should do the trick. Important to note that you should put conftest.py to root folder (the one you run tests from).
Example:

import sys

def pytest_ignore_collect(path):
    if sys.version_info[0] > 2:
        if str(path).endswith("__py2.py"):
            return True
    else:
        if str(path).endswith("__py3.py"):
            return True

Since pytest v4.3.0 there is also --ignore-glob flag which allows to ignore by pattern. Example: pytest --doctest-modules --ignore-glob="*__py3.py" dir/
