 # Project Summary
 
-In this project, we'll learn about TTD ( test driven development ). Using Jest, we'll create Unit Tests for methods and properties inside of `cart.js`. After the Unit Tests are created, we'll create the solution for `cart.js` to make all the Unit Tests pass. The TTD approach can lead to more confidence that the code you create meets all technical requirements.

-When we require `cart.js`, we gain access to all of its exported methods and properties. You can view how many methods and properties there are by opening `cart.js`. We can group the test cases specifically for the two cart properties into a group called `Cart Properties:` and we can group the test caes specifically for the three methods into a group called `Cart Methods:`. In Jest, you can create test groups by using the `describe` keyword. The first `argument` for `describe` is the name of the group and the second `argument` is a callback function that holds all the test cases.

 Let's move on to our last method: `checkout`. This method should be pretty easy to test. All we need to do here is add a random number of cars to our cart and then call the `checkout` method. We can then `expect` `cart` equals an empty array and we can then `expect` `total` equals `0`.
