CodeKata-PasswordVerifier

Sample project to train TDD skills by excercizing refactoring.

Task

Create a Password verifications class called “PasswordVerifier” implementing “IPasswordVerifier” interface.

1. Add the following verifications to a master function called “Verify()”

   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.iv is not true.
4. Assume Each verification takes 1 second to complete. How would you solve items 2 and 3 so tests can run faster?
