-------------------------------------------
> 4. Then, create virtual environments within jenkins' workspace folder via:
> python3.x -m venv ...
https://github.com/apache/beam/pull/15819 makes this change. Let's see how that
works first. We can later switch Jenkins workers to use PyEnv, perhaps when we
have to upgrade the Ubuntu image.

> Project: Beam
> Issue Type: Sub-task
> Components: sdk-py-core, testing
> Reporter: Valentyn Tymofieiev
> Priority: P3
> Time Spent: 14h
> Remaining Estimate: 0h
>
> Currently, Beam Python test infrastructure does not provide fine-grained way
> to control Python interpreter version. The major+minor version are typically
> selected by virtual environment, and the patch version of interpreter is
> defined by the version of python package available on machine that is running
> the tests.
> For example, Jenkins ubuntu-based machines, use Python 3.5.2 for python 3.5
> test suites, while debian-based SDK harness containers for Python 3.5 come
> with Python 3.5.6, and the python3.5 package available on my dev machine is
> Python 3.5.4.
> Throughout development of Python 3.5.x, Cpython implementation details that
> have changed in and these changes affect certain codepaths in Beam, such as
> type inference.
>
> When we encounter such issues, it is difficult for Beam developers to test
> their changes against a particular patch version of Python interpreter both
> remotely and locally. Opening this issue to make it simpler.
> cc: [~markflyhigh] [~yifanzou] [~udim] [~altay] who may have opinions and
> ideas about how to make this simpler.
> Note that there are separate questions:
> 1) which patch versions of Python we should test against on Jenkins
> 2) which patch versions of Python Beam should claim to support.
> Regardless of the answers to those questions, we may want to make it easier
> for an engineer to run a test suite against a particular patch version of
> Python, and/or make it easier to switch which patch version is used by
> Jenkins.
