sbt play cross build project setup: uTest runner doesn't separate client/server projects 正确

Question

我正在使用 build.sbt，它具有交叉编译设置，基本上是“Play with scala-js example”的改编版本，并且在为我的测试获得干净的设置时遇到了一些麻烦。具体来说，当运行连接我的服务器测试时，我的客户端测试也会被执行（这是我想避免的事情）。

我按照的说明进行操作并添加

libraryDependencies += "com.lihaoyi" %%% "utest" % "0.3.0"

由于某种原因，我的测试在添加

之前没有执行

testFrameworks += new TestFramework("utest.runner.Framework")

每个项目定义。也不加

"com.lihaoyi" %% "utest" % "0.3.1" % "test"

到服务器端触发一系列

not found: object utest [error] import utest._ -style errors.

根据我的印象，如果有一个干净的设置，我根本不需要添加这些额外的设置。这是我的 sbt 文件：

import sbt.Project.projectToRef
lazy val clients = Seq(client)
lazy val scalaV = "2.11.7"

lazy val server = (project in file("server")).settings(
  scalaVersion := scalaV,
  scalaJSProjects := clients,
  pipelineStages := Seq(scalaJSProd/*, gzip*/),
  resolvers += "scalaz-bintray" at "https://dl.bintray.com/scalaz/releases",
  libraryDependencies ++= Seq(
    "com.vmunier" %% "play-scalajs-scripts" % "0.3.0",
    "be.doeraene" %% "scalajs-pickling-play-json" % "0.4.0"
  ),
  testFrameworks += new TestFramework("utest.runner.Framework")
).enablePlugins(PlayScala).
  aggregate(clients.map(projectToRef): _*).
  dependsOn(sharedJvm)

lazy val client = (project in file("client")).settings(
  scalaVersion := scalaV,
  persistLauncher := true,
  persistLauncher in Test := false,
  libraryDependencies ++= Seq(
    "org.scala-js" %%% "scalajs-dom" % "0.8.0"
  ),
  testFrameworks += new TestFramework("utest.runner.Framework")
).enablePlugins(ScalaJSPlugin, ScalaJSPlay).
  dependsOn(sharedJs)

lazy val shared = (crossProject.crossType(CrossType.Pure) in file("shared")).
  settings(scalaVersion := scalaV,
    libraryDependencies ++= Seq(
    "com.lihaoyi" %%% "utest" % "0.3.1",
    "be.doeraene" %%% "scalajs-pickling-core" % "0.4.0",
    "com.lihaoyi" %%% "pprint" % "0.3.6"
    ),
    testFrameworks += new TestFramework("utest.runner.Framework")
  ).

  jsConfigure(_ enablePlugins ScalaJSPlay)
lazy val sharedJvm = shared.jvm
lazy val sharedJs = shared.js

// loads the Play project at sbt startup
onLoad in Global := (Command.process("project server", _: State)) compose (onLoad in Global).value

这里是我的问题总结：

当我运行 client/test 时，只执行客户端测试
当运行宁play-with-scalajs-example/test时，执行客户端+共享测试
奇怪的是，当运行ning server/test 我的服务器和客户端测试被执行时

如何将我的项目设置修改为

在运行ning server/test
运行在运行宁play-with-scalajs-example/test
并且在运行ning server/test 或客户端测试时还包括共享测试？

在另一个节点上，有没有办法禁用 scalatest？它导致一个相当不可读的测试输出：

sjrd 关于删除聚合的评论为我指明了正确的道路。删除它停止了

server/test

从执行服务器和客户端测试。正如 sjrd 指出的那样，聚合函数还使用运行客户端服务器上运行的每个任务。

Aggregation means that running a task on the aggregate project will also run it on the aggregated projects. (See: sbt doc)

由于我还想运行在运行ning 测试时在客户端和服务器项目上共享测试，我修改了服务器项目定义的聚合函数，并向客户端添加了一个额外的聚合项目定义。 :

服务器定义：

lazy val server = (project in file("server")).settings(
  scalaVersion := scalaV,
  scalaJSProjects := clients,
  pipelineStages := Seq(scalaJSProd/*, gzip*/),
  resolvers += "scalaz-bintray" at "https://dl.bintray.com/scalaz/releases",
  libraryDependencies ++= Seq(
    "com.vmunier" %% "play-scalajs-scripts" % "0.3.0",
    "be.doeraene" %% "scalajs-pickling-play-json" % "0.4.0",
    "com.lihaoyi" %% "utest" % "0.3.1" % "test"
  ),
  testFrameworks += new TestFramework("utest.runner.Framework")
).enablePlugins(PlayScala).
  /*
   * Executes shared tests compiled to JVM with server/test
   */
  aggregate(projectToRef(sharedJvm)). // Former: aggregate(clients.map(projectToRef): _*). before
  dependsOn(sharedJvm)

客户端定义：

lazy val client = (project in file("client")).settings(
  scalaVersion := scalaV,
  persistLauncher := true,
  persistLauncher in Test := false,
  libraryDependencies ++= Seq(
    "org.scala-js" %%% "scalajs-dom" % "0.8.0"
  ),
  testFrameworks += new TestFramework("utest.runner.Framework")
).enablePlugins(ScalaJSPlugin, ScalaJSPlay).
  /*
   * Executes shared tests compiled to JS with client/test
   */
  aggregate(projectToRef(sharedJs)).
  dependsOn(sharedJs)

当运行ning 使用 play-with-scalajs-example/test 进行测试时，现在运行s 所有测试，包括为 JS 和 JVM 单独编译的共享测试。

至于必须显式包含 utest 依赖项，客户端和服务器项目似乎不是从 crossProject 派生的，因此是断开连接的 - 将寻找更好的处理方法。
