How to get started with test-driven development

Test-driven development is focused on short development iterations

Here is the general process:

1. Add a test - Developer must completely understand the software requirements
   
2. Run all tests- Confirms test harness is functioning and the new test fails (New code has not been written yet)
3. Write some code -This is meant to be the first pass and will likely improve as the tests are performed
4. Run the automated tests
5. Refactor code- Clean it up
