Please merge!

Works around a pre-existing issue in OLM tests caused by roxies current handling of on-cluster manifests, persisting configuration values and poisining redeployments.

Summary by CodeRabbit

Tests

  • Expanded end-to-end coverage for deployment modes, including explicit OLM and non-OLM switching scenarios.
  • Test runs now begin with a clean cluster and consistently verify that deployments are removed afterward.
  • Improved validation across add-ons, custom registries, custom TLS certificates, mixed versions, port forwarding, and multi-component deployments.
  • No end-user functionality changes are included.

📝 Walkthrough

Changes

E2E cluster cleanup and OLM configuration

Layer / File(s) Summary
Centralize cluster cleanup
tests/e2e/helpers.go
Added ensureCleanCluster, which registers teardown and checks that Central, Sensor, and Operator deployments are absent. Removed the former cleanup helpers.
Adopt shared cleanup across E2E tests
tests/e2e/addons_test.go, tests/e2e/basic_test.go, tests/e2e/custom_registry_test.go, tests/e2e/custom_tls_test.go, tests/e2e/e2e_test.go, tests/e2e/mixed_versions_test.go
Tests now call ensureCleanCluster before execution. Local teardown and post-cleanup checks were removed where the shared helper replaces them. Port-forward teardown remains.
Make OLM switch modes explicit
tests/e2e/olm_switch_test.go
Non-OLM deployments now pass --olm=false. The secured-cluster command reorders its arguments and retains non-OLM verification. OLM switch tests use the shared cleanup setup.

Change: Bug fix

Suggested reviewers: vladbologa

Merge Risk: 🟡 Moderate · up to 08cf9

Cleanup can appear successful despite a teardown failure, and skipped OLM tests still modify the cluster. Fix both paths before merging.

Report teardown failures.

If either roxie teardown command fails, this callback discards the error. All Deployment checks can still pass when teardown leaves other resources behind. The test then reports successful cleanup, and a later test can encounter the leftover configuration. Assert the teardown error while retaining the Deployment checks.

Check SKIP_OLM_TESTS before registering cleanup.

When SKIP_OLM_TESTS is set, t.Skip still runs the cleanup registered on these four lines. Each skipped test therefore runs teardown commands and cluster checks without deploying anything. Move each skip guard above ensureCleanCluster(t) so skipped OLM tests do not modify the cluster or fail during unnecessary cleanup.

Also applies to: 87-87, 134-134, 210-210
