我已经阅读过它可能与sqlite3有关的地方,但我的谷歌搜索没有产生任何帮助.以下是错误示例：
https://travis-ci.org/NullVoxPopuli/aeonvera/jobs/61047991
它似乎随机发生 – 无论是在我的机器上还是在travis上.所以我最终不得不重新运行rspec直到它通过 – 这非常烦人,因为我的测试套件需要几分钟才能运行.
这是怎么造成的？我该如何预防？与你的CI积极合作以重新运行规范直到它通过为止是有点愚蠢的.
我正在使用sqlite3在内存中运行我的所有规格 – 这是一个很好的速度奖金,也帮助我确保我没有做任何特定于数据库的查询(我的生产应用程序使用pgsql)
如果有人好奇,这里是我的回购链接：https://github.com/NullVoxPopuli/aeonvera
UPDATE
这不是特定于sqlite3的 – 当使用postgresql时也会发生这种情况.

解决方法@H_502_22@
你可以尝试退回你的git历史,直到你有一个稳定的状态.并从那里引入变化来隔离“坏”变化.
此外,即使在测试中,也应该避免在sqlite3上使用.测试应尽可能接近生产.
