Add a workflow triggering Unit Tests #2

Is there a better way to make sure all examples actually run out of the box?

...\dash-multi-page-app-demos>python multi_page_cache_background_callback/app.py
Traceback (most recent call last):
  File "multi_page_cache_background_callback/app.py", line 39, in <module>
    import diskcache
ModuleNotFoundError: No module named 'diskcache'

...\dash-multi-page-app-demos>python multi_page_flask_login/app.py
Traceback (most recent call last):
  File "multi_page_flask_login/app.py", line 15, in <module>
    from flask_login import login_user, LoginManager, UserMixin, logout_user, current_user
ModuleNotFoundError: No module named 'flask_login'

I'm not eager to test every single example as I'd rather use pipelines in my GitLab account.

Yes, I'm running this on Windows and should traditionally use the path separator '\' but somehow that's no longer a problem since quite a while as is easily seen by running many other examples out there. Indeed,

...\dash-multi-page-app-demos>python multi_page_query_strings/app.py
Dash is running on http://127.0.0.1:8050/

 * Serving Flask app "app" (lazy loading)

@schwabts Great idea - I'd welcome a pull request for that.

Did you install the requirements.txt?

@AnnMarieW my fault, thanks for reminding me of why that file exists ;)

However, doing so I got

...\dash-multi-page-app-demos>python -m venv env_dash-multi-page-app-demos
...\dash-multi-page-app-demos>env_dash-multi-page-app-demos\scripts\activate
(env_dash-multi-page-app-demos) ...\dash-multi-page-app-demos>pip install -r requirements.txt
ERROR: Invalid requirement: 'Flask-Caching=> 2.0.1' (from line 9 of requirements.txt)

Moreover, I'd like to point out that the multi_page_query_strings example ran without any issues before installing requirements.txt.

With the file updated by https://github.com/AnnMarieW/dash-multi-page-app-demos/pull/4 I get

(env_dash-multi-page-app-demos) ...\dash-multi-page-app-demos>pip install -r requirements.txt
Collecting ...

I just don't manage to successfully log in on the login page, anyway. 🤷‍♂️
