This is a showcase that very-long functions may be accepted by max-func-body-length rule if the function is defined as a parameter of a pre-defined function/method, of which name matches /^.*describe.*$/.

Just npm i and npm run lint for your try.

The behaviour could be an expected one, but the pattern mathces to names which do not look like describe, such as xyzdescribexyz for example, and this is not a good idea.
