[英]Ruby on Rails 2.3.8: How do I set up my unit tests such that when there is an error, I can have all the variables in the current scope printed?
[英]Ruby on Rails 2.3.8: Testing: How do I set up an instance variable to use throughout my tests?
可以說,我擁有一些數據,這些數據在我所有的測試中都存在,直到永遠。 我在setup
創建此數據。 我將數據存儲到@instance_var
。 但是在任何測試中調用@ instance_var.attribute時,都會出現以下錯誤:
RuntimeError: Called id for nil, which would mistakenly be 4 -- if you really wanted the id of nil, use object_id
我知道我的實例變量不為null,因為在設置它之后,我可以在其上執行puts @ instance_var.inspect ...
有任何想法嗎?
編輯:
setup do
user = Factory(:user)
account = Factory(:account)
set_user(user)
set_account(account)
puts "||||||||||||||||||||||||||||||||||||||||||||||" #this proves that the instance vars are not null
puts "| object_test.rb |"
puts "| #{@user.name} "
puts "| #{@account.name} "
puts "||||||||||||||||||||||||||||||||||||||||||||||"
end
測試失敗(出現上述錯誤)
test "for detection of first content with multiple contents" do
object = Factory(:object, :user_id => @user.id, :account_id => @account.id)
... #the rest of this test isn't important, as it is the above line, on @user, where the nil.id error occers
在test_helper.rb中
def set_user(user)
@user = user
end
def set_account(account)
@account = account
end
我真的不認為我需要這兩種方法,因為當我在安裝程序中定義@instance變量時,會得到相同的結果
在test_helper.rb中,為ActiveSupport :: TestCase設置了一些常量:
self.use_transactional_fixtures = true
self.use_instantiated_fixtures = false
fixtures :all
禁用這些功能無濟於事。 =(
你有沒有嘗試過
setup do
@user = Factory(:user)
@account = Factory(:account)
end
通常,如果您在設置塊中設置實例變量,則它們應可用於所有測試。 (您可能對合並范圍有疑問。)
我的解決方案是創建一個共享類shared_test.rb
require 'test_helper'
class SharedTest
def self.initialize_testing_data
self.reset_the_database
self.set_up_user_and_account
# make sure our user and account got created
puts "|||||||||||||||||||||||||||||||||||||||||||||"
puts "| The user and account "
puts "| we'll be testing with:"
puts "| #{@user.name}"
puts "| #{@user.account.name}"
puts "|||||||||||||||||||||||||||||||||||||||||||||"
end
def self.reset_the_database
#clear the database and reset it
call_rake("db:test:prepare")
call_rake("db:bootstrap RAILS_ENV=test")
end
def self.set_up_user_and_account
#set up our user for doing all our tests (this person is very busy)
@user = Factory(:user)
@account = Factory(:account)
@user.account = @account
@user.save
end
end
因此,在需要用戶和帳戶在所有測試之間保持一致的每個測試文件的頂部,您只需執行
require 'shared_test.rb'
和方法稱為
SharedTest.initialize_testing_data
