libraryDependencies += "org.scalatest" %% "scalatest" % "3.1.0" % "test"

Compiling & Running test using Scala

Download the ScalaTest jar file. This is available on Quickstart page
Download the scala-xml jar file
Compile the Test class

scalac -classpath "*.jar" HelloWorldSpec.scala

scala -classpath "*.jar" org.scalatest.run HelloWorldSpec

Module 07 - Mocking and Tagging Your Tests

The latest ScalaMock release 4.4.0 has not been updated with the latest ScalaTest release 3.1.0. There is an open pull request to merge the changes.

However, there are no breaking or conflicting changes between ScalaTest and ScalaMock. So, in order to learn ScalaMock, you can learn it with the ScalaTest release 3.0.8 which is 1 release behind the latest ScalaTest 3.1.0.
