我是 Michael Hartl 的 Tuby on Rails 教程的新手,我在第 9 章的测试中有几个失败的项目。
运行 RSPEC 测试返回:

end
end
end
这是上面的第 73 行
it { should have_selector('title', text: 'Sign in') }
还有上面的第 78 行
specify { response.should redirect_to(signin_path) }
有什么想法吗?我真的不知道这是什么意思。谢谢 Si。
最佳答案
你在第 50 行
let(:user) { FactoryGirl.create(:user) }
但是,当您到达第 73 行时,:user 不再可用,因为您关闭了在第 68 行中定义了 :user 的 describe block 。在您尝试再次使用它的第 77 行,情况相同。
我的建议是将 let(:user) 移到规范的顶部,这样您只需定义一次,而不是将其包含在整个规范中。如果失败,请在第 71 行再次定义它(describe "in the Users controller"do 之后的行)
潜在的解决方案是在顶部定义 let(:user)..... 所以你只需要定义一次 user 而不是在每个 block 中
require 'spec_helper'
describe "authentication" do
subject { page }
let(:user) { FactoryGirl.create(:user) }
