Configute tox.ini to ignore library during tests with py27

I have the following tox.ini configuration file:
# Tox (http://tox.testrun.org/) is a tool for running tests
# in multiple virtualenvs. This configuration file will run the
# test suite on all supported python versions. To use it, "pip install tox"
# and then run "tox" from this directory.

I have update my requirements.txt file in order to upgrade the version of Marshmallow from 3.0.0b14 to 3.10.0; like this:
https://github.com/wazo-platform/wazo-lib-rest-client/archive/master.zip
https://github.com/wazo-platform/wazo-auth-client/archive/master.zip
https://github.com/wazo-platform/xivo-bus/archive/master.zip
cheroot==6.5.4
flask==1.0.2
netifaces==0.10.4
psycopg2==2.7.7
pyyaml==3.13
python-consul==1.1.0
marshmallow==3.10.0
six==1.12.0
stevedore==1.29.0
Now my problem is that, when I run tox -e py37 everything works fine, but when I run this command tox -e py27, it fails. I get that the issue is that Marshmallow 3.10.0 is not supported on Python 2.7; so what I want to do is to change the tox.ini file in order to ignore Marshmallow library tests when it comes to running this command tox -e py27. I am new with tox, so I am not sure how to do this. Any help is welcome, thanks.

You need to mark those "Marshmellow" tests with a pytest marker.
https://docs.pytest.org/en/6.2.x/example/markers.html
e.g.
#pytest.mark.marshmellow
def test_xxx():
...
And then you need to run pytest -m "not marshmellow".
As you only want to do this for Python 2.7, you'd need to create a new testenv.
e.g.
[testenv:py27]
commands = pytest -m "not marshmellow" ...

The last version of Marshmallow that supports Python 2.7 is 2.21.0. You can mark your requirements.txt to install different versions of Marshmallow for different versions of Python:
marshmallow<3; python_version == '2.7'
marshmallow==3.10.0; python_version >= '3.6'
See https://www.python.org/dev/peps/pep-0496/

Never use # to suppress echoing makefile commands until you are sure that the makefile is working correctly. And even then, consider not doing so.
Also, I urge you to avoid putting ANSI escape sequences into your makefile. They are obnoxious to read, and they will not be effective in all contexts. Absolutely omit them from any makefile you present here, as they are not part of any minimal reproducible example unless it is asking specifically about them.
Anyway, this problem ...
process_begin: CreateProcess(NULL, python3.8 -c "import sys; print(sys.version_info[:2] >= (3, 8))", ...) failed.enter code here
Makefile:24: pipe: Bad file descriptor
... appears to be a consequence of this problem ...
FATAL Python not found (python3.8)
. The messages are ordered that way in the output because that is the order in which they are generated, reflecting a deep flaw in your approach.
GNU make directives, such as ifeq, are evaluated when the makefile is parsed, before any recipes are run. Thus, this code ...
ifeq (, $(shell which ${PYTHON} 2> /dev/null))
#printf "\033[38;5;220mFATAL\033[0m \033[38;5;196mPython not found (${PYTHON})\033[0m\n"
#exit 1
endif
... does not halt the build immediately if the requested Python interpreter is not found. The exit command is part of a recipe, which isn't (yet) being run. As a consequence, make proceeds to evaluate the next directive either way:
ifneq (True, $(shell ${PYTHON} -c 'import sys; print(sys.version_info[:2] >= (3, 8))'))
. If indeed ${PYTHON} was not found, then the shell command being executed fails with the error reported, but, occurring as that does inside an execution of the $(shell) function, that does not terminate the build. Make decides to build the ${VENV} target, and when executing the recipe for that target, it finally gets around to printing the "FATAL" message and executing the #exit 1 guarded by the above ifeq. That causes make to stop the build and report that the recipe for .venv (== ${VENV}) had an error.
I've created a venv before running and installed python8.3, pip as well.
Notwithstanding what software may or may not have been installed, whatever shell make uses to execute the $(shell) function (which it will also use to execute recipes) does not have a command python3.8 in its executable search path. There is not enough information provided to troubleshoot that further.
Also, make does not see a subdirectoy .venv in its working directory, for it would not otherwise be executing the recipe for the .venv target. If that surprises you, then possibly it results from running make from the wrong working directory. Not much more can be said about that, either.
Overall, I think you're trying too hard, at least on the make side. I would just let the execution of ${PYTHON} in a recipe fail if need be, having not suppressed command echoing. The makefile would be easier to write, and the diagnostic output easier to interpret.

Your reported problem is actual a problem in Python 3.5.0!!
You can check your Python 3.5 version by entering a command like python3.5 --version or just enter python3.5 and have a look at the top of the repl output.
You can resolve the problem by installing the any higher point release of Python 3.5, e.g 3.5.1 or the even the latest one, 3.5.10.
This all said - Python 3.5 is already end of life ( https://www.python.org/downloads/ ). If there is no important reason, please consider to drop support for it.

poetry dependencies not available when running script with tox

I have a python project that uses poetry and tox. It has source code, tests and scripts (juptext notebooks). I can't import the dev dependencies in the scripts, but I can in the tests.
When I came across this problem, I created the following minimal example. At first, it didn't work, then I fiddled around with it, and now it's working. So I stripped the project that has the actual problem down so it's indistinguishable other than the project name, location, virtual env, and .git directory, but that's still not working.
UPDATE deleting all build artifacts and the virtualenv for the minimal example makes it stop working again
UPDATE adding the line scripts: poetry install to the tox commands fixed only the minimal example
The source code, tests and scripts are in the following layout
foo
+--foo
| +--__init__.py
|
+--tests
| +--__init__.py
| +--test_foo.py

envlist = py37
isolated_build = True
skipsdist = True
[testenv]
whitelist_externals = poetry
commands=
poetry run pytest
optionally you can make the install happen on running the tests by changing the last bit to (but then you will need to have tox installed outside of poetry, which could cause you issues down the line)
commands=
poetry install
poetry run pytest
Also depending on your root folder and where the tests are you can configure the path for tox to change directory to by adding
changedir = tests
In which case the whole file would look like this if you are in directory foo executing tox:
[tox]
envlist = py37
isolated_build = True
skipsdist = True
[testenv]
whitelist_externals = poetry
commands=
poetry run pytest
changedir = tests

This is an easy fix. First, run rm -rf .tox to delete the .tox directory, probably hasn't installed the files you wanted.
Here is an example of my tox.ini.
[tox]
isolated_build = true
skipsdist = true
envlist = py39
[testenv]
deps = -rrequirements-dev.txt
whitelist_externals =
poetry
skip_install = true
commands =
python -m pytest tests/
As you can see in the tox.ini file I have a separate requirements for dev. This can be generated from poetry via the commands below.
poetry export --format=requirements.txt --without-hashes --with dev --output=requirements.txt
poetry export --format=requirements.txt --without-hashes --output=requirements-dev.txt
Don't ask me why but the deps in [testenv] are concatenated out, as you can see with deps = -rrequirements-dev.txt, would also change your command to python -m pytest /tests
Ciao.

First I need to install the dependencies with poetry install. Then append poetry run to the beginning of the command to enable the dependencies. Also running python scripts like that will just run the first, passing the name of the others as args to the first program. Instead use for f in scripts/*.py; do python "$f"; done (see here)
All together
poetry install
poetry run bash -c 'for f in scripts/*.py; do python "$f"; done'

How to use wildcard in command prompt while executing the pytest test cases

I have below project structure in Pycharm.
Project Folder: PythonTutorial
Package: pytestpackage
Python Files: test_conftest_demo1.py, test_conftest_demo2.py
I'm trying to run the above 2 python files having almost similar name using pytest from command prompt with the below command. But I'm facing the below issue. Please help me on the same.
Note: I'm using windows 10 operating system .
Command Used:
py.test -s -v test_conftest_demo*.py

use the -k option to specify substring matching.
$ pytest -s -v -k "test_conftest_demo"
