Scalatest 在 Intellij 13.1 中不起作用

Question

我似乎无法让 Intellij 13.1 运行我的测试。我创建了一个简单的项目来尝试隔离问题，但它也无法在那里工作。这是我的设置:

Intellij 13.1 针对 JDK 1.6(需要使用 Java 库)

SBT 支持的 Scala 2.10 项目

最新的 scalatest (libraryDependencies += "org.scalatest"% "scalatest_2.11"% "2.2.1"% "test")

这是苏特:

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

这是测试:

import org.scalatest.FunSuite

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

这是我得到的错误:

知道可能是什么问题吗？我认为这是由一个简单的配置问题引起的，因为代码尽可能简单。

Answer 1

您显然遇到的一个问题是，您要求使用为 Scala 2.11 编译的 scalatest 版本，但您说您使用的是 Scala 2.10。您需要在 build.sbt 中使用“scalatest_2.10”而不是“scalatest_2.11”。用

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

或者甚至

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

自动获取您的 Scala 版本(注意更改为双百分比:%%。)
