play framework + ScalaTest + ScalaCheck

sto utilizzando i quadri citati nel titolo con la seguente configurazione:play framework + ScalaTest + ScalaCheck

"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"

Con un semplice test ai fini della dimostrazione:

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) 
    } 
}

sembra fondamentalmente funziona, ma l'output sbt test è pieno di eccezioni.

Sono anche confuso dal fatto che ci sono 3 sommari test alla fine del registro, di cui 2 contengono alcuna informazione utile.

Hai mai risolto questo? (dannazione: https://xkcd.com/979/) –

@AndyHayden sfortunatamente no, ancora di fronte a questo numero – Taig

Per me, vedo questo se i miei test falliscono: la mia ipotesi è che quando viene sollevata un'eccezione, i flussi non sono " t chiuso in un tentativo/finalmente, e così scala barf su tutti questi messaggi dall'orribile aspetto .... –

Il test e il codice sembrano ok.

Probabilmente lo sapete già, ma in ogni caso, il vostro primo test sta fallendo (non importa ancora le strane eccezioni).

Fissaggio del primo test, sostituendolo con:

check((a: Int) ⇒ a/1 == a)

Otteniamo:

[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

che dire di quei 3 riepiloghi dei test?

ScalaCheck e ScalaTest sono due quadri di test separati, anche se si sta utilizzando alcune delle funzionalità di ScalaCheck all'interno di ScalaTest. Ma sbt non lo sa e visto che hai incluso entrambi i framework, cerca i due tipi di test e riporta i risultati per ogni framework.

Ecco perché il report di ScalaCheck viene stampato con 0 test eseguiti. Dopo questo, i test di ScalaTest vengono eseguiti e si ottiene il report. Il terzo e ultimo report proviene da SBT stesso, che riassume i risultati di tutti i framework di test.

Torna alle eccezioni strane, verranno visualizzate solo se i test non funzionano, quindi non dovresti preoccuparti troppo di loro. Ma se è veramente fastidioso, aggiungere questo alla tua build.sbt:

fork in Test := false

E le strane eccezioni andrà via.

Non ho più il codice/progetto in giro che ha causato questi problemi, ma dal momento che la tua risposta sembra ben concepita, lo accetto per ora. – Taig

L'ho riprodotto localmente e ho ottenuto lo stesso errore, e l'ho risolto localmente :) –

Ho ancora ricevuto l'errore con entrambi gli esempi di 'parallelExecution in Test: = false' e fork in Test: = false' quando uno dei miei test sta fallendo . – JulienD
