Esecuzione di prove Scala in Intellij

Question

Sto tentando di eseguire i test Scala (specs2) in Intellij Coummunity Edition 13.1.3. Sto ottenendo il seguente errore:

Connected to the target VM, address: '127.0.0.1:57980', transport: 'socket' 

'Start' method is not found in MyNotifierRunner null

Process finished with exit code 1 

Ecco pezzo di codice runnig a SBT, ma non riuscendo a Intellij:

class ReportsDemographicsComponentTest extends Specification with ReportsComponents { 

    "ReportsDemographicsComponent" should { 

    s"return empty list of $DeviceStatistics for an inexistent deliveryId" in DBUnitTestsUtils(2) { 
     accountId => implicit session => 

     val service = new ReportsDemographicsService(accountId) 
     val res = service.deviceStatistics(-1) 

     res.size mustEqual 0 
    } 
} 

ho provato a riavviare Intellij, SBT, progetto di pulizia, ma per il successo nu . Quando esegui test dalla riga di comando sbt, tutto è OK. Qualche idea?

Grazie

Answer 1

Nel mio caso la chiusura Idea e rigenerare la configurazione projec emettendo

sbt gen-idea 

Nota: Dovete mettere questa linea in project/plugins.sbt ad avere il comando:

addSbtPlugin("com.github.mpeltonen" % "sbt-idea" % "1.6.0")
