Sbt不会运行ScalaTest测试

Question

我正在运行Scala 2.10.3和sbt 0.13.5 ，并且松散地关注Twitter的scala sbt教程我遇到了一个小问题。 单元测试根本不会运行。

我的build.sbt：

libraryDependencies += "org.scalatest" % "scalatest_2.10" % "2.1.7" % "test"

我的考试班：

package com.twitter.sample

import collection.mutable.Stack
import org.scalatest._

object SimpleParserSpec extends FlatSpec with Matchers {
  "SimpleParser" should "work with basic tweet" in {
    val parser = new SimpleParser
    val tweet = """{"id":1, "text":"foo"}"""
    parser.parse(tweet) match {
      case Some(parsed) => {
        parsed.text should be ("foo")
        parsed.id should be (1)
      }
      case _ => fail("didn't parse tweet")
    }
  }
}

这是在项目文件夹中运行sbt test的输出：

[info] Loading global plugins from C:\Users\Slench\.sbt\0.13\plugins
[info] Set current project to twitter-sbt (in build file:/C:/Users/Slench/Desktop/twitter-sbt/)
[info] Run completed in 36 milliseconds.
[info] Total number of tests run: 0

[info] No tests were executed.
[success] Total time: 0 s, completed 05-06-2014 20:19:11

我不确定出了什么问题，所有文件都在正确的文件夹中，一切都编译没有错误或警告，但它不会运行我的测试...任何帮助？

将SimpleParserSpec从object更改为class ，它应该可以工作。

特别是改变线

//bad
object SimpleParserSpec extends FlatSpec with Matchers

至

//good
class SimpleParserSpec extends FlatSpec with Matchers
