如何在测试之前启动Play应用程序,然后在specs2中将其关闭？

Question

我的目标是让应用程序运行并在应用程序的同一个实例上执行多个测试.

我没有太多运气试过这个解决方案.这是我的测试:

class ApplicationSpec extends Specification { sequential


  object AppWithTestDb2 extends FakeApplication(additionalConfiguration = 
    Map(
    ("db.default.driver") -> "org.h2.Driver",
    ("db.default.url") -> (
//        "jdbc:h2:mem:play-test-" + scala.util.Random.nextInt +      // in memory database 
        "jdbc:h2:/tmp/play-test-" + scala.util.Random.nextInt +     // file based db that can be accessed using h2-browse in activator
        ";MODE=PostgreSQL;DATABASE_TO_UPPER=false;DB_CLOSE_DELAY=-1")
    ))

    running(AppWithTestDb2) {

      "Application" should {

        "send 404 on a bad request" in {
          route(FakeRequest(GET, "/boum")) must beNone
        }

        "post signup request" in {
          val res = route(FakeRequest(POST, "/user", FakeHeaders(), TestData.newUser)).get
                  status(res) must equalTo(OK)
                  contentType(res) must beSome("application/json")
                  contentAsJson(res) mustEqual TestData.newUser
        }

        "fail signup request for existing user" in {
          val res1 = route(FakeRequest(POST, "/user", FakeHeaders(), TestData.newUser)).get
                  Await.result(res1, Duration.Inf)
                  val res = route(FakeRequest(POST, "/user", FakeHeaders(), TestData.newUser)).get
                  Await.result(res, Duration.Inf)
                  status(res) must equalTo(CONFLICT)
                  contentType(res) must beSome("application/json")
                  contentAsJson(res) mustEqual TestData.newUser
        }

    }
  }

}

这里的问题是应用程序立即启动和停止,并且在没有运行的应用程序的情况下执行测试

这是我的工作解决方案

object AppWithTestDb2 extends FakeApplication(additionalConfiguration = 
Map(
    ("db.default.driver") -> "org.h2.Driver",
    ("db.default.url") -> (
//        "jdbc:h2:mem:play-test-" + scala.util.Random.nextInt +      // in memory database 
        "jdbc:h2:/tmp/play-test-" + scala.util.Random.nextInt +     // file based db that can be accessed using h2-browse in activator
        ";MODE=PostgreSQL;DATABASE_TO_UPPER=false;DB_CLOSE_DELAY=-1")
))


class SignupLoginSpec extends Specification { sequential


    step(Play.start(AppWithTestDb2))

  "application" should {

    "post signup request" in {
      val res = route(FakeRequest(POST, "/user", FakeHeaders(), TestData.newUser)).get
      status(res) must equalTo(OK)
      contentType(res) must beSome("application/json")
      contentAsJson(res) mustEqual TestData.newUser
    }

    "fail signup request for existing user" in {
      val res1 = route(FakeRequest(POST, "/user", FakeHeaders(), TestData.newUser)).get
      Await.result(res1, Duration.Inf)
      val res = route(FakeRequest(POST, "/user", FakeHeaders(), TestData.newUser)).get
      Await.result(res, Duration.Inf)
      status(res) must equalTo(CONFLICT)
      contentType(res) must beSome("application/json")
      contentAsJson(res) mustEqual TestData.newUser
    }

  }

  step(Play.stop())

}
