alola

curl -i <url> | alola | fx .

• glue beetween curl -i and cli JSON parser tool of your choice like jq or fx
• it was built with unix-philosophy in the mind
• runs assertions on JSON
• no bail-out: it runs every assertions
• CI-friendly: process exit code is always the number of failed testcases

# or
# npx alola (recommended)
