PasswordManagerKata

For Java run:

  1. javac PasswordManager.java
  2. java PasswordManager

This is an exersize in making a change to a production-like "Big ball of mud" by "making the change safe, then making the change easy, then making the easy change"

  1. Create a Golden Master WITHOUT CHANGING ANY CODE (make it safe)
  2. Make the requested change by: a. Dependency breaking: safely breaking out the aspect we are interested in from the ball of mud (make it safe) b. Get under test: write unit tests to capture the behaviour of that aspect (make it safe) c. Refactor to make clear: refactor so that the intent of that aspect is clear (make it easy) d. Add a failing test for the new behaviour (make it easy) e. Add the change (easy change)

Your product owner hands you the following prioritised backlog:

  2. We need stronger hashing algo for new users
  3. Allow multi language support
  4. Forgot password: Can we add ability to get a hint
