The Extract RSpec 'let' refactoring allows you to extract a specified code fragment into a memoized helper method. To do this, perform the following steps:

Example

Before

describe "GetTime" do
    it "gets the same time" do
        puts Time.now
        sleep(3)
        puts Time.now
    end
end

After

describe "GetTime" do
    let(:current_time) { Time.now }
    it "gets the same time" do
        puts current_time
        sleep(3)
        puts current_time
    end
end
