Casper-Netsniff
Netsniff implementation in CasperJS.
This script can take a URL as argument and generate HAR file, which can be used with YSlow Command Line as input source for further performance analysis. More over, using this script as a start point, one can build automated front-end performance test with Casperjs and YSlow.
Example
Below code snippet is an example of getting HAR file from google.com.
$ casperjs netsniff.js "http://www.google.com"
This will create two files upon finish.
* test.png: screenshot of google.com
* test.har: HAR file
Below is an example of how to use this HAR file for YSlow analysis.
$ yslow --info all --format plain test.har
