Create tests for turtle module

[adorilson]

turtle module has too few tests.

These are the module's public classes to review if there are test and/or implement them:

• [ ] RawTurtle
• [ ] ScrolledCanvas
• [ ] TNavigator
• [ ] TPen
• [ ] Tbuffer
• [ ] Terminator
• [ ] Turtle
• [ ] TurtleGraphicsError
• [ ] TurtleScreen
• [ ] TurtleScreenBase
• [ ] Vec2D

Some random notes:

1. For those going to work on teleport, see https://github.com/python/cpython/pull/107807#pullrequestreview-1584010411

Here, go the module's functions:

• [ ] Screen
• [ ] config_dict
• [ ] demo1
• [ ] demo2
• [ ] getmethpartlist (WIP: https://github.com/python/cpython/pull/135533)
• [ ] read_docstrings
• [ ] readconfig
• [ ] switchpen
• [ ] write_docstringdict

Are you willing to work on this one? if so, I can assign you the issue

Hi @picnixz @adorilson Can I help you with this?

[picnixz]

Your help is welcome! Let's first test the RawTurtle class.

Yes, I do. However, I prefer not to be assigned, as I'm unsure when I might be available to do this.

I realized that python -m test doesn't run doctest against the turtle module. Is there some reason for that? Or was it just forgotten?

[picnixz]

Doesn't it need -ugui resource? if this still doesn't run the doctests, then maybe it's a more general issue where we don't run doctests in the code at all.

Doens't work.

if this still doesn't run the doctests, then maybe it's a more general issue where we don't run doctests in the code at all.

I found it working for the enum module, for instance.
