Is there a way we can avoid adding another new test function here? This new function is almost completely identical with the old one, except that it uses "test .. -eq" instead of "[ .. =". If the problem is just that the arguments occasionally contain superfluous spaces, I would rather see the existing function just strip the spaces. Of maybe add an option to the test to ask for arithmetic rather than string comparison. That would be preferable to introducing an new function that is confusingly similar to an existing one. > +# Like test_expect_equal, but does a numeric comparision instead of a > +# string comparision > +test_expect_equal_num () { > + exec 1>&6 2>&7 # Restore stdout and stderr > + inside_subtest= > + test "$#" = 3 && { prereq=$1; shift; } || prereq= > + test "$#" = 2 || > + error "bug in the test script: not 2 or 3 parameters to test_expect_equal" > + > + output="$1" > + expected="$2" > + if ! test_skip "$test_subtest_name" > + then > + if test "$output" -eq "$expected" > + then > + test_ok_ "$test_subtest_name" > + else > + test_failure_ "$test_subtest_name" "$output != $expected" > + fi > + fi > +} Also, the new function is missing the diff output, which is important for debugging, and the syntax is different from the standard we've been using: if ...; then We try to maintain syntax consistency across the code base. Thanks. jamie.
