How to write unit test before the class code?

I am trying to get into the habit of writing a unit test before the actual class. What are some pointers the stack overflow community can give me along with any useful resources.

Thank You

  • The idea behind writing the test first is that you know what the code is going to do before you write it. So, you make a list of what you want it to do, and how you want each feature to be used. Then, you write a test for each feature (feel free to write more than one, or how ever many it takes to test the functionality of the object.)

    Now, you have your framework for your class. Your first goal should be to make the test compile by adding all the methods used in the class. Then make the test pass by implementing the methods correctly.

    Boom - Test Driven Development goes on your resume! :-)
