PlayFramework + ScalaTest + ScalaCheck

Я использую фреймворки, упомянутые в заголовке, со следующей конфигурацией:

"com.typesafe.play" % "sbt-plugin" % "2.4.2"

"org.scalacheck" %% "scalacheck" % "1.12.4" % "test"
"org.scalatest" %% "scalatest" % "2.2.5" % "test"
"org.scalatestplus" %% "play" % "1.4.0-M4" % "test"

С помощью простого теста с целью демонстрации:

class User
        extends FlatSpec
        with Matchers
        with Checkers {
    it should "do scala check stuff" in {
        check( ( a: Int ) ⇒ a > 100 )
    }

    it should "do scala check stuff II" in {
        check( ( a: Int ) ⇒ true )
    }
}

Похоже, в основном это работает, но вывод sbt test загроможден исключениями.

Меня также смущает тот факт, что в конце лога есть 3 отчета об испытаниях, из которых 2 не содержат никакой полезной информации.

Что касается меня, я вижу это, если мои тесты терпят неудачу: я предполагаю, что при возникновении исключения потоки не закрываются в попытке/наконец, и поэтому scala выдает все эти ужасно выглядящие сообщения....   -  person Andy Hayden    schedule 16.10.2015

Можете ли вы предоставить полный файл build.sbt? Кроме того, project/build.properties, project/plugins.sbt и java -версия?   -  person Onilton Maciel    schedule 14.02.2016

Ваш тест и код выглядят нормально.

Вы, вероятно, уже знаете это, но в любом случае ваш первый тест просто проваливается (пока не обращайте внимания на странные исключения).

Исправление первого теста, замена его на:

check( ( a: Int ) ⇒ a / 1 == a )

Мы получили:

[info] User:
[info] - should do scala check stuff (1 second, 421 milliseconds)
[info] - should do scala check stuff II (28 milliseconds)
[info] ScalaCheck
[info] Passed: Total 0, Failed 0, Errors 0, Passed 0
[info] ScalaTest
[info] Run completed in 12 seconds, 132 milliseconds.
[info] Total number of tests run: 2
[info] Suites: completed 1, aborted 0
[info] Tests: succeeded 2, failed 0, canceled 0, ignored 0, pending 0
[info] All tests passed.
[info] Passed: Total 2, Failed 0, Errors 0, Passed 2
[success] Total time: 23 s, completed Feb 14, 2016 12:44:44 AM

А как насчет этих 3 тестовых резюме?

ScalaCheck и ScalaTest — это две отдельные среды тестирования, хотя вы используете некоторые функции ScalaCheck внутри ScalaTest. Но sbt об этом не знает, и, поскольку вы включили оба фреймворка, он ищет два типа тестов и сообщает результаты для каждого фреймворка.

Вот почему отчет ScalaCheck печатается с 0 запущенными тестами. После этого запускаются тесты ScalaTest, и вы получаете отчет. Третий и последний отчет от самого sbt, обобщающий результаты всех тестовых фреймворков.

Вернемся к странным исключениям. Они появятся только в случае неудачного тестирования, так что вам не стоит о них слишком беспокоиться. Но если это вас действительно раздражает, добавьте это в свой build.sbt:

fork in Test := false

И странные исключения исчезнут.

Я воспроизвел его локально и получил ту же ошибку, и исправил ее локально :) - person Onilton Maciel; 14.02.2016

Я все еще получаю сообщение об ошибке как с parallelExecution in Test := false, так и с fork in Test := false, когда один из моих тестов терпит неудачу. - person JulienD; 08.11.2016

Это происходит только тогда, когда я тестирую вставки в базу данных. - person JulienD; 08.11.2016
