How to mock window.matchMedia - Test environment Jest throws "TypeError: window.matchMedia is not a function"

[Wezea]

Hi there :-)

tinynce-react is great and doing its thing. In the browser we do not have any issues. However, running our tests causes all test suites to fail. Jest is throwing this exception:

TypeError: window.matchMedia is not a function

We have followed the Jest manual and added a mock for window.matchMedia but still this is not working.

How could we get access to the window object within the TinyMCE instance and mock window.matchMedia?

What I can't wrap my head around: Even tests without any TinyMCE dependency are crashing with this exception.

We are running:

tinymce: 5.10.5
@tinymce/tinymce-react: 3.14.0

We would highly appreciate some help, as all our tests are currently failing.
