Regarding testing

First thing is that I don't see testing here, and that is the reason of opening the issue.

I don't know too much about testing frameworks in javasciprt so I would probably make a bad call, but other than that it should be reasonibly easy to write some tests about the window object complying with the NIP-07 spec.

So have anybody gave any thoughts about the testing framework (something along the lines of junit or pytest)
