Thanks for opening this issue!
I'll look into it this afternoon and let you know!

Thank you so much! If there is any additional information I can help provide please let me know. I did notice that the types included with Jest seem to be the main culprit which is causing the compile errors. Not sure why they don't include addMatchers here.

Indeed. It seems jest only ships part of Jasmine's API.
I looked at Jasmine types, addMatchers is correctly defined here: https://github.com/DefinitelyTyped/DefinitelyTyped/blob/master/types/jasmine/index.d.ts#L391
