早該測試格式

Question

我試圖測試模型的屬性與此格式：

# myapp/test/unit/comment_test.rb 
require 'test_helper' 

class CommentTest < ActiveSupport::TestCase 
    should_belong_to :article 

    should_validate_presence_of :name 
    should_validate_presence_of :email 
    should_validate_presence_of :content 
    should_validate_presence_of :article_id 

    should_not_allow_values_for :name, "123", "bob_y", "dave!" 
    should_allow_values_for :name, "Bob", "Joe Smith" 

    should_not_allow_values_for :email, "abc", "!s@abc.com", "a@!d.com", "a@a.c0m" 
    should_allow_values_for :email, "example@example.com", "1a@a.com", "a@2a.net" 
end 


# myapp/app/models/comment.rb 
class Comment < ActiveRecord::Base 
    belongs_to :article 

    validates_presence_of :name 
    validates_presence_of :email 
    validates_presence_of :content 
    validates_presence_of :article_id 

    validates_format_of :name, :with => /\b[\w]+\b/i 
end 

我做了類似的排序在其他模型的驗證，它工作正常，但在這其中我得到這些錯誤：

2) Failure: 
test: Comment should not allow email to be set to "!s@abc.com". (CommentTest) 
[/Library/Ruby/Gems/1.8/gems/thoughtbot-shoulda-2.10.2/lib/shoulda/assertions.rb:67:in `assert_rejects' 
/Library/Ruby/Gems/1.8/gems/thoughtbot-shoulda-2.10.2/lib/shoulda/active_record/macros.rb:139:in `__bind_1276100388_113010' 
/Library/Ruby/Gems/1.8/gems/thoughtbot-shoulda-2.10.2/lib/shoulda/context.rb:351:in `call' 
/Library/Ruby/Gems/1.8/gems/thoughtbot-shoulda-2.10.2/lib/shoulda/context.rb:351:in `test: Comment should not allow email to be set to "!s@abc.com". ']: 
Expected errors when email is set to "!s@abc.com", got errors: name can't be blank (nil)name is invalid (nil)content can't be blank (nil)article_id can't be blank (nil) 

我得到這個每個測試應該使，我使用工廠女孩也如果那件事。

您的評論模型未驗證電子郵件格式。你在做什麼沒有什麼問題，你的測試只是沒有通過，因爲你的代碼不適合測試通過。

添加電子郵件格式的驗證到您的評論類。

validates_format_of :email, :with => /\A([^@\s]+)@((?:[-a-z0-9]+\.)+[a-z]{2,})\Z/i 

然後你的測試應該通過。
