TDD Kata 3

Create a Password verifications class or function for the purposes of password verification. Verification will fail if any one of the rules mentioned does not pass.

1. Implement the following rules:

   1. - password should be larger than 8 chars

   2. - password should not be null

   3. - password should have one uppercase letter at least

   4. - password should have one lowercase letter at least

   5. - password should have one number at least

    Each one of these should throw an exception with a different message of your choosing

    2. Add feature: Password is OK if at least three of the previous conditions is true

    3. Add feature: password is never OK if item 1.4 is not true.

8. Assume Each verification takes 1 second to complete. How would you solve  items 2 and 3  so tests can run faster?
