当 SBT 中的 ScalaTest 测试失败时，我会得到堆栈跟踪。我尝试set traceLevel in Test := -1过 SBT 提示，尝试更改build.sbt文件中的内容等，但似乎没有任何帮助。

我想摆脱的是：

> test
[info] TestWritingFunctions:
[info] - threeSquares examples *** FAILED ***
[info]   scala.NotImplementedError: an implementation is missing
[info]   at scala.Predef$.$qmark$qmark$qmark(Predef.scala:252)
[info]   at TestWritingFunctions$$anonfun$1.apply$mcV$sp(WritingFunctions.scala:17)
[info]   at TestWritingFunctions$$anonfun$1.apply(WritingFunctions.scala:16)
[info]   at TestWritingFunctions$$anonfun$1.apply(WritingFunctions.scala:16)
[info]   at org.scalatest.Transformer$$anonfun$apply$1.apply(Transformer.scala:22)
[info]   at org.scalatest.Transformer$$anonfun$apply$1.apply(Transformer.scala:22)
[info]   at org.scalatest.OutcomeOf$class.outcomeOf(OutcomeOf.scala:85)
[info]   at org.scalatest.OutcomeOf$.outcomeOf(OutcomeOf.scala:104)
[info]   at org.scalatest.Transformer.apply(Transformer.scala:22)
[info]   at org.scalatest.Transformer.apply(Transformer.scala:20)
[info]   ...

正如您所看到的，测试失败了，因为我使用了新的???构造作为占位符，但是由于我知道那里有一个占位符，所以我想要*** FAILED ***一条没有所有 rigamarole 的消息。那可能吗？

You can use "-o..." without F or S (i.e, "-o" or "-oD" would give you no stack traces, but not "-oF", "-oS", or "-oDS" would give you a stack trace). That means you'd be suppressing all stack traces. If you specify no reporters at all, you'll get a "-o", which means no stack traces.

If you like the short stack traces in general, but don't want to see them when a NotImplementedError is thrown by ???, you can override withFixture and change NotImplementedError into pending tests:

import org.scalatest._

trait PendingIfUnimplemented extends SuiteMixin { this: Suite =>

  abstract override def withFixture(test: NoArgTest): Outcome = {
    super.withFixture(test) match {
      case Failed(ex: NotImplementedError) => Pending
      case other => other 
    }
  }
}

This way you'll still get short, long, or no stack traces for regular failures, whatever you chose, but see (pending) for tests that fail because of ???.

（不权威，但由于没有其他人回答：）

我怀疑这traceLevel没有做任何事情，因为堆栈跟踪来自 ScalaTest，而不是来自 sbt。

sbt 确实有一个logLevel相关的设置。尝试这个：

set logLevel in Test := Level.Warn

但请注意，这不仅会抑制堆栈跟踪，还会抑制示例中以 . 开头的所有行[info]。相反，您只会[error]在最后得到这些东西，其中至少包含测试失败的套件的名称。

如果您真的只想抑制堆栈跟踪而不更改任何其他内容，我认为这可能是不可能的。查看http://www.scalatest.org/user_guide/using_the_runner，我看到了使堆栈跟踪更短（-oS）或更长（-oF）的选项，但没有完全省略堆栈跟踪的选项。
