introduce next generation test suites - #2080
Conversation
WalkthroughThe enhancement defines hierarchical, label-driven OpenShift test suites using OTE APIs. It specifies suite membership, lifecycle-agent automation, shard balancing, validation, graduation, infrastructure requirements, and migration from legacy suite tags. ChangesHierarchical Test Suite Lifecycle
Estimated code review effort: 1 (Trivial) | ~5 minutes Merge Risk: 🟡 Moderate · up to The new test-suite rules can assign tests to the wrong lifecycle or execution-mode shard, or to multiple stable suites, while downstream minimal-suite membership and the active-job sample cadence remain undefined. These bounded correctness and readiness issues should be resolved or explicitly accepted before relying on the specification. Suggested reviewers: Sequence Diagram(s)sequenceDiagram

- Around line 117-123: Expand the “Promoting a Test to Blocking” policy to
define the pass-rate measurement window, minimum sample count, and how retries
and aborted runs are counted; also specify the required demotion or quarantine
action when a promoted blocking test regresses, rather than relying only on the
initial 2–3 sprint review.
- Around line 140-144: Update the post-GA + 1 Component Readiness stale-suite
rule so its 30-day threshold cannot flag a suite before the next monthly
spot-check run; either set the threshold above the maximum expected interval or
evaluate the flag only after a scheduled run.
- Around line 302-314: Update the “Infrastructure Needed” and related
acceptance-criteria sections to make the shadow CI jobs and Sippy queries
required dependencies, specifying an owner and availability gate for each;
alternatively, remove these validation requirements from the Test Plan and Dev
Preview → Tech Preview criteria. Apply the same change to the additional
referenced sections.
- Around line 295-300: Define an objective, repeatable rule for minimal-suite
membership before the graduation criterion in the surrounding proposal,
including explicit conditions for retaining tests in conformance/minimal versus
moving them to stable. Update the related migration, coverage-comparison, and
approval guidance to use this rule, and remove or resolve the corresponding open
question.
- Around line 125-132: Update the “Graduating a Test to Stable” protocol to
remove the old active-suite Parents advertisement before adding the stable-suite
advertisement, preventing dual membership across extension binaries. Require
parallel tests to use explicit suites such as openshift/stable-01 and serial
tests to use openshift/stable-serial-01; do not use the generic stable-NN form.
- Around line 217-224: Update the suite qualifier example to use the documented
test.labels.has("MY-FEATURE") contract instead of top-level labels.exists.
Define a stable-suite qualifier for each SHARD-NN value used by the shard
workflow, and enforce that every test belongs to exactly one stable shard suite.

Resolve minimal-suite membership before GA.
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.

Fantastic job on the enhancement, really lays out the plan simply. Key additions I'd like to see are an agent to handle the maintenance of tests and suites, and a number of edge cases and the plan for jobs.

|
|
||
| 1. After 2–3 sprints, the QSE engineer reviews the test's pass rate. |
There was a problem hiding this comment.
This really should be an agent, there's nothing here that can't be automated easily. We could do a prow job on a weekly or sprintly schedule, scan the informing tests, check the pass rate, submit the PR to remove it. This would keep QSE's out of the path from the get-go.

99.5% seems off here, it may just be component readiness at that point, and it would be holding a roughly 95% pass rate requirement. (assuming it was around 100 when it promoted, and our comp readiness parameters allow -5%)

| 3. During development, the spot-check job runs approximately 2x daily | ||

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.

Can go away, though PRs will have to be approved.
We have a developing need for PRs where teams have X days to respond, otherwise an architect or staff eng may merge it. This could be considered here, a PR to rebalance shards or promote tests does not really need team involvement.

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. I really think it's doable with precedent from stbenjam and co. It also closes the gap we have for informing tests getting left there forever, in both good and bad states.

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?

openshift-tests-extension Suite Qualifiers Parents suite membership semantics AddSuite test.labels.has
💡 Result:
In the openshift-tests-extension framework, AddSuite and suite qualifiers function as follows: AddSuite: The AddSuite method is used to register a new test suite within an extension [1]. When defining a suite, you can specify its Name, Qualifiers, and a Parents slice [1][2][3]. Suite Qualifiers: Qualifiers are defined using Common Expression Language (CEL) strings [4]. These expressions are used to filter which tests are included in a suite [1]. By default, qualifiers apply only to tests within the current extension, though Global Suites allow qualifiers to apply to all tests [1]. A common usage involves checking test names or labels, such as name.contains("[Serial]") or!labels.exists(l, l=="SLOW") [1][4][5]. Parents and Membership Semantics: The Parents field allows an extension suite to declare a relationship with existing OpenShift test suites (e.g., openshift/conformance/parallel) [6][7][8]. - Membership Semantics: When a parent suite is invoked, tests from the child suite are automatically included [1]. - Qualifier Propagation: The framework uses a fixed-point loop algorithm to merge child suite qualifiers into their parents, supporting arbitrary-depth transitive chains [6][8]. This ensures that when a parent (like openshift/conformance) is executed, it inherits the consolidated requirements and filters from all its children [6][8]. Note on test.labels.has: While standard labels exist, the framework predominantly utilizes CEL expressions on the test's name or its metadata properties [9][4]. If you encounter or are looking for a specific function like test.labels.has, ensure it is supported by the underlying CEL environment used by the current version of the extension framework, as many current implementations rely on explicit expressions like labels.exists(l, l=="...") or name.contains(...) [7][10][4].

💡 Result:
In the context of the openshift-tests-extension framework, Parents and Qualifiers are configuration properties used when defining test suites [1]. The openshift-tests-extension is a framework designed to allow external repositories to contribute tests to the OpenShift test suite through extension binaries [2]. Within this framework, suites are defined using the Suite struct [1]. Parents: This field takes a slice of strings representing the names of parent suites [1]. Specifying parents causes the tests within the defined suite to be included and executed when any of the listed parent suites are invoked [1]. Qualifiers: This field is a slice of strings that typically contains Common Expression Language (CEL) expressions [1]. These expressions are used to filter the tests composed within the suite [1]. By default, these qualifiers only apply to tests originating from the extension itself, unless defined as a global suite, in which case the qualifiers apply to all tests available [1].

Make shard qualifiers lifecycle- and mode-aware.
openshift/stable-01 and openshift/stable-02 select only SHARD-NN, while the centralized labelling code assigns one such label to every imported spec. OTE evaluates qualifiers across discovered specs and merges suite relationships additively. Therefore, an active or serial test can match a parallel stable suite, and the same test can match multiple stable suites. Graduation changes Parents, but rebalancing changes only the label, so membership can diverge from lifecycle and execution mode.
Define qualifiers that include lifecycle and execution mode, or make one field authoritative. Update all membership fields atomically. Add an OTE fixture covering active/stable, parallel/serial, and stable-01 to stable-02 transitions. Assert exactly one intended lifecycle and mode shard.
