Using Shell Script to test your server

Sometimes, depending of your team or project language, is much easier to use shell script to test your API Server. After some time using this template, i resolved to share. I hope that helps others developers too.

Depends on:

• bash
• curl

Tested on Ubuntu 13.04 64bit.

#!/bin/bash

URL=http://localhost:8080

## Unit-Testable Shell Scripts (http://eradman.com/posts/ut-shell-scripts.html)
typeset -i tests_run=0
function try { this="$1"; }
trap 'printf "$0: exit code $? on line $LINENO\nFAIL: $this\n"; exit 1' ERR
function assert {
    let tests_run+=1
    [ "$1" = "$2" ] && { echo -n "."; return; }
    printf "\nFAIL: $this\n'$1' != '$2'\n"; exit 1
}
## end

try "Example of GET and test for 404 status"

out=$(curl -s -w "%{http_code}" $URL)
assert "404" "$out"

try "Example of POST XML"

# Post xml (from hello.xml file) on /hello
out=$(cat test/hello.xml | curl -s -H "Content-Type: text/xml" -d @- \
  -X POST $URL/hello)
assert "Hello World" "$out"
