From b8151e500755580850cb2947a0e9d122d544c2d3 Mon Sep 17 00:00:00 2001 From: bangerth Date: Wed, 23 Apr 2014 12:11:32 +0000 Subject: [PATCH] Output only the first few lines of numdiff output if a test fails. Then output the first 50 lines of regular diff since it's so much more readable. git-svn-id: https://svn.dealii.org/trunk@32815 0785d39b-7218-0410-832d-ea1e28bc413d --- deal.II/cmake/macros/macro_add_test.cmake | 15 +++++++++++---- 1 file changed, 11 insertions(+), 4 deletions(-) diff --git a/deal.II/cmake/macros/macro_add_test.cmake b/deal.II/cmake/macros/macro_add_test.cmake index ecbf75ec95..d2569ddde7 100644 --- a/deal.II/cmake/macros/macro_add_test.cmake +++ b/deal.II/cmake/macros/macro_add_test.cmake @@ -1,7 +1,7 @@ ## --------------------------------------------------------------------- ## $Id$ ## -## Copyright (C) 2013 by the deal.II authors +## Copyright (C) 2013, 2014 by the deal.II authors ## ## This file is part of the deal.II library. ## @@ -205,7 +205,12 @@ MACRO(DEAL_II_ADD_TEST _category _test_name _comparison_file) COMMAND rm -f ${_test_directory}/failing_diff COMMAND touch ${_test_directory}/diff COMMAND - ${${_test_diff_variable}} # see comment in line 72 + # run diff or numdiff (if available) to determine + # whether files are the same. if they are not, output + # the first few lines of the output of numdiff, followed + # by the results of regular diff since the latter is just + # more readable + ${${_test_diff_variable}} # see comment above about redirection ${_comparison_file} ${_test_directory}/output > ${_test_directory}/diff @@ -216,8 +221,10 @@ MACRO(DEAL_II_ADD_TEST _category _test_name _comparison_file) && echo "${_test_full}: DIFF failed. ------ Source: ${_comparison_file}" && echo "${_test_full}: DIFF failed. ------ Result: ${_test_directory}/output" && echo "${_test_full}: DIFF failed. ------ Diff: ${_test_directory}/failing_diff" - && echo "${_test_full}: DIFF failed. ------ Diffs as follows:" - && cat ${_test_directory}/failing_diff + && echo "${_test_full}: DIFF failed. ------ First 8 lines of numdiff/diff output:" + && cat ${_test_directory}/failing_diff | head -n 8 + && echo "${_test_full}: DIFF failed. ------ First 50 lines diff output:" + && ${DIFF_EXECUTABLE} -c ${_comparison_file} ${_test_directory}/output | head -n 50 && exit 1) WORKING_DIRECTORY ${_test_directory} -- 2.39.5
