Michael Hartl的Rails教程第12章 - 所有54项测试都失败了......？

Question

所以我参加了Michael Hartl的Rails教程,第12章,列出了12.7.

我已经写了一些测试,但是所有的54个测试最终都出现了错误.前几个是:

ERROR["test_should_require_a_followed_id", RelationshipTest, 0.686335129]

继续......

这是我的relationship_test.rb:

require 'test_helper'

class RelationshipTest < ActiveSupport::TestCase

  def setup
    @relationship = Relationship.new(follower_id: 1, followed_id: 2)
  end

  test "should be valid" do
    assert @relationship.valid?
  end

  test "should require a follower_id" do
    @relationship.follower_id = nil
    assert_not @relationship.valid?
  end

  test "should require a followed_id" do
    @relationship.followed_id = nil
    assert_not @relationship.valid?
  end
end

我怀疑在relationship_test.rb中可能有什么问题,但我甚至不知道从哪里开始所有这些错误.有人能指出我正确的方向吗？谢谢.

Answer 1

我已经解决了.

我relationships.yml有:

one:
   follower_id: 1
   followed_id: 1

 two:
   follower_id: 1
   followed_id: 1

这导致测试失败.我已将它们评论出来,并且有0个错误,但有一个失败.
