Command

mkdir -p src/main/scala/com/example/hello
mkdir -p src/test/scala/com/example/hello

Hello.scala

package com.example.hello

import breeze.linalg._

object Hello {
  def main(args: Array[String]) {
    val m23 = DenseMatrix(
      (1.0d, 2.0d, 3.0d),
      (4.0d, 5.0d, 6.0d))

    val plusall = m23 + 0.1d

    println(m23)
    println(plusall)
  }
}

HelloTest.scala

package com.example.hello

import org.scalatest.FunSuite

class HelloTest extends FunSuite {
  test("Hello should run main") {
    expectResult()(Hello.main(Array.empty))
  }
}
