I have multiple ScalaTest classes which use BeforeAndAfterAll to construct a SparkContext and stop it afterwards like so: class MyTest extends FlatSpec with Matchers with BeforeAndAfterAll { private var sc: SparkContext = null override protected def beforeAll(): Unit = { sc = ... // Create SparkContext } override protected def afterAll(): Unit = { sc.stop() } // my tests follow } These tests run fine when started from IntelliJ IDEA, but when running sbt test , I get WARN SparkContext: Another SparkContext is being constructed (or threw an exception in its constructor). This may indicate an

In relation to a previous question , I'd like to have multiple test folders for different types of test and be able to execute the tests contained in each folder with a separate SBT action. For example, an action 'test-unit' would run only the tests contained under the folder src/test/scala/unit , and a 'test-functional' action would run only the tests under src/test/scala/functional . How would we write actions to do this? If you are using xsbt 0.10.0, you can easily create additional test configurations by defining the a full build configuration in a Scala file located in your project folder

I've wrote the following spec "An IP4 address" should "belong to just one class" in { val addrs = for { a <- Gen.choose(0, 255) b <- Gen.choose(0, 255) c <- Gen.choose(0, 255) d <- Gen.choose(0, 255) } yield s"$a.$b.$c.$d" forAll (addrs) { ip4s => var c: Int = 0 if (IP4_ClassA.unapply(ip4s).isDefined) c = c + 1 if (IP4_ClassB.unapply(ip4s).isDefined) c = c + 1 if (IP4_ClassC.unapply(ip4s).isDefined) c = c + 1 if (IP4_ClassD.unapply(ip4s).isDefined) c = c + 1 if (IP4_ClassE.unapply(ip4s).isDefined) c = c + 1 c should be (1) } } That is very clear in its scope. The test passes successfully but

We use Spec trait for our tests in ScalaTest. when we run the entire suite, it does not always run in the same order. Most answers in google suggest defining a Suite and specifying all the test names. But this requires us to add the test name every time we add a new test. Is it possible to use the DiscoverySuite itself and define the test execution order? Like run the tests in alphabetical order. I looked at extending the DiscoverySuite but DiscoverySuite seems to be private to scalatest. ---More info---- By ordering i mean, If there are tests A, B, C. class A extends Spec {..} class B extends

EDIT: This issue was a bug with sbteclipse and has been fixed When I right click on a ScalaTest suite and select Run as ScalaTest File, I get a NullPointer Exception. As a plugin, I have ScalaTest for Scala IDE 2.9.3.v-3-2_09-201309130843-55f5c32 As a jar in my library, I have scalatest_2.9.0-2.0.M5b.jar(tried scalatest_2.9.3-RC2-2.0.M5b.jar as well) Tests run in SBT Side Question: If it is a Scalatest compatibility issue between the jar and the plugin, how do I get the appropriate jar which matches the plugin? I looked here https://oss.sonatype.org/content/groups/public/org/scalatest/ but I

I am using Scalatest, FlatSpec, Spring, Selenium DSL and BeforeAndAfterAll. One of these things seems to stop ParallelTestExecution working properly. This is what happens when I run a class with two tests: One Browser opens and does some beforeAll stuff (but not Spring stuff) Another browser opens and does the beforeAll stuff Second browser gets used for first test then closes Another browser opens and does beforeAll stuff followed by second test First and Third browsers close So basically the test runs exactly the same as without ParallelTestExecution except that an extra window has opened? I

I've been using ScalaTest's FeatureSpec for a couple of days now and I'm trying to understand if it's possible to define the following spec using the built-in matchers (and if not, how I can write a suitable custom matcher). Suppose I have the class Book: case class Book(val title: String, val author: String) and in my test I have a List of books: val books = List(Book("Moby Dick", "Melville")) Now, I would like to specify that the books list should contain a book with the title "Moby Dick". I would like to write something like: books should contain (value with title "Moby Dick") I can't seem

Consider following types structure: trait HasId[T] { def id: T } case class Entity(id: Long) extends HasId[Long] Let's say, we want to mock Entity class in some test. val entityMock = mock[Entity] Mockito.when(entityMock.id).thenReturn(0) Playing such test results in throwing NullPointerException (in second line), probably because of scala compiler behaviour with wrapping primitive types (if we replace Long with String, test executes correctly). An exception or error caused a run to abort. java.lang.NullPointerException at com.test.Entity$MockitoMock$1085095743.id(Unknown Source) at com.test
