[TYPO3-core] Deliver unit tests in the packaged sources?

[Andy Grunwald [wmdb]]

Really big +1 for this.

As a developer for an agency, who uses heavily TYPO3 in big 
installations, we must create xclasses and patches which affects the 
core in importants parts very often.
Shipping the UnitTests with the normal package would help us, to reduce 
the amount of work to checkout them manually every time ;)

But one part is very important:
Normally, unit tests must not be executed in a live environment.
It must be 100% save, that all other services (e.g. database) are mocked 
correctly.
The unit tests must not be modifies the original tables in a running 
production environment!

Just my 2 cents.
