# This script validates whether `npm init @wordpress/block` works properly
# with the latest changes applied to the `trunk` branch. It purposefully
# avoids installing `@wordpress/scripts` package from npm when scaffolding
# a test block and uses the local package by executing everything from the
# root of the project.

# Exit if any command fails.
