introduce next generation test suites - #2080
Conversation
WalkthroughThe enhancement proposes hierarchical, label-driven OpenShift test suites using OTE APIs. It defines suite lifecycles, explicit sharding, Sippy balancing, validation criteria, and migration steps from flat string tags. ChangesHierarchical Test Suite Proposal
Estimated code review effort: 1 (Trivial) | ~5 minutes Merge Risk: 🟡 Moderate · up to This change defines new test-suite promotion and graduation behavior, but key rules for membership, labeling, regression handling, validation dependencies, and stale detection remain ambiguous.

Define the pass-rate calculation and regression action.
The proposal does not define the measurement window, minimum sample count, treatment of retries or aborted runs, or action when a blocking test regresses. A one-time review after 2–3 sprints can promote a test that later becomes flaky and remains blocking. Define the calculation and a demotion or quarantine rule.

Make promotion exclusive and preserve execution topology.
OTE merges Parents additively across extension binaries. If old and new advertisements coexist, changing openshift/active-01 to openshift/stable-01 leaves the feature in both suites. Define a rollout protocol that prevents dual membership. Map parallel and serial tests to explicit stable suites, including openshift/stable-serial-01, instead of using stable-NN.

Align the stale-suite threshold with the monthly cadence.
After GA + 1, the job runs approximately once per month, but the readiness flag triggers after 30 days without a pass. A normally scheduled run can therefore trigger a stale flag before it executes. Set the threshold above the maximum expected interval or evaluate the flag after a scheduled run.

Define the label-to-suite and shard-membership contract.
Use test.labels.has("MY-FEATURE"). The proposal uses undocumented top-level labels.exists(...), which can produce an empty suite.
The shard workflow changes SHARD-NN labels, but no stable-suite qualifier consumes them. Define one qualifier per stable shard and enforce exclusive shard membership.

The open question at Line 297 blocks the graduation criterion at Line 328. The proposal does not define an objective rule for keeping a test in conformance/minimal versus moving it to stable. Without that rule, migration tooling, coverage comparison, and approval decisions cannot produce repeatable results.

| ## Test Plan | ||
|
|
||
| This enhancement is about test infrastructure organization rather | ||
| than product functionality. Validation will consist of: | ||
|
|
||
| - Verifying that the OTE APIs correctly compose the new suite | ||
| hierarchy. | ||
| - Confirming that suite membership via CEL qualifiers produces the | ||
| expected test lists. | ||
| - Validating that the `Informing()` lifecycle correctly gates test | ||
| blocking status. | ||
| - Running the new suite hierarchy in a shadow CI configuration | ||
| alongside existing suites to compare coverage and runtime. |

etcd-scaling preferred to keep it once a week, and there will hopefully one day be an automatic retries mechanism if it fails. This is ok as written though, the schedule would likely be 1x a month still.

Could the enhancement call out how we can automate locating tests? I think there's a piece of work here hopefully TRT could take which is a more robust test database, which knows where the source code is. This would give us a central index to scan for tests that are informing or due for promotion, which we have already, but we don't necessarily know where they live.

I think this would be so time consuming to do today manually it would never happen, we should just skip that phase and go straight to the agent from the get-go.

And yet another, could we discuss how and where the jobs will be used, and potential cost concerns or improvements. I was envisioning that minimal is used on prs and payloads. Active and stable regressions are caught in component readiness. (I'm a little more flexible on active, maybe that goes to payloads as well)
I don't see any path through this where cost is lowered, but I'm not sure. The most commonly run jobs will be minimal, they'll be shorter and faster. Active will run less often, and stable even less than active. The 40 min overhead of getting a cluster though may negate the savings, but I'm really not sure.

And another (sorry), could you spell out the plan for jobs, what happens to the jobs that exist today, such as aws-ovn, aws-ovn-upgrade, aws-ovn-serial. What suite will these be running? Will jobs need to be mass renamed?
