scala - "TestsFailedException"和 "Failed 0, Errors 0"测试如何失败

Question

间歇性地，一些 ScalaTest 测试运行失败，并出现这种矛盾的输出:

...
akka.pattern.AskTimeoutException: Timed out
    at akka.pattern.PromiseActorRef$$anonfun$1.apply$mcV$sp(AskSupport.scala:334)
    at akka.actor.Scheduler$$anon$11.run(Scheduler.scala:118)

    at akka.actor.LightArrayRevolverScheduler$$anon$12.run(Scheduler.scala:363)
    at java.lang.Thread.run(Thread.java:744)

如何防止这些故障？如果测试代码成功，我不希望抛出的异常导致测试运行失败。

Answer 1

ScalaTest 本身不区分错误和失败。不过，Sbt 和 JUnit 以及 specs2 一样。您是否有可能在混合中为不同的测试框架编写测试？具体来说，com.example.Spec 是什么样子的？
