So let's go ahead.
Now, the packages have been imported, so let's go ahead and make a new folder here and let's call
it with the two underscores.
Two underscores and then test and then two underscores again.
And that's sort of a convention, uh, from jest, where you put in the test inside.
So you have all of your tests inside of the test folder here with these underscores.
And then let's go inside of Package.json and set up our test script.
So we say inside the scripts inside test here we write out test chest and then dash dash, watch all.
So that's going to run a test runner, which is going to watch all of the files and update the test
as we are editing our test, which you're going to see how that works in a moment.
