如何從build.sbt指定特定測試

Question

如何從build.sbt文件中指定測試，我只想運行一個測試，並且像sbt docs一樣使用過濾器，但是它對我不起作用，這是我的代碼，我有兩個測試類在我的sbt中，我將test1指定為rub，但是似乎兩個測試同時運行，任何人都知道我應該怎么做？

Test1Demo.scala

import org.scalatest.{FlatSpec, Matchers}

class Test1Demo extends FlatSpec with Matchers{
  "value of x " should " be 9 " in { assert(my.App.x == 9) }
}

Test2Demo.scala

import org.scalatest.{FlatSpec, Matchers}

class Test2Demo extends FlatSpec with Matchers{
  "value of y " should " be 8 " in { assert(my.App2.y == 8) }
}

build.sbt

version := "0.1"

scalaVersion := "2.12.8"

libraryDependencies += "org.scalatest" %% "scalatest" % "3.0.5" % Test

testOptions in Test := Seq(Tests.Filter(s => s.startsWith("Test1")))

輸出 ：

如果要從Test1Demo運行value of x test的value of x ：

testOnly *Test1Demo -- -z value

此sbt命令將僅運行名稱包含子字符串“ value”的測試。

對於完全匹配而不是子字符串，請使用-t而不是-z 。

注意-- （兩個- ，不是一個）
