How to fork the jvm for each test in sbt

Question

I am working with some classes that (for some reason) can only be used once within a single VM. My test cases work if I run them individually (fork := true) ena

Answer 1

Using non-deprecated syntax:

testGrouping in Test := (definedTests in Test).value map { test =>
  Tests.Group(name = test.name, tests = Seq(test), runPolicy = Tests.SubProcess(
    ForkOptions(
      javaHome.value,
      outputStrategy.value,
      Nil,
      Some(baseDirectory.value),
      javaOptions.value,
      connectInput.value,
      envVars.value
    )))
}
