- [Instructor] I want to introduce you to the concept of unit testing. If you've never heard of this practice before, it's part of a broader scope of programming practices called Agile development. And in that context, unit testing becomes an integral part of your development process in a practice called test-driven development or TDD. In test-driven development, you develop your code in simple phases. So generally the first thing you do is you create some code or you change some existing code, and then you create a repeatable test.
Now this is in a separate code project. It's an actual code test that actually exercises the code that you write and proves that it works the way that it's supposed to. Visual Studio has a facility that allows you to run these tests and view the results. And from there, based on whether or not your tests pass or fail, you repeat the process, either fixing problems or mistakes that you've made or moving on to the next feature that you're supposed to develop. When you practice test-driven development, your goal is to have 100% coverage.
This means that all exposed methods in your project have unit tests written that exercise them fully. Unit tests can be run from within Visual Studio for developer productivity, or you can automate them as part of a continuous integration process using tools like Jenkins, TeamCity, or Team Foundation Server.
