How to run the Play app before testing and then close it in specs2?

Question

My goal is to run the application and run several tests in one instance of the application.

I tried this solution without much luck. Here is my test:

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
        }

    }
  }

}

The problem is that the application starts and stops immediately, and the tests run without starting the application:

[debug] c.j.b.BoneCPDataSource - JDBC URL = jdbc:h2:/tmp/play-test--437407884;MODE=PostgreSQL;DATABASE_TO_UPPER=false;DB_CLOSE_DELAY=-1, Username = zalando, partitions = 1, max (per partition) = 30, min (per partition) = 5, idle max age = 10 min, idle test period = 1 min, strategy = DEFAULT

Answer 1

In specifications2, there is a distinction between test declaration and test execution. When you write "application" should ..., you simply declare tests. The executable part is what is contained in the part ... in ....

, running(AppWithTestDb2) { ... }, AppTestDb2.

, specs2, - Steps :

class ApplicationSpec extends Specification { sequential

  step("start application")

  "Application" should {
    "send 404 on a bad request" in { ... }

    "post signup request" in { ... }
  }

  step("stop application")
}

, specs2, , , ( sequential )

Play, , WithApplication - /. , .

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())
