Question

我的一些测试要求它们按顺序执行。我在http://www.scala-sbt.org/0.13.0/docs/Detailed-Topics/Testing.html上阅读了有关自定义配置的信息，但我遗漏了一些内容，因为我的配置无法正常运行。

这是：

import sbt._
import Keys._

object SchedulingBackendBuild extends Build {
  lazy val SequentialTest = config("sequentialTest") extend(Test)
  def sequentialTestFilter(name: String): Boolean = {
    println("===seq test filter")
    name endsWith "SeqSpec"
  }
  def unitTestFilter(name: String): Boolean = {
    println("===unit test filter")
    !sequentialTestFilter(name)
  }

  lazy val root = Project(id = "scheduling-backend",
    base = file("."),
    settings = Project.defaultSettings
  ).configs(SequentialTest)
  .settings(inConfig(SequentialTest)(Defaults.testTasks): _*)
  .settings(
      testOptions in Test ++= Seq(Tests.Filter(unitTestFilter)),
      testOptions in SequentialTest ++= Seq(Tests.Filter(sequentialTestFilter))
  )
}

我希望test只执行不以SeqSpec结尾的测试，这是有效的，但是当我尝试执行sequentialTest:test时，不会执行任何测试。我在我的过滤器中添加了println，即使执行sequentialTest:test，我也能看到

===unit test filter
===seq test filter
===seq test filter

所以两个过滤器都被执行了。

当我输入inspect sequentialTest:testOptions时，我正在

[info] Task: scala.collection.Seq[sbt.TestOption]

[info]  */*:testOptions
[info]  test:testOnly::testOptions
[info]  test:test::testOptions
[info]  sequentialTest:test::testOptions

所以对我来说看起来没问题，第22行是testOptions in SequentialTest ++= Seq(Tests.Filter(sequentialTestFilter))

部分答案：如果我将++=运算符（附加到序列）更改为:=（替换序列），一切正常（文档中使用:=运算符）。即使这样，我也想知道为什么++=在这种情况下是不好的选择。
