Java TDD Challenge

This is a small exercise to practice TDD in Java. To participate, please follow these simple steps:

1) Fork this repository.

• You need to be logged-in with your Github account.
• Click the "Fork" button in the upper right!
• In your repository's settings, enable issue tracking.

2) Set-up Travis CI for your fork

• Log-in to Travis CI and
• Enable automatic builds for your exercise repository.

3) Dive into the code

• Clone the repository on your computer!
• You are not allowed to modify any code files
  • except in the package phones.impl
  • and in the test folder,
  • or if otherwise noted.
• Try to get all tests green!
  • Preferably, not by deleting the tests. There is no one to cheat but yourself!

4) Commit and push

• When you are done, push your changes.
• Travis CI will now try to build your project.

5) Check your inbox

• You will be notified of problems via Github issues.
• While you wait, see if your code can use some refactorings.

6) Repeat steps 3 to 5 until no more issues are posted

• The end is a bit anti-climatic. Sorry for that!
