Don Cragun's little awk script does exactly that - loop through ALL test-?????? files around, where ?????? matches the file names the sample numbers you post: 000000, 000001, 000002, etc.
If - as he explains - the echo command is removed, and the schript's output is piped through sh, all your test files should be renamed according to your spec. That is - if all files contain DIFFERENT strings as $4 in their first line. If not, files with lower numbers might be overwritten by the ones with higher number and identical $4.
EDIT: To avoid that problem, consider this small adaption of Don Cragun's script:

logcheck-test(1) General Commands Manual logcheck-test(1)NAME
logcheck-test - test new logcheck rules easily
SYNOPSIS
logcheck-test [-q|-i] [-a|-s|-l FILE] [-e] [-P PREFIX] [-S SUFFIX] RULE
logcheck-test [-q|-i] [-a|-s|-l FILE] -r RULEFILE
DESCRIPTION
logcheck-test parses a log file for matching lines specified by a single rule or a rule file. If using a single RULE you can set a PREFIX
and a SUFFIX to write new rules easily.
OPTIONS -h, --help
Show usage information
-a, --auth.log
Parse /var/log/auth.log for matching lines
-s, --syslog
Parse /var/log/syslog for matching lines
-l, --log-file FILE
Parse FILE for matching lines
-i, --invert-match
Show line that don't match the RULE or the RULEFILE
-q, --quiet
Suppress rule summary at the end of output
-e, --surround-rule
Surround RULE with standard prefix and suffix:
^[[:alpha:]]{3} [ :[:digit:]]{11} [._[:alnum:]-]+ RULE$
-P, --append-prefix PREFIX
Append PREFIX to rule prefix. Option can be given multiple times
-S, --prepend-suffix SUFFIX
Prepend SUFFIX to rule suffix. Option can be given multiple times
-r, --rule-file RULEFILE
Use file RULEFILE for rule input
EXAMPLES
With logcheck-test you can easily write and test new rules.
Test a single rule against /var/log/syslog:
logcheck-test -s "RULE"
Test a single rule against ~/log, surround the rule with standard prefix and suffix and append "kernel " to prefix:
logcheck-test -l ~/log -e -P "kernel " "RULE"
Test the rules in rulefiles/linux/ignore.d.server/kernel against ~/log:
logcheck-test -l ~/log -r rulefiles/linux/ignore.d.server/kernel
Test which lines the rules in rulefiles/linux/ignore.d.server/kernel doesn't match:
logcheck-test -l ~/log -r rulefiles/linux/ignore.d.server/kernel -i
EXIT STATUS
On successful matching logcheck-test will complete with exit code 0. An exit code of 1 indicates no successful matching.
An exit code greater then 1 indicates an error occurred. Textual errors are written to the standard error stream.
