How do I stub out a protected method in a object in scala

Example:

object Test {

  def test = {
    doTest
  }

  protected def doTest = {
  // do something
  }
}

class MockTest extends WordSpec with Mockito{
  "" in {
    val t = spy(Test)

    // how do i stub out doTest?
  }
}

I have a Test class with a protected doTest method. How do I stub out this protected method?

I would advise to make doTest package private, so that clients of your object won't be able to call it, but you'll be able to test it from within the same package.

package com.company.my.foo

object Test {

  def test = {
    doTest
  }

  private[foo] def doTest = {
  // do something
  }
}

and 

package com.company.my.foo

class MockTest extends WordSpec with Mockito{
  "" in {
    val t = spy(Test)

    when(t.doTest()).thenReturn("foo")
  }
}

Test is a singleton (all Scala objects are), you can subclass a class, but not an object. Hence protected is a bit meaningless here - you're saying this method should only be accessible to subclasses, but it's not possible to have any (since Test is an object).

You have a couple options depending on what is best suited to your needs. 1) you can make Test a class and then extend it, or 2) change the access level of doTest to public [which is the default in Scala if you don't specify an access modifier]
