🎯 What: Added tests to cover the resolve_release_query function in crates/release/src/lib.rs which previously lacked unit test coverage. Since this function relies on environment variables, testing required safe state manipulation to prevent test flakiness.

📊 Coverage:
The tests now cover:

  • Default behavior without environment variables for Stable and Beta channels.
  • Override behavior when RELEASE_BASE_URL_ENV (and legacy variants) are set.
  • Override behavior when CNB_MIRROR_ENV is set.
  • Combined behavior when both a mirror base URL and an update pinned version are specified via environment variables.

Result: Improved test coverage for core release channel logic. Test execution uses #[serial] to prevent data races during environment variable access.

Added comprehensive test coverage for the `resolve_release_query` function
in `crates/release/src/lib.rs`. The tests verify the correct resolution
of release configurations across different channels (`Stable`, `Beta`)
and correctly assert the behavior under various environment variable overrides.

Introduced `serial_test` dependency to ensure thread safety when modifying
environment variables within `unsafe` blocks for testing purposes.

Code Review

This pull request introduces comprehensive unit tests for the resolve_release_query function in crates/release/src/lib.rs to verify its behavior under various environment configurations, such as mirror URLs and pinned versions. To prevent race conditions during parallel test execution when modifying environment variables, the serial_test crate has been added as a development dependency to run these tests sequentially. No review comments were provided, and the changes are well-implemented.

Important

The consumer version of Gemini Code Assist on GitHub is being sunset. Starting June 18, 2026, new organization installations will be blocked, and all code review activity will officially cease on July 17, 2026.
