-+ `companyName` - Inside the `test/indexTest`, look inside of the word `describe` where the tests are trying to indicate that this test is describing the `companyName` variable.  The `it` word that comes afterwords, tells us the features of `companyName`.  In the first `it` function call, it says that `it` (companyName) `is set as Scuber`.  In the next line, you can see that the test checks to make sure this occurs by seeing if `companyName` equals `Scuber`.  So this means that you need to go to your `index.js` file and declare a variable named `companyName` and set it equal to `Scuber`.  Once you do that, if `learn-test` is running, you will see the first test in this lab as passing.

 In the next `it` function call, we are still describing `companyName`.  This time, it says it `raises error if the companyName is changed`. The next line of code tests this.  It's ok if some of the code in that line are confusing.  Just know that the code attempts to change `companyName` to a different value, and that this reassignment to throw an error.  So you need to make sure that you are using the correct variable type such that reassigning the variable would throw an error.
