The api-core test suite is very large and includes tests that can be moved closer to the code under test or into external integration tests.

Move the switch controller tests into the controller crate’s integration tests.
Move the switch CRUD API tests into the api-core integration tests.

Summary by CodeRabbit

  • Tests
    • Expanded integration coverage for switch health reporting, history, aggregation, and time-range filtering.
    • Improved validation of switch-controller workflows, including certificate setup, credential recovery, maintenance, deletion, and reprovisioning.
    • Added coverage for BMC credential rotation and failure recovery.
    • Standardized test environments and shared utilities for more consistent switch-controller testing.
    • Consolidated switch-controller test support and moved health integration tests into the shared integration suite.

Walkthrough

The PR removes switch-controller setup from API test fixtures, adds shared switch-controller integration infrastructure, migrates controller tests to the shared harness, and reorganizes switch health coverage.

Changes

Switch test infrastructure migration

Layer / File(s) Summary
Remove legacy switch fixtures
crates/api-core/src/tests/common/api_fixtures/mod.rs, crates/api-core/src/tests/mod.rs
API test fixtures no longer construct or expose the switch state controller. Obsolete switch test modules are removed.
Add shared controller test environment
crates/switch-controller/Cargo.toml, crates/switch-controller/tests/integration/common.rs, crates/switch-controller/tests/integration/main.rs
ControllerEnv and shared switch, state, service, and controller helpers are added. Test dependencies and module wiring are updated.
Migrate controller integration tests
crates/switch-controller/tests/integration/bmc_rotation.rs, crates/switch-controller/tests/integration/maintenance.rs, crates/switch-controller/tests/integration/nvos_password_rotation.rs, crates/switch-controller/tests/integration/state_controller.rs
Controller tests use ControllerEnv, shared SQLx setup, shared switch creation, and current work-lock manager access.
Reorganize switch health tests
crates/api-core/tests/integration/main.rs, crates/api-core/tests/integration/switch_health.rs, crates/switch-controller/tests/integration/health.rs
API health tests use TestHarness. Switch-controller health tests cover history deduplication, health changes, and aggregation.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🔵 Low · up to a9cb7

The PR reorganizes switch-controller tests without changing production behavior, but the shared fixture currently ignores requested locations, reducing coverage fidelity for location-dependent scenarios. The change is mergeable with explicit owner awareness and follow-up to preserve those locations.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Preserve the location in shared switch fixtures.

These migrated call sites pass a location, but crates/switch-controller/tests/integration/common.rs::new_switch ignores its _location parameter. The tests therefore create fixtures without the requested location. Preserve the location in the shared helper before relying on these scenarios to cover location-dependent behavior.
