Online Ruby Code Editor for Interviews

Getting Started with Our Ruby Code Editor

Ruby is a dynamic, open-source programming language known for its simplicity and productivity. It has an elegant syntax that is natural to read and easy to write. Ruby is popular for web development, particularly because of the Ruby on Rails framework, which allows developers to create high-performance web applications rapidly.

This environment runs Ruby 2.7.0.

This ruby environment comes with the following installed Libraries:

• RSpec - Behaviour Driven Development for Ruby.
• MiniTest - Provides a complete suite of testing facilities supporting TDD, BDD, mocking, and benchmarking.
• HTTParty - Makes HTTP fun again!
• Faraday - HTTP/REST API client library.
• Excon - Usable, fast, simple HTTP 1.1 client.

This REPL environment is provided via Pry - A powerful alternative to the standard IRB shell for Ruby.

Here is a simple example of how you can use MiniTest here:

require 'minitest/autorun'

class FizzBuzz
  def call(n)
    return 'FizzBuzz' if n % 15 == 0
    return 'Fizz' if n % 3 == 0
    return 'Buzz' if n % 5 == 0
    n
  end
end

describe FizzBuzz do
  it 'must return Fizz for multiples of 3' do
    _(FizzBuzz.new.call(3)).must_equal 'Fizz'
  end

  it 'must return the number for non-multiples of 3 or 5' do
    _(FizzBuzz.new.call(7)).must_equal 7
  end
end
