Testing private methods is discouraged because they are, well, private
and should not be part of the interface visible to the outside.

For protected methods, you can do this (in two separate files):

class tx_foo_Bar {
  /**
   * Roasts a duck.
   *
   * @return tx_foo_Duck a well-roasted duck
   */
  protected function roastADuck() {
    ...
  }
}

and then in tests/fixtures/:

class tx_foo_TestingBar extends tx_foo_Bar {
  /**
   * Roasts a duck.
   *
   * @return tx_foo_Duck a well-roasted duck
   */
  public function roastADuck() {
    return parent::roastADuck();
  }
}

Then in the Bar test case, you use an instance of TestingBar.
