问题 task scalaTest(dependsOn: testClasses) << { description = 'Runs Scalatest suite' ant.taskdef(name: 'scalatest', classname: 'org.scalatest.tools.ScalaTestAntTask', classpath: sourceSets.test.runtimeClasspath.asPath ) ant.scalatest(runpath: sourceSets.test.output.classesDir, haltonfailure: 'true', fork: 'false') { reporter(type: 'stdout') } } I run gradle scalaTest and I get: * What went wrong: Execution failed for task ':scalaTest'. > java.lang.NoClassDefFoundError: scala/reflect/ClassManifest

问题 I have a companion object with a private method, like so: package com.example.people class Person(val age: Int) object Person { private def transform(p: Person): Person = new Person(p.age + 1) } I would like to test this method, with something like: class PersonSpec extends FlatSpec { "A Person" should "transform correctly" in { val p1 = new Person(1) val p2 = Person.transform(p1) // doesn't compile, because transform is private! assert( p2 === new Person(2) ) } } Any help on having test code

问题 I'm trying to use the scalacheck property generators in a scalatest.FlatSpec test file. The test should fail and be reported by junit framework (and eclipse in my case) but the test pass and error is just displayed in console. import scala.collection.immutable.TreeSet import org.junit.runner.RunWith import org.raisercostin.namek.UnitSpec import org.scalatest.junit.JUnitRunner import org.scalatest.FlatSpec import org.scalatest._ @RunWith(classOf[JUnitRunner]) class SetsTest2 extends FlatSpec

问题 I am using selenium to perform integration tests on a Scala web app. I would like to either screenshot or print the html of a page into the console whenever a test fails. My current set up is Scalatest using Selenium 2.0, with Spec. Is there anyway to intercept a failure or determine the state of a test from a AfterEach override method? 回答1: To do that you'll want to override withFixture instead of using BeforeAndAfterEach. BeforeAndAfterEach's beforeEach method happens before the test, and

问题 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

问题 The way to do this for specs2 based test in sbt is (testOptions in Test) += Tests.Argument(TestFrameworks.Specs2, "html") but how about scalatest? I've done lots of Google search, but cannot find a good explanation/solution. 回答1: so two things I need to do... I. use any scalatest artifact after 2.0.M5b. For me, I added this dependency, org.scalatest" %% "scalatest" % "2.0.M6" % "test->*" excludeAll ( ExclusionRule(organization="org.junit", name="junit") ) "test->*" is necessary, otherwise

问题 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

问题 I'm trying to unit-test some Scala that is very collection-heavy. These collections are returned as Iterable[T] , so I am interested in the contents of the collection, even if the underlying types differ. This is actually two related problems: How do I assert that two ordered collections contain the same sequence of elements? How do I assert that two unordered collections contain the same set of elements? In summary, I'm looking the Scala-equivalent of NUnit's CollectionAssert.AreEqual
