scalatest

I'm using ScalaTest with the Akka TestKit to write unit and integration tests for an actor I've coded to simply send a message to another actor without mutating any internal state. Take this for example: class MyActor extends Actor { val anotherActor = context.actorOf(Props[AnotherActor]) def receive: Receive = { case MyMessage => anotherActor ! AnotherMessage } } I want to write a test that confirms that anotherActor processed AnotherMessage as a consequence of MyActor processing MyMessage . The classic example is to use TestActorRef to get at the underlying actor and check for some internal

I am new to scala and I am trying out few sample codes for testing. However I am facing some issues when I run the test code. When I run the test, I am getting an error [trace] Stack trace suppressed: run last test:executeTests for the full output. [error] (test:executeTests) java.lang.NoClassDefFoundError: scala/Product$class [error] Total time: 3 s, completed Feb 27, 2017 6:57:15 PM My code is as follows FilterChecks.scala class filterChecks extends FlatSpec { "Filter checker passed a filename which is present in directory" should "return file name" in { val matchingFileName = new FileObject

I started working my way through the Scala Koans , which is organized around a suite of unit tests with blanks that one needs to fill in. (This idea was modeled after a similar Ruby Koans project.) You start the sbt tool running a test, and it admonishes: [info] + ***************************************** [info] + [info] + [info] + [info] + Please meditate on koan "None equals None" of suite "AboutEmptyValues" [info] + [info] + [info] + [info] + ***************************************** ...and so you go look at this unit test and it says: test("None equals None") { assert(None === __) } ...and

I need to populate my ScalaTest tests with @Autowired fields from a Spring context, but most Scalatest tests (eg FeatureSpec s can't be run by the SpringJUnit4ClassRunner.class - @RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration(locations="myPackage.UnitTestSpringConfiguration", loader=AnnotationConfigContextLoader.class) public class AdminLoginTest { @Autowired private WebApplication app; @Autowired private SiteDAO siteDAO; (Java, but you get the gist). How do I populate @Autowired fields from an ApplicationContext for ScalaTest? class AdminLoginFeatureTest extends FeatureSpec

import org.scalatest.{ FlatSpec, Matchers, ParallelTestExecution } import org.scalatest.concurrent.ScalaFutures import org.apache.thrift.TApplicationException class Test extends FlatSpec with Matchers with ScalaFutures with ParallelTestExecution { it should "throw org.apache.thrift.TApplicationException for invalid Ids" in { val future: Future[Response] = ThriftClient.thriftRequest whenReady(future) { res => { intercept[TApplicationException] { } } } } } Question: How do you assert expected failures in Futures without blocking? The above doesn't work, the exception is thrown before the
