如何从build.sbt指定特定测试

Question

如何从build.sbt文件中指定测试，我只想运行一个测试，并且像sbt docs一样使用过滤器，但是它对我不起作用，这是我的代码，我有两个测试类在我的sbt中，我将test1指定为rub，但是似乎两个测试同时运行，任何人都知道我应该怎么做？

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")))

输出 ：

Answer 1

如果要从Test1Demo运行value of x test的value of x ：

testOnly *Test1Demo -- -z value

此sbt命令将仅运行名称包含子字符串“ value”的测试。

对于完全匹配而不是子字符串，请使用-t而不是-z 。

注意-- （两个- ，不是一个）
