/*
This script is responsible to replace a test data upload script file with a dummy script file which does not contain any sql statements

Usage:

Place the following 5 lines in the environment.properties file for the environment to which you do not want to upload test data

# Migration hooks used to prevent test data upload scripts from being executed for this environment
hook_before_each_up=JavaScript:pre-process.js
hook_after_each_up=JavaScript:post-process.js
hook_before_each_down=JavaScript:pre-process.js
hook_after_each_down=JavaScript:post-process.js

Requirements:

This script requires the corresponding post-process.js script and the dummy migration scrip 'empty_migration_script.sql' to be in the same hook folder where this script is located

// create a backup of the original migration script

// replace original migration script with a dummy script
