Specs2 无法使用 sbt 找到我的测试

Question

我已经使用简单的 sbt 构建了一个用于 Spec2 测试的简单项目。

package main.specs

import org.specs2._

class QuickStartSpec extends Specification {
  def is = s2"""
    This is my first specification
    it is working                 $ok
    really working!               $ok
                             """
}

这是我的 build.sbt 文件：

name := "QuickStartSpec"

version := "1.0"

scalaVersion := "2.10.1"

libraryDependencies ++= Seq("org.specs2" %% "specs2-core" % "3.6.5" % "test")

scalacOptions in Test ++= Seq("-Yrangepos")

但是当我在 sbt 中运行这个命令时

 testOnly main.specs.QuickStartSpec

我得到了这个：

[info] Updating {file:/Users/nabajeet/workspace/SpecsTest/}specstest...
[info] Resolving org.fusesource.jansi#jansi;1.4 ...
[info] Done updating.
[info] Passed: Total 0, Failed 0, Errors 0, Passed 0
[info] No tests to run for test:testOnly

我正在关注此页面以创建示例： https://etorreborre.github.io/specs2/website/SPECS2-3.6.5/quickstart.html

我无法弄清楚我的测试未检测到的原因。

我在 0.13.8 中的 sbt 版本

通过声明

libraryDependencies ++= Seq("org.specs2" %% "specs2-core" % "3.6.5" % "test")

您将specs2 的范围限制为仅测试源目录中的类。您将无法在生产代码中引用specs2 类（src/main/ 下的所有代码）

在您的评论中，您表示您将规范放在/Users/nabajeet/workspace/SpecsTest/src/main/specs/quickStartSpec.scala

尝试将您的文件移动到 /Users/nabajeet/workspace/SpecsTest/src/test/scala/specs/quickStartSpec.scala

不正确的位置是您指定 SBT 没有拾取它的原因（我有信心说它也无法编译）。

默认情况下，SBT 应用 maven 的 standard directory layout 添加 src/main/scala/ 和 src/test/scala/ 用于 scala 代码。这记录在SBT tutorial

我刚刚创建了一个具有以下布局的项目

.
./built.sbt
./src
./src/test
./src/test/scala
./src/test/scala/QuickStartSpec.scala

build.sbt 包含

name := "QuickStartSpec"

version := "1.0"

scalaVersion := "2.11.4"

libraryDependencies ++= Seq("org.specs2" %% "specs2-core" % "3.6.5" % "test")

scalacOptions in Test ++= Seq("-Yrangepos")

并且 QuickStartSpec.scala 包含

package main.specs

import org.specs2._

class QuickStartSpec extends Specification {
  def is = s2"""
    This is my first specification
    it is working                 $ok
    really working!               $ok
                             """
}

这是我得到的 sbt 输出
