WalkthroughThe PR adds option-based MOSC creation and shared OCB test environments. Extended OCB, MachineConfigNode, and OS image stream tests now use common setup, registry, Containerfile, pull-secret, image-expiration, validation, and cleanup helpers. ChangesMOSC and OCB test refactor
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to The refactor centralizes OCB test setup and cleanup, but some failure paths can leave MOSC resources active and cleanup errors are ignored, potentially contaminating or skipping later tests. Merge should wait for guaranteed cleanup and error handling. Sequence Diagram(s)sequenceDiagram

Check cleanup failures from DisableOCL.
Line 107 and Line 117 discard the error from DisableOCL. If MOSC cleanup fails, the test can continue with an active MOSC and leave resources for later tests. Assert the cleanup result or return the error to the caller.
Proposed fix
func (env *OCBTestEnv) Cleanup() {
if env.MOSC != nil {
- DisableOCL(env.MOSC)
+ o.Expect(DisableOCL(env.MOSC)).To(o.Succeed(), "Error cleaning up %s", env.MOSC)
}
if env.isCustomMCP && env.MCP != nil {
env.MCP.delete()
}
}
func (env *OCBTestEnv) CleanupMOSCOnly() {
if env.MOSC != nil {
- DisableOCL(env.MOSC)
+ o.Expect(DisableOCL(env.MOSC)).To(o.Succeed(), "Error cleaning up %s", env.MOSC)
}
}As per path instructions, **/*.go: Never ignore error returns.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win
Missing deferred MOSC cleanup when CleanupMCPOnly is used. Both tests create the MOSC through the shared environment but register only CleanupMCPOnly, and delete the MOSC inline later in the test body. If any assertion before that deletion fails, the MOSC survives, OCL stays enabled on the infra pool, secrets and the machine-os-builder deployment leak, and SkipTestIfOCBIsEnabled skips the remaining OCB tests in the same run.
