test(controller): add unit tests for AgentCard syncPeriod validation

[Schimuneck]

Summary

Adds dedicated unit tests for the getSyncPeriod method on the AgentCard controller, covering all edge cases identified in RHAIENG-3719. Also tightens the existing happy-path RequeueAfter assertion from > 0 to the exact expected value.

Test cases added

#	Input	Expected RequeueAfter	Validates
1	"10s"	10 * time.Second	Valid short duration parsed correctly
2	"5m"	5 * time.Minute	Valid long duration parsed correctly
3	"garbage"	DefaultSyncPeriod (30s)	Invalid string falls back gracefully
4	""	DefaultSyncPeriod (30s)	Empty string falls back gracefully
5	"30s" then patched to "10s"	Changes from 30s to 10s	Live spec update takes effect on next reconcile

Code paths exercised

• getSyncPeriod in agentcard_controller.go (empty check, time.ParseDuration, error fallback)
• Reconcile return path at line 328-331 (ctrl.Result{RequeueAfter: syncPeriod})

Existing test tightened

The happy-path test ("should fetch agent card and override URL with service URL") previously asserted Expect(result.RequeueAfter).To(BeNumerically(">", 0)). Since that test uses SyncPeriod: "30s", the assertion is now Expect(result.RequeueAfter).To(Equal(30 * time.Second)).

Kind cluster validation

All behaviors confirmed manually on Kind (Kubernetes 1.35.0, Podman 5.6.2):

• syncPeriod: "10s" — operator fetches every ~10s (verified via logs)
• syncPeriod: "garbage" — operator logs "Invalid sync period, using default" and falls back to ~30s
• Live patch from "garbage" to "10s" — new period takes effect immediately

Run instructions

make test
# or focused:
go test ./internal/controller/ -v --ginkgo.focus="getSyncPeriod"

Great work, @Schimuneck !

• Clean reconcileCard helper that encapsulates the two-phase reconcile pattern without masking errors
• Complete AfterEach cleanup for all current test resources
• Proper use of Eventually for status updates (no race conditions)
• Test naming follows existing "AgentCard Controller - " convention
• Existing assertion tightened from BeNumerically(">", 0) to exact value — good improvement

Review Summary

Clean, well-structured test PR that adds comprehensive coverage for getSyncPeriod — valid durations, invalid input fallback, empty string fallback, and live spec updates. Test patterns follow existing conventions (Ginkgo BDD, proper cleanup, specific assertions). One commit, signed-off, DCO passing.

Areas reviewed: Go (tests), Commit conventions, Security
Commits: 1 commit, signed-off: ✅
CI status: passing (DCO ✅)

Highlights

• reconcileCard() helper encapsulates the two-phase reconcile pattern cleanly
• Comprehensive AfterEach cleanup for all test resources
• Tightening BeNumerically(">", 0) → Equal(30 * time.Second) is a good improvement
• Dynamic update test (30s→10s) covers a real operational scenario

Minor suggestion

The commit contains a Made-with: Cursor trailer. Per kagenti conventions, AI attribution should use Assisted-By: Cursor <noreply@cursor.com> instead of Made-with:. Not blocking — can be fixed with git commit --amend if desired.
