我正在尝试使用factory_girl创建一个“用户”工厂(使用RSpec),但似乎它并没有以事务方式运行,显然由于测试数据库中之前测试的残留数据而失败了。
Factory.define :user do |user|
user.name "Joe Blow"
user.email "joe@blow.com"
user.password 'password'
user.password_confirmation 'password'
end
@user = Factory.create(:user)
运行第一组测试是可以的:
spec spec/
...
Finished in 2.758806 seconds
60 examples, 0 failures, 11 pending
一切都很好,和预期的一样,不过需要再次运行测试:
spec spec/

修复尝试 - 使用Factory.sequence
由于我的email字段有一个唯一性约束,我尝试使用factory_girl的sequence方法来解决这个问题:
Factory.define :user do |user|
user.name "Joe Blow"
user.sequence(:email) {|n| "joe#{n}@blow.com" }
user.password 'password'
user.password_confirmation 'password'
end
我随后运行了
rake db:test:prepare
spec spec/
.. # running the tests once executes fine
spec spec/
.. # running them the second time produces the same set of errors as before
用户似乎仍然保留在数据库中
如果我查看/db/test.sqlite3数据库,似乎测试用户的行没有在测试之间从数据库中回滚。我认为这些测试应该是事务性的,但是对我来说似乎不是这样。
这就解释了为什么第一次测试运行正确(并且如果我清除数据库),但第二次失败。
有人能解释一下我应该更改什么以确保测试以事务方式运行吗?
