使用 Scalatest 测试 ScalikeJDBC Publisher

Question

你知道为什么这段代码它应该 "add person s and then find-by-firstname" in { implicit session: DBSession => val person1: Person = Person.create(firstname1, lastname1, ssn1, email1, dob1).get val person3: Person = Person.create(firstname1, lastname3, ssn3, email3, dob3).get

val publisher1: DatabasePublisher[Person] = Person.findByFirstName(firstname1)

val probe1 = TestSink.probe[Person](actorSystem)
val (_, sink) = Source
  .fromPublisher(publisher1)
  .toMat(probe1)(Keep.both)
  .run()

sink.request(2)
sink.expectNext(person1, person3)
sink.expectComplete()

}

会出现这个错误

？不知道为什么两个onNext电话好像漏接了

Answer 1

这样就可以了。

val person1: Person = Person.create(firstname1, lastname1, ssn1, email1, dob1).get val person3: Person = Person.create(firstname1, lastname3, ssn3, email3, dob3).get

val publisher1: DatabasePublisher[Person] = Person.findByFirstName(firstname1)

val results1Future: Future[Seq[Person]] =
  Source.fromPublisher(publisher1).take(2).runWith(Sink.seq)

val results1: Seq[Person] = Await.result(results1Future, Duration(5, TimeUnit.SECONDS))

results1 should contain(person1)
results1 should contain(person3)
