 ## Read the Tests
-We know that you do not have much experience with testing, so that is why it is very important for you to read the instructions in this and following labs.  Still, reading the tests will provide you a lot of guidance to complete the lab.  Let's take a look at the first test together:

-Ok so all of the fancy `describe` words are just there to organize the requirements, and provide a mechanism for what each function should do.  By reading the text inside of the `describe` words, we can see that there is some function that should give customers a free sample, where the first 400 feet are free.  Then in the next line we see a function called `scuberGreetingForFeet` being executed with `199` passed through as an argument to the function.  Executing the `scuberGreetingForFeet` function with the argument returns `"This one is on me!"`.

-If we run the tests by running `learn-test` we see that `scuberGreetingForFeet` is not defined.  We can fix this by writing a function `scuberGreetingForFeet` in the index.js file.  The big insight is that the tests in the indexTest.js file are calling the functions that we write the index.js file.  These tests pass arguments to our function.  When this test passes an argument of `199` to our function, the `scuberGreetingForFeet` function should return `"This one is on me!"`.  That makes sense, considering the text in the `describe` and `it` functions say that the first 400 feet should be free.  That `199` must be indicating the distance in feet of the requested ride.

-So reading tests are essentially like reading the instructions.  It's something, we may have avoided for much of our lives, but when it comes to programming, tests fill in the picture of the goal we are trying to accomplish.  They run mini-experiments on our code and help us better understand our code and the problem we are solving.
