saz2jmx

A utility to convert fiddler capture archive (saz) to jmeter script (jmx). It exports the jmx with good defaults and boilerplate.

Motivation

As a Performance tester (or "http hacker") we quite regularly play with tools like Fiddler which helps us to log/inspect/edit/save all http(s) traffic between the client and the server. Another favorite tool is Apache JMeter which is responsible to generating heavy http/or any kind of traffic and measuring transaction attributes. This tool/js library attempts to bridge the gap between the two by providing users to generate a jmeter script from a fiddler capture archive.

Alternatives and their pain points

• HTTP(S) Test Script Recorder: JMeter's very own http traffic recorder. The interface is hard to use and does not allow you to save the recorded data (easily 😉)
• Blazemeter Chrome Extension: doesnt save the responses which are very crucial for correlation also some bugs on GET query string conversion.

Usage

Make sure you have Nodejs and npm installed. Latest LTS Version: 10.16.0 (includes npm 6.9.0).

There are multiple options to use this library.

as a library

1. install the package npm i saz2jmx
2. sample javascript, say script.js

let saz2jmx = require('saz2jmx');
saz2jmx('c:/path/to/imported.saz', 'exports/exported.jmx');

1. Execute node script.js

as an npm executable

execute it directly without installing the package

npx saz2jmx -s source.saz -d destination.jmx

as a global command

install the package by running npm i -g saz2jmx. Then run the command as shown below.

Usage: saz2jmx [options]
 
example: saz2jmx -s source.saz -d destination.jmx
 
Options:
  -v, --version                    output the version number
  -s, --source <source>            source .saz file
  -d, --destination <destination>  destination .jmx file
  -h, --help                       output usage information

That's it, really!

TODO

• ability make samplers configurable (pass in a json maybe?)
• ability add additional jmeter components
• create jmx from bzt configs (yml) (I know its reinventing the wheel! but reinventing in JS, bzt is in python)
