Apply the PMM version gate to every spec, not just the first one - #1201
Merged
Conversation
The gate added in #1184 registers pmmTest.beforeEach at module scope in fixtures/pmmTest.ts. The module is evaluated once, when the first spec file that imports it is loaded, so Playwright attaches the hook to that one file's root suite; every other spec runs ungated. In the RC Testing Suite run on 3.9.1 the hook landed on tests/inventory/services.test.ts (no gated ids), so PMM-T2265/T2266/T2267 ran against a server that does not have the feature -- percona/pmm#5537 is reverted on the pmm-3.9.1 branch (6d729c8). Move the check into an auto fixture, which applies to every test regardless of which file loads first, and memoize the version lookup so the endpoint is hit once per worker process instead of once per gated test. Tests whose id is not in minPmmVersion make no request at all. The fixture depends on request rather than api so it does not pull a browser page into tests that never open one.

The Playwright PMM-T2029 opens MySQL Replication Summary and picks a value in the Environment variable, added by percona/pmm#5647 (PMM-13932). That PR is reverted on the pmm-3.9.1 branch (6edca30), where the variable is still hide: 2, so the picker is never rendered and the test times out on selectVariableValue('Environment', ...). Same class as the entries already in the list, so gate it the same way. Signed-off-by: travagliad <215686151+travagliad@users.noreply.github.com>
Review feedback: getServerVersion cached the promise itself, so a transient failure of /v1/version was sticky -- every gated test in that worker would reuse the rejection instead of retrying. Clear the cache from the rejection path and rethrow, which keeps sharing intact for the in-flight and successful cases. Signed-off-by: travagliad <215686151+travagliad@users.noreply.github.com>

pmm-3.9.1tip but was reverted on that branch. The first five are already inminPmmVersionat3.10.0and should have been skipped — the gate never runs for them. PMM-T2029 was missing from the list.The gate only ever covered one file
fixtures/pmmTest.tsregisters the check as a module-scope hook:The module is evaluated once — while the first spec file that imports it is being loaded — and Playwright attaches the hook to that file's root suite. Every other spec file gets no gate.
Verified in this repo with two throwaway specs importing
@fixtures/pmmTest, onmain(hook body replaced with a log line so the browser dependency doesn't mask it):Running
bSession.test.tson its own does get the hook, so which file it lands on is just load order — it is not stable across runs or worker restarts.That matches the CI run exactly: the gate commit (
1b66224) is an ancestor of the run's SHA (b8f6c3b),versionGates.tsat that SHA listsPMM-T2265: '3.10.0', the server reportedVersion: 3.9.1, and there is noRequires PMM Server 3.10.0+anywhere in any job log — every gated test ran. In the@rtajob the hook had landed ontests/inventory/services.test.ts(PMM-T2159, not gated), so nothing was gated at all.Change
Move the check into an auto fixture, which applies to every test regardless of load order, and memoize the version lookup:
helpers/version.helper.ts—getServerVersion()caches the promise, so it is one request per worker process rather than one per gated test, and concurrent tests in a worker share the in-flight call.fixtures/pmmTest.ts—versionGateauto fixture; tests whose id is not inminPmmVersionmake no request at all. It depends onrequestrather thanapiso it does not pull a browserpageinto tests that never open one (the old hook did, viaapi: ({ page, request })).api/server.api.ts— exportPmmVersionso the helper can type the cache.helpers/versionGates.ts— addPMM-T2029. It callsdashboard.selectVariableValue('Environment', …)on MySQL Replication Summary; the Environment picker comes from percona/pmm#5647 (PMM-13932), reverted onpmm-3.9.1(6edca30), where the variable is stillhide: 2and never renders. Same class as the entries already there.The existing
3.10.0values are otherwise left alone — they are correct. percona/pmm#5537 (RTA URL state), #5694 (update-popup snooze, PMM-T2263) and #5636 (MongoDB Unused Indexes, reached via the PMM-T2202 menu walk) are all reverted onpmm-3.9.1(6d729c8,949bd7a,7a17a2a).Verification
Same two throwaway specs, this time with the real fixture and a stub server on
/v1/versionreturning3.9.1:Both gated tests skip, in both files; the ungated test triggers no request. The probe specs were removed before committing.
npx tsc --noEmitandnpx eslintclean on the changed files. What this cannot prove locally is the real suite against a real server — the next RC/nightly run is what confirms these tests skip on 3.9.x and still run on 3.10.Confirmed live on a real 3.9.1 server
The nightly added above is the same defect, observed end to end on a throwaway Linode VM running
perconalab/pmm-server:3-dev-latestat digestsha256:2cf5b658…— byte-identical to the image the failingnightly used — with
pmm-framework --database psmdb,OL_VERSION=8,GSSAPI=true. The server reports3.9.1-v3-cbf31f02a, andPMM-T2268is already listed inversionGates.tsat3.10.0:Run alone the spec is the first file loaded, so it gets the hook and skips; in the suite the hook landed
elsewhere and it ran against 3.9.1. That is this PR's bug reproduced directly against a real server rather than
a stub, and it is why the auto fixture is the right shape — no change to
versionGates.tsis needed forPMM-T2268.
Worth recording separately, since it is what made this particular spec go red on 3.9.1 tonight rather than pass
as it had on previous nights:
PMM-T2268asserts a second pagination page exists after filtering QAN storedmetrics to
service_type=mongodb, and the QAN page size is 25 (DEFAULT_PAGE_SIZEinpmm-app/src/pmm-qan/panel/QueryAnalytics.constants.ts). On the freshly provisioned VM that filter returned17 query groups right after setup and 33 about five minutes later. The growth is not test-generated —
every
simulateLongRunningQuerycall collapses into the single fingerprintdb.test.find({"$where":"?"}). It isbackground chatter accumulating distinct fingerprints over time: PBM agent polling (
pbmCmd,pbmConfig,pbmAgents,pbmBackups), exporter$collStats/$indexStats/dbStats/$currentOp, and oplog reads — with.batchSize(1)variants counting as separate groups and appearing minutes apart. So the spec only has a page 2once the environment has been up long enough. That is latent and will still be true on 3.10; it is out of scope
here and not worth a change while the gate keeps the spec off 3.9.x.
