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。
我试过this solution没有太多运气。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,并且在没有正在运行的应用程序的情况下执行测试:
[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

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())
}
答案 1 :(得分:2)
在specs2中,测试声明和测试执行之间存在区别。当您编写"application" should ...
时,您只需声明测试。可执行部分包含在... in ...
部分中。
因此,当您声明running(AppWithTestDb2) { ... }
时,您只需在AppTestDb2
应用程序的上下文中创建一些测试。
您希望在specs2中实现的目标的一般解决方案是使用Steps
,如下所示:
class ApplicationSpec extends Specification { sequential
step("start application")
"Application" should {
"send 404 on a bad request" in { ... }
"post signup request" in { ... }
}
step("stop application")
}
然后,specs2执行模型的工作方式,您将在所有测试开始之前启动假应用程序,并在所有测试完成后终止(无论您是否使用sequential
)
我不是Play用户,但我怀疑您应该能够重用WithApplication
类或类似的东西来创建启动/停止步骤。否则,有一篇博文here正在探索针对同一问题的解决方案。
