Before you can work on or run any of these tests, you need to make sure you install the dependencies. The directions are at the root-level of this repository.
In your terminal, change into the mythical-creatures directory, and run the command npm test mythical-creatures/test/unicorn-test.js. To run other tests, just replace the creature name.
Most of the tests are skipped. When you see it.skip('should be a function', () => { in a test, it means that test has been skipped. They are skipped for a good reason - that way, when you run the test suite for the first time, you don't see tons of errors screaming at you in the terminal.
Unskip each test, one at a time in order, so you can concentrate on making one test pass. Unskip the test by deleting the .skip from the test's first line so it should look more like it('should be a function', () => {. Run the test to see what kind of error you are getting, and then implement the code to make the test pass!
Here is a video that walks through the setup and first mythical creature.

Can you complete implementations of each of the creatures without using if
statements? Think about how removing them affects your code.
Can you add two new creatures to the repository? How about a Hydra? Add unit tests exercising some of the following concepts:
- Initializing constructor with data
- Using methods to change the internal state of an instance
- Using methods to query the internal state of an instance
If you've done the creatures above and feel comfortable with those, try conquering a few more creatures!

Notice, some of the syntax with the tests and files are using newer javascript features introduced in es6, like arrow functions, block-scoped variables, and classes. See if you can start flexing your es6 muscles and write your solutions and tests using the new syntax!
