The best way to learn TDD is by just doing it. I suggest you build a new project using TDD. This means don't write any non-testing code unless you have a failing test.

It will make you think about writing tests: I want to write this code, how do I write a test for it so I can write it.

It will show you the layered nature of testing. Instead of want a name that is required and can't contain numbers. you'll first test setting and reading a name, test requiring the name, test it shouldn't contain numbers, than think if it has more constraints and test those.

Remember:

• Write a test before you write the code
• Make sure the test fails! It's important to know you're testing logic is correct
• Before writing the next test make sure all tests succeed
• You can always clean up your code, if the tests keep working you didn't change the design
