Question

我正在尝试一个简单的HelloWorld示例。这是我的目录结构：

hello
  build.sbt
  main
    scala
      Hello.scala
  test
    scala
      HelloTest.scala

Hello.scala包含sayHello函数，我试图通过HelloTest.scala中的简单测试调用该函数。这是我的build.sbt：

name := "Hello"

organization := "tycon"

scalaVersion := "2.11.2"

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

这是一个不运行任何测试的sbt运行：

$ sbt
[info] Set current project to scala (in build
file:~/git/scala/hello/main/scala/)
> compile
[info] Updating
{file:~/git/scala/hello/main/scala/}scala...

[info] No tests to run for test:test
[success] Total time: 0 s, completed Sep 17, 2014 9:04:03 AM

我尝试了其他答案中的建议：将%%替换为%，将scalatest_2.10替换为scalatest中的libraryDependencies，并将scalaVersion更改为2.10.0 }。他们都没有工作。是的，我reload每次都build.sbt改变了。

我相信我遗漏了一些非常基本的东西。我将不胜感激任何帮助。我是Scala的新手。

编辑：为了完整起见，这里有两个scala文件：

Hello.scala：

trait Hello {
  def sayHello () = {
    println ("Hello, World!")
  }
}

HelloTest：阶：

import org.scalatest.FunSuite

class HelloTest extends FunSuite with Hello {
  test("say hello") {
    sayHello()
  }
}

Edit2：我改变了ajozwik和Gabriele建议的目录结构，但是sbt仍然没有运行测试：

~/git/scala/hello/src/main/scala$ sbt
[info] Set current project to scala (in build
file:~/git/scala/hello/src/main/scala/)
> test
[info] Passed: Total 0, Failed 0, Errors 0, Passed 0
[info] No tests to run for test:test
[success] Total time: 1 s, completed Sep 17, 2014 9:36:24 AM

Answer 1

目录结构应该是

hello
  build.sbt
  src
    main
      scala
        Hello.scala
    test
      scala
        HelloTest.scala

即。你错过了外src目录。

此外，您需要从项目的根目录运行sbt，而不是从子文件夹中运行。

无法在Scala中通过sbt运行测试
