The tests are currently failing, which is intended. This PR will fix the tests: #1607 |
The dependency resolution tests were using --frozen flag (for highest) or no upgrade flag (for lowest-direct), which meant both tests just used whatever was locked in uv.lock from the main branch rather than actually resolving to the target versions. This caused the CI to miss breaking changes in new dependency versions (like pydantic 2.12) that were compatible with version constraints but not yet in the lockfile. Changes: - Use --upgrade --resolution highest for the highest resolution test - Use --upgrade --resolution lowest-direct for the lowest resolution test (both need --upgrade to ignore lockfile and re-resolve) - Simplify test execution to use --frozen --no-sync since resolution already happened during uv sync - Remove redundant UV_RESOLUTION env var (command-line flags suffice) This ensures both tests actually resolve to their intended versions and catch compatibility issues before they reach main.

This PR fixes the CI dependency resolution testing to properly test against the highest available dependency versions, which would have caught the pydantic 2.12 breaking change before it reached main.
Motivation and Context
The CI test matrix includes a "highest" resolution test intended to catch compatibility issues with newer dependency versions. However, it was using the
--frozenflag, which prevented uv from resolving to the highest available versions. Instead, it just used whatever was locked inuv.lockfrom main, defeating the purpose of testing against latest versions.This meant breaking changes in newer dependency versions (like pydantic 2.12's
FieldInforefactor) that were compatible with our version constraints but not yet in the lockfile would not be caught by CI.How Has This Been Tested?
The changes are to CI configuration only. The fix:
--resolution highestduringuv syncfor the highest resolution test--resolution lowest-directfor the lowest resolution test (unchanged behavior)uv runto use--frozen --no-syncsince resolution already happened during syncUV_RESOLUTIONenvironment variableThis ensures the highest test matrix actually resolves to and tests against the highest available versions within our constraints.
Breaking Changes
None. This is a CI configuration improvement that makes the tests work as originally intended.
Types of changes
Checklist
Additional context
This fix is related to the pydantic 2.12 compatibility issue discovered in the investigation. With this change, future dependency updates that introduce breaking changes will be caught by the "highest" resolution CI tests before merging to main.
The fix clarifies the intent of each step:
uv syncwith resolution flags → resolve and install dependenciesuv run --frozen→ run tests with what was synced (no re-resolution)
