 ## Writing Tests for Legacy Code
 
 It is likely you already have some code that you will be using as a foundation to add additional functionality. Before you add more features you should take time to write test suites that cover the existing code. Although this can take some time it is something you should always take time to do if you are to create a robust piece of software.
