Test Diagnostics

1. Open a folder in VS Code
2. Add a file named email.py to the root directory of the workspace folder
3. Open the email.py file and verify the presence of a diagnostic message indicating this file could interfere with execution of kernels.
4. Verify the same diagnostic message appears in the file explorer against the file name.
5. Use the problems panel to :
   • Verify the Learn more link works(click on Learn more link)
   • Verify the code action Ignore warning for email will remove these warning messages
6. Repeat the above steps with another file named random.py and verify you get the same messages
7. This time enable/disable this feature using the setting

"jupyter.diagnostics.reservedPythonNames.enabled": false,

8. Add a custom glob pattern to ensure files defined in the glob pattern do not end up with warnings:

"jupyter.diagnostics.reservedPythonNames.exclude": [defaults...]

9. If you have Python installed, then open a Python environment in VS Code and verify you do not get warnings for files in the site-packages folder
