scalatest在intellij 13.1中不起作用

Question

null

object Calc {
  def add(a: Int, b: Int) = {
    a + b
  }
}

import org.scalatest.FunSuite

class Calc$Test extends FunSuite {
  test("two number should add") {
    assert(Calc.add(2, 5) == 7)
  }
}

你知道有什么问题吗？我假设这是由简单的配置问题引起的，因为代码已经尽可能简单了。

Answer 1

您显然遇到的一个问题是，您要求的是为Scala2.11编译的scalatest版本，但您说您使用的是Scala2.10。在build.sbt中需要“Scalatest2.10”而不是“Scalatest2.11”。使用

libraryDependencies += "org.scalatest" % "scalatest_2.10" % "2.2.1" % "test"

或者甚至

libraryDependencies += "org.scalatest" %% "scalatest" % "2.2.1" % "test"

要自动获取Scala版本（请注意将其更改为双个百分比：%%。）
