lightweight-browser-load-tester/examples/localstorage-randomization.yaml

A lightweight load testing tool using real browsers for streaming applications with DRM support

# localStorage Randomization Examples
# This configuration demonstrates various randomization patterns for localStorage
# to simulate diverse user scenarios and realistic load testing conditions

# Basic test configuration
concurrentUsers: 8
testDuration: 180  # 3 minutes
rampUpTime: 20     # 20 seconds to ramp up all users

# Note: This configuration uses additional predefined arrays that would be available:

# These arrays can be extended in the browser pool configuration or loaded from files:
