What is this about?

With testObservability: false and accessibility on, the Accessibility build stays in processing forever, even though the Automate sessions pass (SDK-7793, 7 of 7 customer builds on 1.36.20).

The CLI starts the TestHub build when observability or accessibility is on, but only stops it when observability is on.

Start: bin/commands/runs.js launches the TestHub build whenever shouldProcessEventForTesthub() is true, i.e. O11y || A11y (bin/testhub/utils.js).
Stop: printBuildLink() returns early unless it is an observability session, and it is the only caller of stopBuildUpstream(). stopBuildUpstream() also reads only the observability env vars (BS_TESTOPS_BUILD_COMPLETED / BS_TESTOPS_JWT / BS_TESTOPS_BUILD_HASHED_ID). An accessibility-only launch sets only BROWSERSTACK_TESTHUB_UUID / BROWSERSTACK_TESTHUB_JWT.

So an accessibility-only build is created at TestHub and never stopped, and TestHub never finalises it for Accessibility.

Wire capture on unpatched 1.37.1 (same config): POST /api/v2/builds → 200 with product_map {"observability":false,"accessibility":true}, then no PUT /api/v1/builds/<id>/stop for the rest of the run. The A11y build was still running 30+ min after the CLI exited.

Related Jira task/s

SDK-7793
A11Y-13549 (the PUT /api/test_runs/stop → 401 in the ticket comes from the BrowserStack-side runner, not the CLI; the CLI has no v2 A11y start path left)

Dependent PRs / release order

Dependent PRs: None. CLI-only, no paired change in railsApp / realMobile / binary.
No cross-repo deploy order applies.

Automation cases to add

Cypress case with testObservability: false + accessibility: true asserting the A11y build reaches completed after the run.

Code changes to check

Spread operator is not used.
Syntax supported by older Node: no ?. / ??.

The change

bin/testObservability/helper/helper.js

New isTestHubBuildLaunched(): true when BROWSERSTACK_TESTHUB_UUID and BROWSERSTACK_TESTHUB_JWT are both set to real values (not empty / "null" / "undefined").
printBuildLink() runs when it is an observability session or a TestHub build was launched.
stopBuildUpstream() stops the build when observability launched it or any TestHub build was launched. It uses the observability JWT/build id when observability launched the build and the TestHub ones otherwise. The observability path is unchanged.

test/unit/bin/testObservability/buildStop.js: 4 cases covering A11y-only stop, O11y stop, and no-build no-op.

Verification

Run	CLI	O11y	stop request	result
repro	unpatched 1.37.1	off	none sent	A11y build `u9snesxmqpfhdozauk7ygqdoljpt8gvc265dhjag` stuck `running`
fix	this branch	off	`PUT /api/v1/builds/whb8sz77rbcv2vyyghumlo7utfgakwiburvk1jn4/stop` → 200	A11y build `completed` (1 session, 37 issues)
fix, final rerun	this branch	off	stop → 200	`iaoyzxszgnsoqqegztjqs9dzdkmvcjqpdnx3rhr9` terminal
O11y regression	this branch	on	exactly one stop, as before	TRA build `cwvfokbl55id6w5g0epf9qbuk4u33m0n8vihoyai` `passed`, 1 passed / 0 failed

Unit: the new buildStop.js passes 4/4 on this branch and fails 2/4 on master. Full suite: 727 passing, 16 failing; the same 16 fail on master.

Not covered: async (non---sync) mode; 1.36.20 wire capture (TestHub launch returned 403 on our account; its source has the same gate).

Summary by CodeRabbit

Bug Fixes
- Build links and stop requests now work for valid TestHub builds, including accessibility-only builds. Stop requests use the correct build credentials and are sent only once.
- Stop requests are skipped when the required build details are missing or invalid.

Sorry, something went wrong.

          SDK-7793: stop TestHub build for accessibility-only runs

d986604

The TestHub build is launched when observability or accessibility is
enabled, but printBuildLink/stopBuildUpstream only ran for observability
sessions. Accessibility-only builds were never stopped, leaving the A11y
build stuck in processing. Stop the build whenever a TestHub build was
launched, using the TestHub JWT/UUID when observability did not launch it.

📝 Walkthrough

Walkthrough

The helper now recognizes valid TestHub builds and allows the stop flow to handle them. It selects the credentials and build ID from Test Observability or TestHub before sending the stop request. Unit tests cover both build types and related stop-request conditions.

Changes

TestHub build stopping

Layer / File(s)	Summary
Build detection and stop entry `bin/testObservability/helper/helper.js`	The helper checks whether both TestHub environment values are valid. `printBuildLink` continues when either Test Observability or TestHub is active.
Credential selection and stop request `bin/testObservability/helper/helper.js`, `test/unit/bin/testObservability/buildStop.js`	The helper selects the stop-request credentials and build ID based on the active build type. Tests cover both build types, missing TestHub values, and repeated calls.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Bug fix

Merge Risk: 🔵 Low · up to d9866

The accessibility-only stop flow uses the matching TestHub credentials. Remaining risk is limited to regression coverage; strengthen the validation and credential-selection tests.

58-59: 🎯 Functional Correctness | ⚡ Quick win

Use different TestHub credentials in the observability test.

Both credential sources contain the same values. This test still passes if stopBuildUpstream() incorrectly selects TestHub credentials when BS_TESTOPS_BUILD_COMPLETED is "true".

Set distinct TestHub values. Keep the assertions for the observability build ID and Authorization header.

Based on learnings, identity-sensitive tests must verify the fields that determine identity and authorization.

Cover independent credential-validation paths.

Add cases where each TestHub UUID or JWT is independently absent, empty, "null", or "undefined". Assert that no stop request is sent.

Use distinct TestHub and observability IDs and tokens. The current observability case cannot detect incorrect credential-source selection because both sources use identical values.

When BS_TESTOPS_BUILD_COMPLETED is "true", call stopBuildUpstream() with invalid observability credentials and assert status: 'error'.

The nodeRequest rejection and response.data.error branches are unchanged generic handling in stopBuildUpstream() and are outside this change-specific coverage.
