Unit Testing DNS Data
DNSControl performs a number of tests during the validation stage. You can find them in
pkg/normalize/validate.go
.Tests specific to your environment may be added as external tests. Output the intermediate representation as a JSON file and perform tests on this data.
Output the intermediate representation:
dnscontrol print-ir --out foo.json --pretty
NOTE: The
--pretty
flag is optional.Here is a sample test written in
bash
using the jq command. This fails if the number of MX records in the stackex.com
domain is not exactly 5:COUNTMX=$(jq --raw-output <foo.json '.domains[] | select(.name == "stackex.com") | .records[] | select(.type == "MX") | .target' | wc -l)
echo COUNT=:"$COUNTMX":
if [[ "$COUNTMX" -eq "5" ]]; then
echo GOOD
else
echo BAD
fi
Manipulating JSON data is difficult. If you implement ways to make it easier, we'd gladly accept contributions.
