This PR enhances the verify_lazy.js script to provide stronger validation of API lazy-loading behavior in the google-api-nodejs-client.
The existing script performed basic access checks but did not verify whether APIs were exposed via JavaScript getters, which is a key indicator of lazy loading. This change improves diagnostic accuracy by explicitly inspecting property descriptors and validating runtime behavior for commonly used APIs.
Changes Made
Added checks using Object.getOwnPropertyDescriptor to verify APIs are implemented as getters
Improved logging for clearer verification output
Added runtime validation for commonly used APIs (drive, gmail, youtube)
Refactored code for better readability and maintainability
Notes for Reviewers
This script depends on compiled output (build/src); please run npm run compile before execution
No runtime or production code paths were modified
Changes are limited to internal verification tooling
Impact
Improves confidence in the library’s lazy-loading architecture and strengthens internal verification without introducing breaking changes.
