###Meet the O.O.G.G.s The O.O.G.Gs are the Object Oriented Garden Gnomes. You don't want to mess with them, because they're the meanest, toughest, gnomiest gnomes in town.

We're going to build a Garden Gnome class so that we can make individual instances of Garden Gnomes that can terrorize front lawns around the neighborhood. Open the file garden_gnome.rb and follow these instructions. Run learn after completing each step of the instructions to make sure you're on the right track. Try to get each test to pass!

###Instructions

1. Create a class called GardenGnome.
2. Garden gnomes have names. Add a reader and a writer method for name.
3. Garden gnomes also have ages (They can live to 4000 years, in fact). Add a reader and a writer method for age.
4. Little gnome fact: Some garden gnomes are allergic to gluten. Create an attribute gluten_allergy using a reader and writer method.
5. Everyone gnows that that gnomes are all born evil. As such, create an initialize method which sets @personality = "evil" Create a reader for the personality attribute (but no writer, because once an evil gnome, always an evil gnome).
6. Add an argument to your initialize method called hat_color and then use the argument inside the initialize method to set a gnome's hat color at the moment that it is created (using .new). If the user doesn't give a hat color in the argument, it should default to 'red'. Create a hat_color reader and writer to access this attribute.
7. Gnomes can take many evil actions. One of them is destroying the trees in a garden by chewing them up. Create a method gnaw that, when called, returns the value of "Gnawing on a tree!!!"
8. Create another action method called shout that returns the value of "GNARLY!!!" when called.
9. Create an action called introduce_self that returns the value of "Hello humans, my name is _________, I am _____ years old, and you'll rue the day you crossed me!". Blanks should be filled in with the gnome's name and age.

Passing Tests

Your GardenGnome class will have to built very specifically to pass the tests!

What are these tests I'm speaking of? Why it's a little thing call RSPEC! RSPEC is testing framework, made from Ruby, that is used professionally while building applications. When changes are made or if new features are added to a project, automated tests can be run to ensure that the changes did not cause anything to break. Running automated tests is significantly more efficient than manually checking everything yourself. Also, it's more accurate! Win win.

We are going to get a taste of what it's like develop having to meet the expectations of tests!

Get Started Running Your Tests

First we need to install RSPEC by going to our Terminal and entering: gem install rspec

Then we should run the tests to see what they are expecting! In terminal, enter: rspec spec/garden_gnome_spec.rb (This command is a lot like running a ruby file in termainal, only we use rspec instead and then give it the path to the name of the file.)

Now you'll see a whole mess of code thrown at you and red text glaring at you with all your failures. That's RSPEC for you. Now you goal is to start with the very first item being tested (at the very top of your failure list) and see what it is asking and what it is expecting.

Note: it can also be helpful to go inside the the rspec file and see what the tests are asking there. Be prepared, there is going to be a lot of new and unfamilair syntax. After giving it a good look, it should be more intuitive to navigate through all those expectations!

Getting More In The Gnome

Once you've gotten all the learn tests to pass, practice creating instances of the GardenGnome class by following these instructions:

1. Create a new instance of the GardenGnome class and assign it to the variable gnome1.
2. Create another instance of GardenGnome and set it's name to "Walter the Worst".
3. Create another instance of GardenGnome and set it's name to "James the Jerk" and its age to 3421.
4. Create another instance of GardenGnome and set it's name to "Alfed the Abhorrent" and its age to 579. Set its gluten_allergy attribute to true. (Alfred has terrible allergies.)
