Ich habe das Problem, mvn test zu verwenden, um den Testcode in meinem maven scala-Code auszuführen. Hier sind die Einstellungen:
.
├── pom.xml
├── run
└── src
├── main
│ └── scala
│ └── com
│ └── myCompany
│ └── scala
│ └── MaxPrice.scala
├── resources
│ └── JCudaMultiplyBy2.ptx
└── test
├── resources
│ └── JCudaMultiplyBy2.ptx
└── scala
└── MyTest.scala
JCudaMultiplyBy2.ptx ist die Datei, in der verwendet wird MyTest.scala.
Hier ist meine pom.xml:

Der MyTest.scala-Code ist derselbe wie der MaxPrice-Code.scala code und wenn ich mvn compile und dann mvn -q scala starte: run -DmainClass = com.myCompany.scala.MaxPrice -DaddArgs = "local [*]", funktioniert es perfekt. Jetzt ändere ich den Objektnamen von MaxPrice.scala in MyTest und auch den Dateinamen in MyTest.scala. Wenn Sie "MyTest.scala" unter "src / test / scala" setzen und "mvn test" ausführen, funktioniert dies nicht und führt zu folgenden Ergebnissen:

Auch wenn ich mvn test -Dtest = MyTest ausführe, gibt es immer noch das gleiche Ergebnis: Es müssen keine Tests ausgeführt werden.
Hat jemand eine Idee? Ich habe viel gesucht, konnte aber keine Antwort finden, helfen!
Antworten:
0 für die Antwort № 1Anscheinend solltest du vom Autor verwenden scala-maven-plugin Anstatt von maven-scala-plugin (sehen Hier).
Noch wichtiger ist, Scala-Tests nach dem (allmächtigen) ausführen Dokumentation, du solltest das todsichere Plugin deaktivieren:
Um das ScalaTest Maven-Plugin zu verwenden, müssen Sie SureFire und deaktivieren ScalaTest aktivieren.
Fügen Sie im Konfigurationsbereich des todsicheren Plugins Folgendes hinzu:
<skipTests>true</skipTests>
