ec2-fleet-casper

A load testing tool with a full browser. Heavily inspired by (and with lots of code from) ec2-fleet.

Requirements

• Node JS
• npm (Should probably be installed with the above).

Installing

• Clone this repository
• Install dependencies (npm install)

Configuring

• Copy the file config/default-config.json to a file called config/default.json
• Edit the file config/default.json to include your aws credentials and preferred options.

Running

Running the command ./aws.js --help should give you some hints.

A typical session may look like this:

Start some instances.

./aws.js start 10

Open the "top-like" utility to monitor when all instances are ready (typically in its own tab).

./aws.js status

Download the casper script to run on all instances.

./aws.js set testScript http://example.com/my_script.js

Switch to status tab, see that all instances get the "has_script:true" status.

Start the clients with setting the total number of runs.

./aws.js set n 200

Start some clients. Set concurrency to number of concurrent clients (this is per instance)

./aws.js set concurrency 10

Download the output (screenshots, casper output and whatnot)

./aws.js dump

The downloaded dumps will be in directories in ./dumps - one per instance.
