У меня есть следующий класс:
import scala.util.{Success, Failure, Try}
class MyClass {
def openFile(fileName: String): Try[String] = {
Failure( new Exception("some message"))
}
def main(args: Array[String]): Unit = {
openFile(args.head)
}
}
Что имеет следующий unit test:
class MyClassTest extends org.scalatest.FunSuite {
test("pass inexistent file name") {
val myClass = new MyClass()
assert(myClass.openFile("./noFile").failed.get.getMessage == "Invalid file name")
}
}
Когда я запускаю sbt test
, я получаю следующую ошибку:

Определения сборки:
version := "1.0"
scalaVersion := "2.12.0"
// https://mvnrepository.com/artifact/org.scalatest/scalatest_2.11
libraryDependencies += "org.scalatest" % "scalatest_2.11" % "3.0.0"
Я не могу понять, что вызывает это. Мой класс и unit test кажутся достаточно простыми. Любые идеи?
