Question

我使用scalatest作为我的测试框架，这是我的测试代码：

import org.scalatest.FunSuite

class SampleTest extends FunSuite{

   test("hello") {
     println(s"sdfsf")
   }
}

build.sbt settings

  val scalatestJS = libraryDependencies += "org.scalatest" %%% "scalatest" % Version.scalatest % Test

  val scalatestJSSettings = Seq(
    scalatestJS,
    scalaJSStage in Global := FastOptStage,
    //    scalaJSStage in Global := FullOptStage,
//    jsDependencies += RuntimeDOM,
//    jsDependencies += ProvidedJS / "test-bundle.js" % Test,
    jsEnv in Test := new PhantomJS2Env(scalaJSPhantomJSClassLoader.value, addArgs = Seq("--web-security=no"))
//        jsEnv in Test := new NodeJSEnv()
  )

注意：这用于正常工作但不再是：s

修改：

ScalaTest：3.0.0-M15

ScalaJS：0.6.9

斯卡拉：2.11.8

Phantom JS：2.0.0

Answer 1

在我的代码中，我有一个扩展js class

的类

@ScalaJSDefined
class MyLab(container : dom.Node) extends JSLab(container) {... }

即使我在我的测试中没有使用这个类，看起来为这一行生成的源代码也是在全球范围内寻找JSLab的一些方法！这会导致幻影崩溃。有趣的是，测试在Rhino上正常运行：s。无论如何，我添加了JSLab作为测试依赖和错误。

我不知道在这里应该归咎于谁，是不是愚蠢的开发人员（我）在解决问题或scala.js时朝着不同的方向前进，因为没有帮助解决为什么phantomjs坠毁：s

org.scalajs.jsenv.ExternalJSEnv $ NonZeroExitException：PhantomJS2以代码2退出
