Unit Testing LVGL+micropython code

[mark-hoy]

I have searched and "unittest" was at one point (in 2018 with micropython-unittest 0.4) working with micropython. However, a lot has probably changed since then and I was wondering what other people do for unit testing there micropython+lvgl code.

I have code that now runs on an embedded ESP32 screen along with on my MacOS and Linux systems. Not everything is perfect though. As I also need a way of using a serial port on my Mac/Linux box with micropython to more faithfully emulate the ESP32 device (which talks to another device via it's serial port).

Suggestions welcome.

I think I have found my answer, there is a unittest in lib/micropython/lib/micropython-lib/python-stdlib/unittest that is usable with Micropython. I was unsure how to make a library out of it as there are a couple of items in the library.

This was solved when I stumbled upon the Micropython Install Packages which showed me the packaging (and also placed a copy in ~/.micropython/lib/unittest)

The micropython unittest is missing mock funcationality.

There is a umock that is missing async functionality, but seems like a reasonable start for using mock with the micropython unittest. (Work I still have to try and do).

There is also umock but it hasn't been modified since 2019 and looks to be an initial version 0.0.1.

I am guessing another step is to understand the manifest.py file to add frozen libraries to my build.
