为什么测试期间我的ruby崩溃/ segfault？
我读过的地方可能与sqlite3有关，但是我的谷歌搜索没有任何帮助。 这里是一个错误的例子：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。
这是如何造成的？ 我如何防止它？ 有必要积极地与你的CI进行交流，以重新运行规范，直到它通过。
我使用sqlite3在内存中运行我的所有规格 - 这是一个很好的速度奖金，并且还帮助我确保没有执行任何特定于数据库的查询（我的生产应用程序使用pgsql）
这里有一个链接到我的回购，如果有人很好奇：https：//github.com/NullVoxPopuli/aeonvera
UPDATE
这不是sqlite3特有的 - 它也发生在使用postgresql时。

你可以尝试退回你的git历史，直到你有一个稳定的状态。 并从那里引入更改以隔离“不良”变化。
另外，即使在测试中，也应该避免使用sqlite3。 测试应尽可能接近生产。
