How do I mock methods in Ruby for testing?

In Ruby, you can use libraries like RSpec or Mocha to mock methods. Would you like an example?

Yes, please provide an example using RSpec.

Sure! You can use allow(object).to receive(:method_name).and_return(value) to mock a method. Here's a simple example:

class User
  def name
    'John'
  end
end

RSpec.describe User do
  it 'mocks the name method' do
    user = User.new
    allow(user).to receive(:name).and_return('Mocked Name')
    expect(user.name).to eq('Mocked Name')
  end
end

What if I want to verify that a method was called?

You can use expect(object).to have_received(:method_name) after the action that should trigger the method call. Would you like to see a full example?
