Overview

NPM lock file that pins exact versions of all npm dependencies for the Spark Web UI test suite to ensure reproducible builds.

Description

ui-test/package-lock.json is an auto-generated lockfile (lockfileVersion 3) that records the complete resolved dependency tree for the ui-test project. It pins exact versions, registry URLs, and integrity hashes for Jest 30.x, jest-environment-jsdom 30.x, jQuery 3.7.x, and all their transitive dependencies including JSDOM, Babel, and various testing utilities.

Usage

This file is automatically used by `npm ci` or `npm install` within the `ui-test/` directory to install the Web UI testing framework (Jest + JSDOM). It ensures all developers and CI environments use identical dependency versions for UI tests.
