#  Test new functionality of ConfigFileEditor::delete
#

use strict;
use Test;
use ConfigFileEdit;


#
#   Tests  we plan are:
#   Delete a line from the middle of the test file
#     with a pile of consistency test.
#   Delete a line from the end of the test file 
#     with a pile of consistency tests.
#  NOTE: deleting from the beginning is the same as
#    from the middle.
#

BEGIN {plan tests => 8}

#
#   Test deletion of middle element.
#   - Use the test file test2config.cfg
#   - Delete the line with key line2
#   - Total number of lines should go down by 1.
#   - line1 - index should not change.
#   - last  - index should go down by 1.
