Simple Loops

Instructions

1. Fork and clone this lab. Then, open it in sublime and run the test suite with the learn or rspec command.
2. This lab requires you to write a series of methods that use the different looping constructs we've covered in this unit. Read the comments in simple_looping.rb. This is the file where you'll be coding your solution. The comments will help you to solve the lab and get the tests passing.
3. Each method takes in an argument of an integer. If you call one of the methods with an argument of 4, your method should loop and puts out a phrase 4 times. If you call the same method with an argument of 10, your method should loop and puts out that phrase 10 times.
4. As you move through the lab, think about the differences between the looping constructs you're utilizing. What are some advantages to using certain constructs? Disadvantages?

RSpec — A Closer Look:

Take a look at your spec/simple_looping_spec.rb file. You'll notice on line 4 that there is a before(:each) do statement. What is this? This is what's called a before hook. What this is doing is taking the code that is inside the before hook's block and executing it at the start of each test (denoted by the it keyword). For example, this:

it "prints out some witty statement from the 1990's" do
  @say_my_name = "Oh snap, Destiny's Child!"
  expect(@say_my_name).to eq("Oh snap, Destiny's Child!")
end

can be accomplished by this:

before(:each) do
  @say_my_name = "Oh snap, Destiny's Child!"
end

it "prints out some witty statement from the 1990's" do
  expect(@say_my_name).to eq("Oh snap, Destiny's Child!")
end
