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.
