Have a test failing.
Notice that python reports this as an Error. This shows up in the Problems panel and with a squigle.
This is not the right thing to do. Test errors should not be reported as compile errors.

I am not sure if there is a better alternative to use
fyi @jrieken @luabud

Also we now support rendering emojis so test failures could be rendered a bit better. @jrieken can provide more details.
