使用Specs2测试json数据

我添加了(在built.sbt中)matcher-extra: -

 "org.specs2"              %% "specs2"            % "2.3.4"                  % "test",
"org.specs2"               % "specs2-matcher-extra_2.10" % "2.3-scalaz-7.1.0-M3",

("/"符号未解析)

我对Json的示例测试用例如下所示: -

package specs.model
import org.specs2.mutable.Specification
import org.specs2.matcher.JsonMatchers

class Json extends Specification with JsonMatchers {

"Json Matcher" should {
"1st field" in {
  val json = """{"name":"sagar"}"""
  json must  /("name" -> "sagar")
}
"2nd field" in {
  val json = """{"id":1}"""
  json must  /("id" -> 1.0)
}
}
}

ERRORMSG: -
