[英]Rails - FactoryGirl - test models [validation]
I would like to test my models but all informations that I could find seems to be outdated. 我想测试我的模型,但是我能找到的所有信息似乎都已过时。 My goal is to test each individual validation. 我的目标是测试每个单独的验证。 My model: 我的模特:
class Author < ActiveRecord::Base
has_and_belongs_to_many :books
before_save :capitalize_names
validates :name, :surname, presence: true, length: { minimum: 3 },
format: { with: /[a-zA-Z]/ }
private
def capitalize_names
self.name.capitalize!
self.surname.capitalize!
end
end
and my factorygirl define: 和我的factorygirl定义:
FactoryGirl.define do
factory :author do |f|
f.name { Faker::Name.first_name }
f.surname { Faker::Name.last_name }
end
end
So now, I want to test whether name is not shorter than 3 characters. 所以现在,我要测试名称是否不少于3个字符。
My context: 我的情况:
context 'when first name is too short' do
it { expect( FactoryGirl.build(:author, name: 'Le')).to
be_falsey }
end
I know it's invalid because of [FactoryGirl.build(:author, name: 'Le')] returns hash instead of boolean value. 我知道它是无效的,因为[FactoryGirl.build(:author,name:'Le')]返回哈希值而不是布尔值。 So now, how should I test it? 那么现在,我应该如何测试呢? What matcher should I use? 我应该使用什么匹配器?
[SOLVED] [解决了]
Use be_valid instead of be_falsey. 使用be_valid而不是be_falsey。 Now it should look like : 现在应该看起来像:
context 'when first name is too short' do
it { expect( FactoryGirl.build(:author, name: 'Le')).not_to
be_valid }
end
