1.  class ConsoleWriter extends AnyRef

   A test-friendly wrapper for the standard system output streams (System.out, System.err).

   A test-friendly wrapper for the standard system output streams (System.out, System.err).

   Ex:

   class MyApp extends App {
     def run(): Unit = {
       val console = injector.instance[ConsoleWriter]
       console.out.println("Hello, World!")
     }
   }

   Note

   Using the ConsoleWriter is preferred for testing because its state can be locally overridden/bound, where as using System.setOut() or System.setErr() modifies global state of the JVM, which may result in flaky tests.
