Akka/Scala example source code file (TestTimeSpec.scala)

This example Akka source code file (TestTimeSpec.scala) is included in my "Source Code Warehouse" project. The intent of this project is to help you more easily find Akka and Scala source code examples by using tags.

All credit for the original source code belongs to akka.io; I'm just trying to make examples easier to find. (For my Scala work, see my Scala examples and tutorials.)

Akka tags/keywords

a, akkaspec, concurrent, duration, test, testing, testkit, testprobe, testtimespec, time, timingtest

The TestTimeSpec.scala Akka example source code

package akka.testkit

import scala.concurrent.duration._
import org.scalatest.exceptions.TestFailedException

@org.junit.runner.RunWith(classOf[org.scalatest.junit.JUnitRunner])
class TestTimeSpec extends AkkaSpec(Map("akka.test.timefactor" -> 2.0)) {

  "A TestKit" must {

    "correctly dilate times" taggedAs TimingTest in {
      1.second.dilated.toNanos should be(1000000000L * testKitSettings.TestTimeFactor)

      val probe = TestProbe()
      val now = System.nanoTime
      intercept[AssertionError] { probe.awaitCond(false, Duration("1 second")) }
      val diff = System.nanoTime - now
      val target = (1000000000l * testKitSettings.TestTimeFactor).toLong
      diff should be > (target - 500000000l)
      diff should be < (target + 500000000l)
    }

    "awaitAssert must throw correctly" in {
      awaitAssert("foo" should be("foo"))
      within(300.millis, 2.seconds) {
        intercept[TestFailedException] {
          awaitAssert("foo" should be("bar"), 500.millis, 300.millis)
        }
      }
    }

    "throw if `remaining` is called outside of `within`" in {
      intercept[AssertionError] {
        remaining
      }
    }

  }
}
