Port PyUnit/UnitTest module #44
Description
Activity
Sorry, I didn't look on porting this, and currently I'm really busy with lessons and work. If you want you can take on it, I don't think it should be too dificult since PyUnit/UnitTest module is written in pure python...
I'd love to take a shot on this. I'm fairly new to C development but pretty fluent in Python, so I surely would learn a thing or two :)
Please don't doubt on ask me anything :-)
If it's written in pure Python (v3) then it would be a good way to test uPy itself, to see how well (or not!) it conforms to Python.
@piranna I think I misunderstand you.
PyUnit is the name for the python unit testing framework - which is exposed in python 3.3 as the unittest module.
docs here: http://docs.python.org/3/library/unittest.html#module-unittest
It appears in your python 3.3 source tree inlib/unittestas a pile of python files.unittest2 is a backport of unittest for python 2.4, 2.6 but as the python is in 3.3 version - why do suggest unittest2 ?
I know I'm missing something, apologies in advance.@piranna I think I misunderstand you.

I know I'm missing something, apologies in advance.I proposed unittest2 because I didn't know where the PyUnit/unittest code
integrated on Python source code was, but both should be equivalent if not
the same. If the integrated one is located at lib/unittest, don't doubt it
and use it since it's the official, good one.This kind of things is why I don't understand the reason python modules are
not in an independent source tree in CPython, you can't be able to locate
and reuse them easily on other projects. Maybe we could start doing it us
on MicroPython putting the ported modules like unittest in an independent
repo (github.com/micropython/python-modules, for instance)?I'm facing problems now. Currently uPy's
importstatement is very minimal. It only importsmod_name.py, no support formod_name/__init__.pynorimport mod_name.SomeClassorfrom mod_name import SomeClass(the last two result in failed asserts incompile.c, line 1197).I was able to let uPy try to import
mod_name/__init__.py, but am struggling with the rest. I'll propably will have to wait, until we have a more powerfullimport(or use a big fat file without any imports -- but who would want that?).Note that I'm working on import code to support sys.path. We apparently need to get decent module import support before going to support packages. But you're of course welcome to prototype how it would work - it won't appear on its own, someone who needs it will need to implement it (and my guess that MCU usage which is direct target of uPy can live happily without packages for quite some time).
What about a python testing library running on the pc using full python , controlling the board through an remote procedure call ?
This way , we'll get remote procedure call library and an ability to test python using more testing tools(for example quickcheck ) and the full power of python ?
There is now a way of doing RPC on the pyboard: you can enter raw REPL mode by using CTRL-A. This allows you to send arbitrary Python code to the board over the USB serial connection, and get the result back. I have written a small Python class that runs on the PC, which allows you to do pyboard.exec('....') and pyboard.eval('...'). I'll add it to the repo after I tidy it up.
Sweet
I just pushed getattr() implementation, which was another missing piece to implement this stuff.
RPC on the pyboard now exists as tools/pyboard.py

It's the standard Python test library, and this way the tests would be done in an automatically way directly from inside the board... :-)
