RSpec的檢驗「與」說法是真

Question

我有以下RSpec的例子：

describe "with spike" do 
    it "succeeds" do 
    a = double('whatever') 

    a.should_receive(:b).with(true) 

    a.b('not false') 
    end 
end 

我怎樣才能讓with接受任何非false參數？

Answer 1

只要寫一個任意消息處理程序：

describe "with spike" do 
    it "succeeds" do 
    a = double('whatever') 

    a.should_receive(:b) { |x| 
     x.should_not be_false 
    } 

    a.b('not false') 
    end 
end
