  def openFile(fileName: String): Try[String]  = {

Answer 1

Try adding the following line to your build.sbt

libraryDependencies += "org.scalatest" %% "scalatest" % "3.0.1" % "test"

your build.sbt should be like this:

libraryDependencies += "org.scalactic" %% "scalactic" % "3.0.1"

libraryDependencies += "org.scalatest" %% "scalatest" % "3.0.1" % "test"

With this, the error for me is solved.
