Automated Reconstruction of LoadRunner Scripts

Overview

The following are early versions of scripts I have used to cleanup and reformat LoadRunner scripts after I have recorded them. Ultimately, my intention was to automate the inclusion of parameters and other code such as standard libraries.

The Scripts

See:

• LR__fmt.py
• LR__item_data.py

Examples

chk.py
lr__.py
url_quote.py
