RSpec use_transactional_fixtures = false无效

在我的spec_helper.rb文件中设置use_transactional_fixtures = false，但是当我查看测试日志的输出时，似乎仍在使用事务？为什么会这样，我该如何消除交易呢？

1 个答案:

答案 0 :(得分：1)

当您设置config.use_transactional_fixtures = false时，您告诉RSpec每次启动新示例时都不打扰清理数据库。有时我将其设置为false，因为我改为使用database_cleaner（GitHub）来处理它。

因此，根据你的日志，我相信RSpec正在做它应该做的事情。

您可以在RSpec manual

中了解此设置
