The process of converting the editor ( https://github.com/jpfxgood/ped ) to Python3 and writing tests is going well. I am fixing a LOT of minor bugs and edge conditions that don’t really come up a lot in my normal use of the editor but are very evident doing detailed test cases. I came up with some cool ways to test features that are only available interactively by using the keyboard macro feature of the editor to feed the required interaction to the editor main processing loop. It reminds me of testing 1-2-3 for DOS where virtually all of the testing was done with keyboard macros and screen comparisons. It also tests the macro feature, and it already helped me fix a hidden bug in the macro feature where it was accumulating null characters when no key was being pressed. If one left macro record on it would have eventually sucked up all of the heap memory, though I guess it would have taken a while on modern machines. I may have to refactor the main test function since it is getting pretty long, I’ll see where it’s at when I finish.
Oh and running pytest inside VSCode is wonderful for debugging both the code under test and the test automation at the same time.
Here’s the simple launch config that I use:
{
// Use IntelliSense to learn about possible attributes.
// Hover to view descriptions of existing attributes.

"version": "0.2.0",
"configurations": [
{
"name": "Python: Current File",
"type": "python",
"request": "launch",
"program": "${file}",
"console": "externalTerminal"
},
{
"name": "Python: Pytest",
"type": "python",
"request": "launch",
"module": "pytest",
"console": "externalTerminal"
}
]
}If you want to watch the tests run I have this handy screen recording:
