Estimated code review effort: 3 (Moderate) | ~30 minutes Merge Risk: 🟡 Moderate · up to The PR adds manager tests and changes malware container-state cleanup, but the current implementation can retain stale state after container removal and may leak a goroutine during lifecycle handling.

In `@pkg/healthmanager/health_manager_test.go`:
- Around line 3-10: Update the HTTP request setup in the health manager tests to
use httptest.NewRequestWithContext with context.Background(), replacing all
three httptest.NewRequest calls, and add the context import.
In `@pkg/malwaremanager/v1/malware_manager_test.go`:
- Around line 204-244: Update TestContainerCallback_AddRemove to wait beyond
InitialDelay before verifying cleanup, and assert that all state for the removed
container remains absent, including scannedFiles. Fix ContainerCallback’s ticker
lifecycle so removing a container cancels the ticker and goroutine created when
it was added, rather than only stopping the remove callback’s ticker; ensure no
goroutine remains blocked and no state is recreated after removal.
- Around line 54-58: Handle and assert errors from both os.Unsetenv and the
deferred os.Setenv calls in the test setup around CLAMAV_SOCKET, using the
test’s existing failure mechanism so errcheck and golangci-lint pass.
In `@pkg/nodeprofilemanager/v1/nodeprofile_manager_test.go`:
- Around line 480-503: Update the HTTP handler in the sendProfile test to assert
that r.Method equals http.MethodPut, matching the configured
HTTPExporterConfig.Method value and ensuring sendProfile uses PUT rather than
another method.

Verify cleanup after the initial delay.
ContainerCallback creates a ticker for each callback. The remove callback stops its own ticker, not the ticker created by the add callback. After InitialDelay, the add callback recreates scannedFiles for the removed container. The remove callback also leaves its ticker goroutine blocked permanently.
This test checks only containerIdToPid before the add ticker fires. Wait through the configured delay, assert that all container state remains absent, and fix the lifecycle cancellation behavior.

Close the timer/removal race.
When InitialDelay expires during EventTypeRemoveContainer, both t.C and ctx.Done() can be ready. The select can choose the timer branch after scannedFiles.Delete, so scannedFiles.Set can recreate state for the removed container. Synchronize the timer callback with removal and add a test that removes a container at the delay boundary.

Resolves #913
Description
This PR introduces comprehensive unit tests for three previously untested manager packages:
malwaremanager,healthmanager, andnodeprofilemanager.These additions provide vital automated coverage around health probes, malware event handling, container lifecycle state, node profile generation, and profile reporting, making future modifications to these components much safer and easier to maintain.
