From c849e72c0b216578f96b763529c5e58056d0662c Mon Sep 17 00:00:00 2001 From: Ron Yorston Date: Thu, 21 Jan 2021 08:40:54 +0000 Subject: nl: ensure '-b n' option displays file content The command 'nl -b n' should output no line numbers, just some spaces as a placeholder followed by the actual file content. Add tests for line numbering by cat and nl. The correct results were obtained from coreutils. function old new delta print_numbered_lines 152 157 +5 .rodata 182456 182453 -3 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 1/1 up/down: 5/-3) Total: 2 bytes Signed-off-by: Ron Yorston Signed-off-by: Denys Vlasenko --- testsuite/nl.tests | 39 +++++++++++++++++++++++++++++++++++++++ 1 file changed, 39 insertions(+) create mode 100755 testsuite/nl.tests (limited to 'testsuite/nl.tests') diff --git a/testsuite/nl.tests b/testsuite/nl.tests new file mode 100755 index 000000000..95e7abb58 --- /dev/null +++ b/testsuite/nl.tests @@ -0,0 +1,39 @@ +#!/bin/sh +# Copyright 2021 by Ron Yorston +# Licensed under GPLv2, see file LICENSE in this source tree. + +. ./testing.sh + +# testing "test name" "commands" "expected result" "file input" "stdin" + +testing "nl numbers all lines" \ + "nl -b a input" \ +"\ + 1 line 1 + 2 + 3 line 3 +" \ + "line 1\n\nline 3\n" \ + "" + +testing "nl numbers non-empty lines" \ + "nl -b t input" \ +"\ + 1 line 1 + + 2 line 3 +" \ + "line 1\n\nline 3\n" \ + "" + +testing "nl numbers no lines" \ + "nl -b n input" \ +"\ + line 1 + + line 3 +" \ + "line 1\n\nline 3\n" \ + "" + +exit $FAILCOUNT -- cgit v1.2.3
