Summary of Changes

Hello @jaredwray, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request focuses on improving the test coverage and robustness of the certificate generation module. By exposing and thoroughly testing key internal utility functions related to integer encoding and IPv6 address expansion, the changes ensure that these critical components behave as expected under various conditions, contributing to a more reliable certificate generation process.

Highlights

• Testability Improvement: Exported the internal utility functions encodeInteger and expandIpv6 from src/certificate.ts as _encodeInteger and _expandIpv6 respectively, specifically for testing purposes.
• Enhanced Test Coverage for _encodeInteger: Added new unit tests for the _encodeInteger function, covering scenarios such as encoding zero, and handling numbers and buffers where the high bit is set, ensuring correct DER INTEGER encoding.
• Enhanced Test Coverage for _expandIpv6: Implemented new unit tests for the _expandIpv6 function to verify its ability to correctly pad groups in fully-expanded IPv6 addresses and expand the :: shorthand notation for both left and right empty sides.
• IPv6 AltName Handling Test: Included a new test case for generateCertificate to confirm its proper handling of fully-expanded IPv6 altNames without the :: shorthand.

Changelog

• src/certificate.ts
  • Exported internal functions encodeInteger and expandIpv6 for testing.
• test/certificate.test.ts
  • Imported newly exported internal functions _encodeInteger and _expandIpv6.
  • Added new test suite for _encodeInteger covering various encoding scenarios.
  • Added new test suite for _expandIpv6 to validate IPv6 address expansion.
  • Added a new test case for generateCertificate to verify IPv6 altName handling.

Code Review

This pull request successfully increases test coverage by exporting and testing two internal functions, encodeInteger and expandIpv6. The new tests are well-written and cover important cases. I've added a couple of suggestions to make the test suite for expandIpv6 more comprehensive and to address a potentially brittle assertion in one of the new tests that relies on a specific output format from Node.js's crypto module.
