RSpec is a popular testing tool for Ruby applications. It allows you to write tests in a simple and expressive way. Below are some basic concepts and usage examples of RSpec.

Install RSpec

First, you need to install RSpec. You can do this by adding it to your Gemfile and running bundle install:

group :development, :test do
  gem 'rspec'
end

Writing Tests

Here's an example of a simple RSpec test:

# spec/example_spec.rb
require 'spec_helper'

describe 'Example' do
  it 'is a valid test' do
    expect(true).to be true
  end
end

In this example, we're testing whether the true value is indeed true.

Running Tests

To run your tests, execute the following command in your terminal:

rspec

This will execute all the tests in the spec directory and provide you with a summary of the results.

Helper Files

RSpec uses a file named spec_helper.rb to set up configuration and helper methods. This file is executed before each test.
