The referenced test is trying to overwrite a color value in the theme from '#000' to '#FFF' to render it to the widget UI. It fails because the method of overwriting a theme variable doesn't seem to work anymore.
The content of renderResult.baseElement.innerHTML is:
<div><div class="widget-show-unit-tests jimu-widget"><p>This widget shows how to unit test a widget.</p><div>Widget label:</div><div>Theme variable:#000</div><button>Click me</button><div>Count:0</div><button>Query features</button><div><div>Query Result count:</div></div></div></div>
As you can see, '#000' is still contained in the widget UI.
The test ouput is:
` test show-unit-tests widget › test theme variable
expect(received).toBeInTheDocument()
received value must be an HTMLElement or an SVGElement.
Received has value: null`
