定義工廠
如果你有一個帶有名稱和電子郵件屬性的 ActiveRecord User 類,你可以通過使 FactoryGirl 猜測它來為它建立一個工廠:
placeholderCopyFactoryGirl.define do
factory :user do # it will guess the User class
name "John"
email "john@example.com"
end
end
或者你可以明確甚至更改其名稱:
placeholderCopyFactoryGirl.define do
factory :user_jack, class: User do
name "Jack"
email "jack@example.com"
end
end
然後在你的規範中,你可以使用 FactoryGirl 的方法,如下所示:
placeholderCopy# To create a non saved instance of the User class filled with John's data
build(:user)
# and to create a non saved instance of the User class filled with Jack's data
build(:user_jack)
最常見的方法是:
placeholderCopy# Build returns a non saved instance
user = build(:user)
# Create returns a saved instance
user = create(:user)
# Attributes_for returns a hash of the attributes used to build an instance
attrs = attributes_for(:user)
