Added new tests and created a Mocking 'Telegram Response' class

Looking for feedback on this.

Have never done testing before, so I'm sure there can be many improvements or better ways to do things. Please show me how! :)

Looks good to me 👍

Good job :) Moving to a different class seems cleaner.
Maybe, I'd just rename TGMocks to something like MocksProvider, or Mocker, what you think ?
And perhaps it should be inside the Mocks dir ?

Mocker sounds good 👍

@antoniomadonna Yes, I'll move the class. Good idea.

I toyed around with the name for ages, but here's what I thought.

MocksProvider was too long, especially when we will be typing it alot.
Mocker....was there any risk of this being mistook for the Mockery Library?
ResponseGenerator - Too long
Generator - too ambiguous.
APIMock - ??

If everyone thinks Mocker is good I'll change it.
