测试/test_helper.rb :
ENV["RAILS_ENV"] ||= "test"
require File.expand_path('../../config/environment', __FILE__)
require 'rails/test_help'
require 'database_cleaner'
DatabaseCleaner.strategy = :transaction
DatabaseCleaner.clean_with(:truncation, pre_count: true, reset_ids: true)
class ActiveSupport::TestCase
ActiveRecord::Migration.check_pending!
def setup
DatabaseCleaner.start
end
def teardown
DatabaseCleaner.clean
p '-------- DB Cleaned ---------'
end
end
我的测试单元文件:(test1 和 2 是重复的)
require 'test_helper'
class ItemTest < ActiveSupport::TestCase
test "test1" do
i = Item.create!
p ActiveRecord::Base.connection.execute("SELECT auto_increment FROM information_schema.tables WHERE table_schema = 'tmi_game_test' AND table_name = 'items';").first
assert_equal 1, Item.count
assert_equal 1, i.id
end
test "test2" do
i = Item.create!
p ActiveRecord::Base.connection.execute("SELECT auto_increment FROM information_schema.tables WHERE table_schema = 'tmi_game_test' AND table_name = 'items';").first
assert_equal 1, Item.count
assert_equal 1, i.id
end
end
结果 :
