Play 2.5.3 - Running Scalatest on console, getting java.lang.NoClassDefFoundError: Could not initialize class play.api.Play$

Question

I get below error when I run the unit tests using sbt console twice or more. I do not get any error when I run for the first time. If I get out from Sbt (Ctrl+D) and go back to Sbt, there is no issue with running the tests for the first time.Using IntelliJ.

My test suites contain many test cases like below

                    val timeOutSpan = 5
                    val intervalSpan = 500
                    implicit val defaultPatience =
                        PatienceConfig(timeout = Span(timeOutSpan, Seconds), interval = Span(intervalSpan, Millis))

                     it should "get houses" in {
                            val index: Future[Result] = destinations.index
                                .apply(FakeRequest(GET, "/houses"))
                            whenReady(index){ index =>
                                index.header.status shouldBe 200
                            }
                        }

Getting below error

why you do not try to use `2.5.12` ? see if this issue happen? i'm not sure but there was an issue around this part in first 2.5.x versions — Al-Mothafar, Feb 01 '17 at 22:20
@Al-Mothafar I tried your suggestion but I get the same error. I am looking into this [link](http://stackoverflow.com/questions/34413/why-am-i-getting-a-noclassdeffounderror-in-java/34419#34419) post and still looking for a solution. — ecamur, Feb 02 '17 at 16:16

Including OneAppPerSuite in my test suite solved the issue.

class ExampleSpec extends FlatSpec with OneAppPerSuite {

       test cases go here
}
