[Feature Request]: Moving example into tests

[jmmshn]

Problem

Currently our coverage is a bit poor and it's going to lead to problems.

I think the testing within the dash ecosystem is good enough that we can convert all the examples into tests and achieve significant coverage with very little new added code.

@mkhorton , @janosh let me know if this makes sense.

Proposed Solution

I'm proposing that we do something like this:

• Move the examples to root level, I'll leave a README there or something.
• Add the examples path to the conftest
• Make test functions like this:

# tests/test_example_apps.py
import pytest
from example_apps.app1 import app as app1
from example_apps.app2 import app as app2

def test_app1(dash_duo):
    # Use the app instance directly
    dash_duo.start_server(app1)

yes, that definitely makes sense! 👍 i remember taking a brief look at doing this as part of #362 but didn't follow through. perhaps worth linking this related PR janosh/pymatviz#164 by @DanielYang59 as well
