This is a mocking method suggested in the Jest docs, as it is not implemented in JSDOM yet. It can be used to mock values for the Material UI useMediaQuery
hook if it is used in a tested component.
For issues checkout the documentation: https://jestjs.io/docs/manual-mocks\#mocking-methods-which-are-not-implemented-in-jsdom
If there are any updates from Material UI React on testing useMediaQuery
this mock should be replaced https://mui.com/material-ui/react-use-media-query/\#testing
