I finally was able to get Visual Studio Code set-up correctly to run and debug unit and integration tests for a Python 3.8 project that I am working on (I’ll add a link to that post here once it is up).
After making some changes to the code and adding a test I got the following error when trying to debug the test:
Test result not found for: ./mylibs/integration_tests/myclient_integration_test.py::MyClientIntegrationTest::test_happy_path
? An odd error message, to be sure.
After a little → Continue reading “VS Code “Test result not found for:” When Running Tests for a Python Project [SOLVED]”
The following should work with just about any version of Python. I am using it to compile, currently 3.10.x, on distros where those packages are not readily available for installation. The following is a quick how to on getting it compiled under both RedHat/CentOS/Almalinux and Debian based systems.

I regularly use Python Invoke and Fabric for the automation of various tasks; from deploying code to developing my own set of tools for various projects. Following is an example on how to write a
launch.json launch configuration for vscode so that you can step through the tasks.py code and debug it.
Assuming that you have created a virtual environment and pip installed invoke into it. And, assuming that you have defined a task in your tasks.py file as follows:→ Continue reading “Creating a Launch Config in VSCode to Debug a Python Invoke Script”
I’ve written a number of Python apps where I would like it to print some sort of counter or progress bar to STDOUT to let me know that it is still running instead of locked up or died somehow without me being able to see it.
I had tried using a couple of different existing progress bar related modules but none of them really worked except in a very specific use case.
So, after a bit of futzing around I → Continue reading “Creating a Counter or Progress Bar for a Python Program”
A common design pattern is to define a class or list of classeses in configuration such that at runtime the classes can be dynamically instantiated.
I’ve done this before in many other languages and had need to do so today in Python (2.7.11)
It seems as though the clean way to do so is by using the Pyton importlib module. By using it, it enables you to cleanly dynamically import sub modules
Following is an example:
