Kata

Instructions mention it should return "Invalid date" but the tests are testing for "Invalid date!" (in those cases)

Tests are still quite weak and doesn't test the requirement strictly.

Also, where are the random tests?

Interesting kata. Maybe it could be streamlined in a more straightforward "write a dateFromString function".

Description needs more work

• Year does not have to be 4 digits.
• When a date is invalid, it should return "Invalid date!"
• You should say what the general format is: dd[spaces][-.][spaces]mm[spaces][-.][spaces]yy[yy] (obviously put better than that, but these thing should be defined.

Tests should be added:

• You never test for the "." delimiter.

Thanks for comments, i corrected description.

The kata description should be cleaned up. The first line says:

Input: date in format dd-mm-yyy

but it also says:

Day: one or two digits

Month: one or two digits

Year: four digits
