我正在为具有以下约束的录音建立一个模型
class Recording < ActiveRecord::Base
attr_accessible :agent_id, :confirmation, :filepath, :phone, :call_queue_id, :date
belongs_to :call_queue
PHONE_FORMAT = /^[0-9]+$|Unavailable/
validates_presence_of :call_queue_id, :agent_id, :phone, :filepath, :date
validates :phone, format: { with: PHONE_FORMAT }
end
并尝试使用以下规范对其进行测试
describe Recording do
let(:queue) { FactoryGirl.create(:call_queue) }
before { @recording = queue.recordings.build(FactoryGirl.attributes_for(:recording)) }
subject { @recording }
# Stuff omitted...
describe "phone" do
it "should be present" do
@recording.phone = ''
@recording.should_not be_valid
end
context "with a valid format" do
it "should only consist of digits" do
@recording.phone = 'ab4k5s'
@recording.should_not be_valid
end
it "should only match 'Unavailable'" do
@recording.phone = 'Unavailable'
@recording.should be_valid
end
end
end
end
前两个测试通过,但第三个测试失败,结果如下:
Failure/Error: @recording.should be_valid
expected valid? to return true, got false
我用rubular测试了我的正则表达式以确保它正常工作,然后再次使用 irb 来确定。我真的很困惑为什么这会失败。
编辑:
我最终通过更改我before
在 rspec 中的声明使规范通过:
describe Recording do
let(:queue) { FactoryGirl.create(:call_queue) }
before(:each) { @recording = queue.recordings.create(FactoryGirl.attributes_for(:recording) }
# the rest is the same...
在某种程度上,这最终对我来说是有意义的。一切都变得混乱的原因(假返回真,反之亦然)是因为一旦属性使记录无效,我就不能再改变它了吗?好像是这样,我只是想确定一下。
