在build.sbt中为分叉测试设置JVM选项

Question

我有两组测试，一组需要与JVM -javaagent集一起运行，而另一组则需要未设置它。我Groups习惯在单独的JVM上运行，并且可以看到两个Java进程都已启动。通过使用jps -lvm我可以看到没有JVM运行带有该-javaagent标志。

build.sbt：

lazy val myProject = (project in file("."))
  .settings(
    resolvers           ++= Build.resolvers,
    libraryDependencies ++= Build.dependencies,

    fork in Test := true,
    testGrouping := groupByJavaAgent((definedTests in Test).value),
    tags in test += Tags.ForkedTestGroup -> 4
  )

val home = System.getProperty("user.home")

val jammForkOpts = ForkOptions()
  .withRunJVMOptions(Vector(s"-javaagent:$home/.ivy2/cache/com.github.jbellis/jamm/jars/jamm-0.3.3.jar"))

def groupByJavaAgent(allTests: Seq[TestDefinition]) = allTests
  .groupBy(t => if(t.name.contains("no javaagent")) ("NoJamm", ForkOptions())
                else                                ("Jamm",   jammForkOpts))
  .map { case ((gName, opts), tests) => Group(gName, tests, SubProcess(opts)) }
  .toSeq

sbt 1.2.8 scala 2.12.8

尝试像这样testGrouping通过配置来确定范围Test

Test / testGrouping := groupByJavaAgent((definedTests in Test).value)\n
