How to measure and display the running time of a single test?

Question

I have a potentially long-running test written with scalatest:

test(\"a long running test\") {
  failAfter(Span(60, Seconds)) {
    // ...
  }
}

In addition to r.v.'s answer: If you have multiproject builds the testOptions in Test += Tests.Argument("-oD") does not work on root level in build.sbt, because Test refers to src/test/scala. You have to put it inside your Sub-Project settings

Project(id = "da_project", base = file("da_project"))
    .settings(
        testOptions in Test += Tests.Argument("-oDG"),
        libraryDependencies ++= Seq(
            ...
        )
    )
