如何在rspec中打印let符号的值？

Question

如果我的规格中有以下行

  include Rack::Test::Methods

  let(:competition_date) { Date.today+10.days }

如何在rspec中打印competition_date符号的值？

Answer 1

在RSpec中，let中定义的变量可在before和it块中访问。所有内容都必须包含在describe块中，例如：

describe "let variables" do
  let(:competition_date) { Date.today+10.days }
  it "should be accessible within it blocks" do
    expect(competition_date).to be == Date.today+10.days
    puts competition_date
  end
end
