function testGet() {
  // Verify getting a value of a nested element.
  $value = backdrop_array_get_nested_value($this->form, $this->parents);
  $this->assertEqual($value['#value'], 'Nested element', 'Nested element value found.');

  // Verify changing a value of a nested element by reference.
  $value = &backdrop_array_get_nested_value($this->form, $this->parents);
  $value['#value'] = 'New value';
  $value = backdrop_array_get_nested_value($this->form, $this->parents);
  $this->assertEqual($value['#value'], 'New value', 'Nested element value was changed by reference.');
  $this->assertEqual($this->form['fieldset']['element']['#value'], 'New value', 'Nested element value was changed by reference.');

  // Verify that an existing key is reported back.
  $key_exists = NULL;
  backdrop_array_get_nested_value($this->form, $this->parents, $key_exists);
  $this->assertIdentical($key_exists, TRUE, 'Existing key found.');

  // Verify that a non-existing key is reported back and throws no errors.
  $key_exists = NULL;
  $parents = $this->parents;
  $parents[] = 'foo';
