You know that it's important to test your code, but you're not sure how to get started. Just because you didn't write your tests first doesn't mean it's too late to add tests. We'll look at strategies for adding coded testing into your existing applications and what kinds of modifications you may need to make to your code to make it more testable.

You will learn:

• How to improve your Software Development Lifecycle by starting to add developer unit tests to your existing applications.
• Discover changes you may need to make to your code base to inject dependencies to support testability.
• The differences between unit testing, integration testing, and functional testing and when to use each.
