我正在为spec/requests/user_pages_specs运行rspec测试：
require 'spec_helper'
describe "User pages" do
subject { page }
describe "home page" do
before { visit root_path }
it { should have_content('Sign up with Facebook') }
it { should have_title(full_title('')) }
end
describe "profile page" do
let(:user) { FactoryGirl.create(:user) }
before { visit user_path(user.id) }
it { should have_content(user.name) }
it { should have_title(user.name) }
end
end
如您所见，我正在使用 FactoryGirl 创建用户。当我运行相同的命令时（即FactoryGirl.create(:user)) is rails console test --sandbox，用户已正确创建并保存。
然而，当我运行测试时，FactoryGirl 在数据库中创建用户，然后在测试实际运行之前释放它。我可以从 test.log 中看到这一点：
[1m[36mActiveRecord::SchemaMigration Load (0.1ms)[0m [1mSELECT "schema_migrations".* FROM "schema_migrations"[0m
[1m[35m (0.1ms)[0m begin transaction
[1m[36m (0.1ms)[0m [1mSAVEPOINT active_record_1[0m

[1m[36mUser Load (0.1ms)[0m [1mSELECT "users".* FROM "users" WHERE "users"."id" = ? LIMIT 1[0m [["id", "1"]]
为什么会发生这种情况以及如何阻止它在测试之后发布？
