How do I set up RSpec for testing in my Rails application?

To set up RSpec, first add the 'rspec-rails' gem to your Gemfile and run bundle install. Then, run rails generate rspec:install.

What files does the rspec:install command create?

It creates the .rspec file and the spec directory, which includes spec_helper.rb and rails_helper.rb.

Can you show me how to write a simple test?

Sure! Here's a basic example: create a file spec/models/user_spec.rb and add:

require 'rails_helper'

describe User do
  it 'is valid with valid attributes' do
    user = User.new(name: 'Test User')
    expect(user).to be_valid
  end
end

How do I run my tests?

You can run your tests by executing bundle exec rspec in your terminal. This will run all the tests in the spec directory.
