Question

我无法编译简单的specs2 hello world示例：

import org.junit.runner.RunWith
import org.specs2.Specification
import org.specs2.runner.JUnitRunner

import org.specs2.mutable._

@RunWith(classOf[JUnitRunner])
class SampleTest extends Specification {

  "The 'Hello world' string" should {
    "contain 11 characters" in {
      "Hello world" must have size(11)
    }
    "start with 'Hello'" in {
      "Hello world" must startWith("Hello")
    }
    "end with 'world'" in {
      "Hello world" must endWith("world")
    }
  }
}

获取错误：

：compileTestScala [ant：scalac]元素'/ home / ~~~~ / workspaces / ~~~~ / build / resources / main'不存在。
  [ant：scalac] /home/~~~~/workspaces/~~~~/src/test/scala/com/~~~~/ingestion/SampleTest.scala:16：   错误：value in不是String的成员
  [ant：scalac]“包含11个字符”{
  [ant：scalac]发现一个错误   ：compileTestScala失败

我正在使用Gradle（因此使用@RunWith注释）。使用specs2版本'org.specs2：specs2_2.10：2.4.15'

Answer 1

您需要为该语法扩展org.specs2.mutable.Specification而不是org.specs2.Specification。

Answer 2

如果您需要特征，请使用org.specs2.mutable.SpecificationLike

Specs2＆＃34; value in不是String＆＃34;的成员。
