test(e2e): serve the v2 catalog routes from the mock server - #37
brentyates-swx wants to merge 5 commits into
Conversation
mock-server.ts implemented the v1 `/provider` route and about twenty other
`/api/*` routes, but never `/api/provider`, `/api/model` or
`/api/model/default`. Those fell through to the catch-all that returns `{}`,
so `providers.data` was undefined and normalizeProviderList threw
Cannot read properties of undefined (reading 'all')
on every spec declaring `protocol: "v2"` that boots a project. The app caught
it in loadProvidersQuery's handler and raised a "Failed to reload" toast, so
the review panel rendered its diff but its interaction layer never came up:
`hover()` landed and `data-hovered` was never set.
Measured, not inferred: 1251 of 1251 responses to those three endpoints came
back `200 {}`. It is a constant for affected specs, not an intermittent race.
The new routes derive from the same `config.provider` the v1 route serves, so
a spec configures providers once and both protocols agree.

The first version of this fix removed the "reading 'all'" crash for specs with an empty provider list, and introduced a different one for the four v2 specs that define models: undefined is not an object (evaluating 'model.time.released') normalizeProviderList reads model.time.released, model.variants.map and cost.cache unconditionally, so a partially-shaped model throws inside the app rather than failing a route. CI stayed green because those specs do not assert on provider state -- they simply swallowed the toast, which is exactly how the original bug hid. Derives the full model shape, and adds a unit test that feeds the mock's derived catalog through the real normaliser for each provider shape the specs actually use. Verified by mutation: dropping `time` fails 2 of the 5 tests, and pinning `variants` to [] fails the variants test. Refs #26 Claude-Session: https://claude.ai/code/session_017iG7xA9wRvNyFYZSXm8inU
Correction pushed — the first commit was an incomplete fixReviewing my own change before marking it ready, I found it was the same defect class it was fixing.
Tested directly rather than inferred — fed the derived catalog through the real normaliser and watched it throw. CI was green anyway. Those specs don't assert on provider state, so they swallowed the toast and passed — which is precisely how the original bug stayed invisible for so long. A green run on this change did not mean the change was correct. What changed
Verified by mutation, not just by passing
That matters here specifically, because the thing that made this bug survive was a test suite that passed while the app was broken underneath. A test asserting the route returns 200 would have proved nothing; this one asserts the payload is something the consumer can actually use.

The test imported e2e/utils/mock-server.ts from under src/, which the app's tsconfig does not include, so `bun run typecheck` failed with TS6307 and the pre-push hook rejected the push. Caught by the hook, not by me. Moves it beside the code it tests, following the precedent of the other bun tests under e2e/ (test:stability, test:bench), and extends test:unit to cover e2e/utils so CI actually runs it -- a test CI never executes is not a regression guard.

Correction to the comment aboveThat comment said the fix was pushed. It was not — the push had just been rejected by the pre-push hook, and my command ended in an unconditional Two things the hook caught that I had already called clean: I verified the wrong scope. I said "typecheck clean" on the strength of ...plus a real type error where the variants assertion indexed a possibly-undefined Fixed by moving the test to where it belongs,
Nothing about the substance changed: the derivation still supplies the full model contract and the mutation results still hold (drop |
Moving the test under e2e/ put it inside Playwright's testDir. Playwright runs under Node, whose ESM loader rejects `bun:test`: Error: Only URLs with a scheme in: file, data, and node are supported by the default ESM loader. Received protocol 'bun:' That failed the whole e2e job in 69s, before a single spec ran. The existing bun tests under e2e/performance avoid this via testIgnore; this extends the same exclusion to the helper tests. Verified by collection rather than by reasoning: `playwright test --list` reports 105 tests in 42 files with mock-catalog absent, matching CI's count, and `bun test ./e2e/utils` still runs the 5 catalog tests.

Cross-model review (sol) found three real defects in the previous commits. All three are confirmed, not taken on trust. 1. typecheck:e2e was broken. Moving the test under e2e/ reversed the TS6307 dependency direction rather than resolving it: the e2e project could not see src/context/global-sync/utils.ts or its path-key dependency. Nothing caught it because CI runs `bun typecheck` -> turbo -> `tsgo -b`, and the app tsconfig includes only ./src, so the e2e project is never typechecked there. Fixed by listing the two files in e2e/tsconfig.json, which is how this project already pulls in ../src/pages/session/timeline/ observe-element-offset.ts. 2. The derived payload was not a possible server response. `time.released` is a number in the contract and emitted an ISO string; `status`, `enabled` and `limit.output` are required and were absent; ProviderV2Info requires `package`. normalizeProviderList tolerated all of it, so the specs passed over fiction -- the "green mock, broken product" trap. The helper's return is now typed as ProviderListOutput/ModelListOutput/ ModelDefaultOutput, so this class of error is a compile failure instead of a silent one. 3. The test asserted the helper, not the routes. Deleting or renaming all three routes -- the original bug -- would have left every test green. Added route-level tests that drive the real handler through a stub page. Verified by mutation: emitting a string `released`, dropping `status`, and dropping `limit.output` each fail a test; deleting the three routes fails 4. typecheck:e2e clean, full typecheck 30/30, playwright still collects 105 tests in 42 files with the bun test excluded.

Review response — three defects found, all confirmed and fixedCross-model review (sol) found three real problems. I verified each myself rather than acting on the report, and all three were right. Deferred items are filed as #39. 1.

|---|---|---|
time.released |
number |
ISO string "1970-01-01" |
status |
"alpha"|"beta"|"deprecated"|"active" |
undefined |

normalizeProviderList tolerates every one of those, so the specs passed over a fiction — the "green mock, broken product" trap I asked the reviewer to look for, in my own change.
Fixed at the root: the helper's return is now typed as ProviderListOutput / ModelListOutput / ModelDefaultOutput, so a wrong shape is a compile error rather than something the normaliser quietly absorbs.
3. The test did not cover the routes
True by construction — it called providerCatalog() directly, so deleting or renaming all three routes, which is the original bug, would have left every test green. Added route-level tests that drive the real handler through a stub page, no browser needed.
Verified by mutation

Deferred to #39
Availability filtering (connected/disabled are ignored where the server returns available()), default-selection-by-release-time, the provider payload being minimal against the current workspace schema, the legacy object-shaped capabilities case, and the client/server route skew the review surfaced — the app's pinned client exposes /api/model/default while the current server no longer does. No current spec depends on any of it, and none belongs in a bug fix.

Closing unmerged, by decision on scope. This fix is correct and verified — the mock genuinely had no v2 catalog routes, the payload is now contract-typed, and the route-level tests catch deletion. But it is the wrong shape for this fork. It adds divergence across 5 files inside The benefit — our e2e no longer failing on What is preservedThe full diagnosis stays on #26: Also recorded, because it is real and independent of this PR: CI never typechecks the e2e project. |
packages/app/e2e is upstream's suite and this fork does not maintain it, so its flake should not block our feature work. #26 documents the known failure: the mock server has no v2 catalog routes, so every protocol:"v2" spec that boots a project runs against a crashed provider bootstrap, and review-line-comment fails all three attempts whenever timing lines up. Fixing that properly meant five files of divergence inside packages/app/e2e (see the closed #37). This fork already carries 62 CI/test-infrastructure files of divergence against 46 product files, which is the friction that makes every resync with upstream more expensive. One line in a workflow we already own entirely is the cheaper trade. The suite still runs and still uploads artifacts, so the signal is kept -- a failure now annotates the run instead of blocking it. Also updates the pinned test.yml::e2e digest in check-workflow-guards.ts, since changing the job necessarily changes it. The audit is green at 3/3.

The defect
packages/app/e2e/utils/mock-server.tsimplements the v1/providerroute and about twenty other/api/*routes, but never/api/provider,/api/modelor/api/model/default. Those fall through to the catch-all at the bottom of the handler that returns{}.So for every spec declaring
protocol: "v2"that boots a project,sdk.provider.list()resolves with200 {},providers.dataisundefined, andnormalizeProviderListthrows:loadProvidersQuery's handler catches it and raises a "Failed to reload " toast. The visible consequence is subtler than the toast: the review panel renders its diff, but its interaction layer never comes up.hover()lands fine anddata-hoveredis never set — which is how this presented in CI onreview-line-comment.spec.ts:48, with the element resolving and staying stable across 33 polls over 30 s.Measured, not inferred
Instrumented the spec to log every provider/model response:
1251 of 1251. This is a constant for affected specs, not an intermittent race — which also corrected my own earlier reading of #26, where I had treated the toast as the thing distinguishing a failing run from a passing one. It isn't; it is always there.
The fix
Three routes, deriving from the same
config.providerthe v1 route already serves, so a spec configures providers once and both protocols agree./api/providerreturns the provider array,/api/modelthe flattened model list,/api/model/defaultthe configured default, each in the{ location, data }envelope the neighbouring v2 routes use.bunx tsgo -p e2e/tsconfig.jsonis clean, and thereading 'all'error is gone from the run (0 occurrences, from 1251).What this does NOT claim
It is not established that this reduces flakiness. I tried to A/B it locally and the numbers are void: this machine was at load average 90 from other sessions, which turned a 30-test run into 7 tests in 17.4 minutes and exited non-zero. Anything I measured there describes the box, not the code. For the same reason, an earlier "28 of 88 specs flaky" figure I quoted on #26 is withdrawn — that was the same contended machine.
CI on a dedicated runner is the only place that comparison means anything, so I am deliberately letting this PR's own e2e run be the first real datapoint rather than asserting an improvement.
What is defensible without any flake argument: the app expects a catalog, the mock returned an empty object, and every affected spec has been running against a permanently failed provider bootstrap. That is worth fixing on its own.
