为什么sbt会说“糟糕的符号引用……”用ScalaTest进行测试?

导读:我开始在sbt上使用 ScalaTest. build.sbt如下: name := "MySpecSample"version := "1.0"libraryDependencies += "org.scalatest" % "scalatest_2.11" % "2.2.0" % "test"scalaVersion := "2.10.3" 初始测试代码在这里.此测试代码单独运行,没有主要组件代码.
我开始在sbt上使用
ScalaTest. build.sbt如下:
name := "MySpecSample" version := "1.0" libraryDependencies += "org.scalatest" % "scalatest_2.11" % "2.2.0" % "test" scalaVersion := "2.10.3" 初始测试代码在这里.此测试代码单独运行,没有主要组件代码. import collection.mutable.Stack import org.scalatest._ class ExampleSpec extends FlatSpec with Matchers { "A Stack" should "pop values in last-in-first-out order" in { val stack = new Stack[Int] stack.push(1) stack.push(2) stack.pop() should be (2) stack.pop() should be (1) } it should "throw NoSuchElementException if an empty stack is popped" in { val emptyStack = new Stack[Int] a [NoSuchElementException] should be thrownBy { emptyStack.pop() } } } 我是根据Official quick start写的. > test [info] Compiling 1 Scala source to /Users/kaisasak/untitled/target/scala-2.10/test-classes...

在build.sbt中,使用以下命令将Scala的版本设置为2.10.3:
scalaVersion := "2.10.3" 但是,ScalaTest依赖项显式使用Scala 2.11(请注意_2.11部分): "org.scalatest" % "scalatest_2.11" % "2.2.0" % "test" 您必须为两者使用相同的主要scala版本. 使用sbt,您可以使用%%而不是%来确保这一点,如下所示: "org.scalatest" %% "scalatest" % "2.2.0" % "test" (编辑:李大同) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
