Question

问题：我需要做哪些修改，以便我在命令行中的测试结果将会整齐，而不是显示我的print语句。

我有这堂课：

class Hello
  attr_accessor :name

  def say
    print "What is your name? "
    @name = gets.chomp
  end
end

如果它将用户输入名称存储在@name。

中，我想这样做

我目前的测试工作：

it "stores the user's name to a `name` instance variable" do
  greeting = Hello.new

  allow(greeting).to receive(:gets).and_return("Brian")
  greeting.say

  expect(greeting.name).to eq "Brian"
end

但它会污染我的输出，也需要我按回车。

为了在运行规范时使测试结果无法在命令行中显示，您可以存根$stdout的输出流：

before do
  allow($stdout).to receive(:write)
end

为了使用存根输入发送返回字符，您需要为其提供换行符：

allow(greeting).to receive(:gets).and_return("Brian\n")

Rspec 3存根用户输入
