18.5 Mocking by Overriding

Suppose we have a class that depends on a method that does some significant work and takes substantial time and resources, such as the following ​myMethod​ :

package com.agiledeveloper

public class CodeWithHeavierDependencies
{
  public void myMethod()
  {
    def value = someAction() + 10

    println(value)
  }

  int someAction()
  {
    Thread.sleep(5000) // simulates time consuming action

    return Math.random() * 100 // Simulated result of some action
  }
}

We’re interested in testing ​myMethod​ (which belongs to ​CodeWith-​​HeavierDependencies​). However, the method depends on ​someAction​ , which simulates ...
