如何从rspec测试中调用方法

Question

我正在学习Ruby和TDD(rspec).

我写了以下测试:

describe is_eligible do
  it "returns true if the passed in string is not part of a list" do
    result = is_eligible("abc")
    result.should eq(false)
  end
end

它正在测试以下代码:

def is_eligible(team_name)
  array = Array.new
  array << "abc" << "def" << "ghi"
  if array.include?(team_name)
    return false
  else
    return true
  end
end

我收到以下错误,无法找出原因.

*/Users/joel.dehlin/top32/lib/ineligible_teams.rb:6:in`is_eligible':错误的参数个数(0表示1)(ArgumentError)*

任何帮助表示赞赏!

问题是该describe方法需要一个字符串或可以计算为字符串的东西.如果你说"is_eligible"没有引号,它实际上会尝试调用该方法,你会得到错误.

describe "is_eligible" do
  it "returns true if the passed in string is not part of a list" do
    result = is_eligible("abc")
    result.should eq(false)
  end
end
