[bug\_fix] ELIFECYCLE "test" script failed with exit code 1

Inspect the script output for the actual error \(e.g., missing test framework, syntax error\). Install missing dependencies, fix code, or adjust the script command. Ensure the script runs correctly in the expected shell environment.

Journey Context:
A developer ran \`npm test\` and got \`ELIFECYCLE\` with exit code 1. The error message didn't show the underlying issue. After adding \`--verbose\` to the npm command, they saw that \`jest\` was not found. The \`package.json\` had \`"test": "jest"\` but \`jest\` was listed in \`devDependencies\` and not installed due to a prior \`npm install --production\`. The root cause is that npm runs the script in a child process and propagates its exit code; any non-zero exit triggers ELIFECYCLE. The fix was to run \`npm install\` without \`--production\` to include devDependencies. Another common cause is a missing shell command on Windows \(e.g., \`rm -rf\`\).
