Question

当我使用sbt控制台运行单元测试两次或更多时，我得到以下错误。我第一次跑的时候没有任何错误。如果我从Sbt退出（Ctrl + D）并返回到Sbt，首次运行测试没有问题。使用IntelliJ。

我的测试套件包含许多测试用例，如下所示

                    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
                            }
                        }

获得以下错误

在我的测试套件中包含OneAppPerSuite解决了这个问题。

class ExampleSpec extends FlatSpec with OneAppPerSuite {

       test cases go here
}
