使用rspec和factory_girl，在哪里存储需要共享的硬编码值？

发布于 2024-10-20 21:25:01 字数 151 浏览 1 评论 0原文

我在rails 3应用程序中使用rspec和factory_girl。

我现在正在 /spec/factories 中设置我的工厂，只是好奇我应该在哪里放置其他工厂需要引用的属性哈希或硬编码 ID？

我对此很陌生，因此正在寻求有关如何正确执行此操作的指导。

Factory Girl 希望您使用关联和序列，而不是硬编码的 ID。以下示例为您提供了在 rdoc 中搜索内容的核心以及使用工厂的基础知识。您可能应该远离任何硬编码的 ID，因为它会导致脆弱的测试，这些测试在某些随机情况下不起作用（这需要您半天的时间才能弄清楚）。

#the basics
Factory.define(:post) do |f|
  f.association :author
end

Factory.define(:comment) do |f|
  f.text "boo"
end

# callbacks
Factory.define :article_with_comment, :parent => :article do |article|
  article.after_create { |a| Factory(:comment, :article => a) }
end

p = Factory(:article_with_comment)
p.comments.first.text # => "boo"
p.author #=> yep, used the association to make it

#sequences
Factory.define(:author) do |f|
  f.email { Factory.next(:email) }
end

# and override the default behavior
p = Factory(:post, :title => 'new post', :author => Factory(:author, :email => "[email protected]") )
p.author.email # => [email protected]

...deep inside a test

p = Post.find_by_title('new post') # => this is the most basic way to get around id's

Factory Girl is expecting that you use associations and sequences, not hard coded id's. the following examples give you the core of what to search for in the rdoc and basics for using the factories. You should probably stay away from any hard coded id's because it will lead to brittle tests that don't work on some random occasion (which takes you half a day to get to the bottom of).

#the basics
Factory.define(:post) do |f|
  f.association :author
end

Factory.define(:comment) do |f|
  f.text "boo"
end

# callbacks
Factory.define :article_with_comment, :parent => :article do |article|
  article.after_create { |a| Factory(:comment, :article => a) }
end

p = Factory(:article_with_comment)
p.comments.first.text # => "boo"
p.author #=> yep, used the association to make it

#sequences
Factory.define(:author) do |f|
  f.email { Factory.next(:email) }
end

# and override the default behavior
p = Factory(:post, :title => 'new post', :author => Factory(:author, :email => "[email protected]") )
p.author.email # => [email protected]

...deep inside a test

p = Post.find_by_title('new post') # => this is the most basic way to get around id's
