📝 Walkthrough

Walkthrough

Test file modifications replace clock.SetTime() calls with clock.FreezeTime() and add defer clock.UnFreeze() cleanup for clock state management in truncation tests. One subsequent freeze operation lacks the accompanying unfreeze defer.

Changes

Cohort / File(s)	Summary
Clock Control Test Updates openmeter/billing/charges/service/truncation_test.go	Switches from SetTime() to FreezeTime() for clock management in TestCreateTruncatesFlatFeeIntentAndProrationInputs and TestUsageBasedAdvanceTruncatesPersistedCalculationTimestamps. Adds defer clock.UnFreeze() after initial freeze sites, but a second FreezeTime() call in the latter test lacks a corresponding unfreeze defer.

Title check	❓ Inconclusive	The title 'fix: testcase timing' is vague and doesn't clearly convey what specific timing issue is being fixed or which test cases are affected.	Consider using a more descriptive title like 'fix: use FreezeTime instead of SetTime in truncation tests' to clearly indicate the change being made.

openmeter/billing/charges/service/truncation_test.go (1)

153-153: Consider adding a brief comment for clarity.

This works correctly because the defer clock.UnFreeze() at line 112 will clean up all frozen state when the test exits (since the clock uses a single boolean flag, not reference-counting). However, a quick reader might wonder why there's no defer here.

Totally optional—maybe just a one-liner comment like // UnFreeze handled by defer above to make the intent obvious at a glance?

✨ Optional: Add clarifying comment

-	clock.FreezeTime(datetime.MustParseTimeInLocation(s.T(), "2026-02-01T00:02:00.900Z", time.UTC).AsTime())
+	clock.FreezeTime(datetime.MustParseTimeInLocation(s.T(), "2026-02-01T00:02:00.900Z", time.UTC).AsTime()) // UnFreeze handled by existing defer
