修复＆amp;底部的原始测试
我有两个模型测试，格式相同但只有一个有效。我是迷你测试或一般测试的新手。我还阅读了mini-test＆amp; amp;的问题列表。只是没有足够的技能或理解来找到适用于所发布的不同问题的修复。
目标：在我的CampplayTest.rb文件中工作.valid?或了解其失败的原因＆amp;我应该在它的位置使用什么（如设计blowmage说.valid？应该用来代替.save！）
编辑：显然这是我的模型 - 不确定这是如何无效 - 请参阅下面的原始错误
此处的测试文件失败......
require 'test_helper'
class CampplayTest < ActiveSupport::TestCase
# Test one missing from pair of ID
test 'invalid - no campaign' do
county = campplay.new(player_id: 1)
refute county.valid?, 'Campplay passed without a name'
end
end
在此处传递测试文件......
require "test_helper"
class County_Test < ActiveSupport::TestCase
def setup
@county = County.create(name: "Example Item")
end
test 'valid county' do
assert @county.valid?, 'county must have name'
end
# Test duplicate
test 'invalid - duplicate county' do
county = County.new(name: "Example Item")
refute county.valid?, 'county passed without a name'
end
end
我试过......

Rails版本 - 情况可能应该修复 - 但我现在正在制作一份清单＆amp;警卫不接受这个版本只是一个调整......
mirv:~/workspace (master) $ cd basicB
mirv:~/workspace/basicB (master) $ ruby -v
ruby 2.3.0p0 (2015-12-25 revision 53290) [x86_64-linux]

To reinstall use:
rvm reinstall ruby-2.3.1
FIX
很简单，它是损坏的文件......
drop_table :campplays rails g model Campplay campaign:references player:references 最终测试文件的副本......
require 'test_helper'
class CampplayTest < ActiveSupport::TestCase
test 'valid Campplay' do
cp = Campplay.new(player_id: "1", campaign_id: "1")
assert cp.valid?, 'Campplay must have player_id'
end
# Test one missing from pair of ID
test 'invalid - no campaign' do
cp = Campplay.new(player_id: 1)
refute cp.valid?, 'Campplay passed without a campaign_id'
end
test 'invalid - no player' do
cp = Campplay.new(campaign_id: 1)
refute cp.valid?, 'Campplay passed without a name'
end
end
我将修复归功于@gaston，因为他花时间在它上面
答案 0 :(得分：0)
1）你应该更新ruby
你的Ruby是：2.3.0（buggy）。建议：升级到2.3.1。
2）错误是大写C：
class CampplayTest < ActiveSupport::TestCase
test 'invalid - no campaign' do
county = Campplay.new(player_id: 1) #you should change county to campplay
refute county.valid?, 'Campplay passed without a name'
end
end
3）但是，测试中存在一些错误。测试将通过，但另一个原因，Campplay需要id：
validates :campaign_id, presence: true
validates :player_id, presence: true
有效将因id而失败，而不是因为名称。你应该添加：
validates :name, presence: true #optional ,length: { minimum: 1 }
4）我建议shoulda-matches
这样做，整个测试将替换为
class CampplayTest < ActiveSupport::TestCase
should validate_presence_of(:name)
should validate_presence_of(:player_id)
should validate_presence_of(:campaign_id)
should belong_to(:campaign)
should belong_to(:player)
end
