From 78af477ab80fd581495d3748caeb318e82fb3d4f Mon Sep 17 00:00:00 2001 From: Aaryan Choudhary Date: Thu, 22 Oct 2026 00:10:13 +0530 Subject: [PATCH 01/15] fix(app-automate): write a browserstack.yml the SDK reads as intended, with App Accessibility on request setupBrowserStackAppAutomateTests gains an `accessibility` input (default off) that writes `accessibility: true` with its options, for the Node WDIO config too. The platform version is now unquoted: SDK 1.51.x checks Android >= 11 with int(platformVersion), the string "14.0" throws, and the SDK then turns App Accessibility off without a message. browserstackLocal defaults to false, and the "// TODO" line, which YAML read as a key, is a "#" comment. With accessibility on, the output adds a step on what makes a scan happen (the driver must exist before the test starts; only interaction commands scan; Android 11+) and how to read the issues afterwards, with a pytest fixture for pytest projects.

A buildId is resolved on either API, the web Automated Tests API first, then App Accessibility, so the id the SDK prints as "testhub id" works as is; reportUrl also takes an App Accessibility build link, resolved through the project's build list. The tool waits while the build is running or rule_processing, as for web reports. The issues come inline from the build's scanned screens (the app API has no CSV export behind an access key): one row per element, most severe first, with the screen, rule, element details, fix, WCAG criteria and screenshot, paged by the same character cursor as web reports. The server already folds duplicates and leaves hidden issues out; the response says so, and links the report on the App Accessibility dashboard. A finished build with no scans gets the list of likely causes instead of an empty list. startAccessibilityScan now says it takes web pages and where a mobile app goes; the fetch tool's description and the handoff sentence mention app builds.

With `osVersion`, the documented key, it scans. Checked both ways on two devices: osVersion gave 3/36 (Pixel 8) and 2/24 (Galaxy S24) scans/issues; platformVersion gave 0/0 on both. The generator now writes osVersion, the setup step and the zero-scan checklist say so, and the Android-only wording becomes Android 11+ or iOS 14+, which is what the product supports. A build id that neither the web nor the App Accessibility API knows is now refused by resolveBuild, naming both, instead of falling through to the web export's error.

The fix can now be sized. - A page names each rule's name, description, WCAG criteria and usual fix, and each screen's screenshot, once, under `rules` and `screens`, instead of on every issue: two thirds of an issue's length. A 48-issue iOS build is read in 2 calls instead of 5.

Without it, platformVersion stays as before. - setupBrowserStackAppAutomateTests keeps main's description (268 chars); the accessibility argument describes itself. A new test holds every tool's description to 200 characters, or to its length on main if already longer. - A build lookup falls through to the other API only on 404 (both answer 404 for any id they do not know, checked live); a 401, 429 or 5xx is reported with its status instead of as "no such build". - A screen page that cannot be read fails the read with its page and status, rather than an unhandled error.

The Espresso and XCUITest build requests then carry `accessibility: true`, and the answer says how the issues are read once the build finishes: fetchAccessibilityIssues with the App Automate build link. Co-Authored-By: Claude Fable 5.1 * feat(accessibility): read App Automate build and session links fetchAccessibilityIssues maps an App Automate build or session link to the run's App Accessibility build. An SDK (Appium) run: any session of the build, then its test code, which carries the TestHub build id the results went to. A native (Espresso, XCUITest) run has no SDK session and the test-code route does not know its sessions, so it is found by name: the build's details name its project, the App Automate build list names the build, and App Accessibility lists the run under the same project and name. A run without accessibility on, a build with no sessions, or one too old for the newest pages each get a message saying so and what to pass instead. Co-Authored-By: Claude Fable 5.1 * test(accessibility): keep the server entry out of the registration test apiClient reaches src/index.ts through lib/utils, and the entry runs main() on import, which logs a missing-credentials error under vitest. Stub it as the other tests do. Co-Authored-By: Claude Fable 5.1 * feat(accessibility): list App Accessibility builds and reports, and read manual reports listAppAccessibilityReports lists what App Accessibility has on record, newest first, with the ids fetchAccessibilityIssues reads: a project's builds (and, without a project name, the projects, since a build list needs one), or the manual Workflow Analyzer reports. A project name matching none exactly names the near matches. fetchAccessibilityIssues reads a manual report by appReportId or its dashboard link. Its issues come inline from the report's scanned screens. The API lists every occurrence and does not mark the duplicates the dashboard folds, so the answer gives both the occurrences retrieved and the dashboard's own count. A report that has not ended reads as in_progress and is waited on like the other sources. Co-Authored-By: Claude Fable 5.1 * fix(accessibility): an empty listing is not an error The API answers an empty list with 404 ("No builds found", "No reports found") for access-key callers. listAppAccessibilityReports now reads that as "none" and says so, with what to drop or change; any other failure is still an error, with its status. Found by the isolated MCP evals: a name filter that matched nothing came back as "Request failed with status code 404". Co-Authored-By: Claude Fable 5.1 * fix(accessibility): keep the fetch prompt within the budget with appReportId added Co-Authored-By: Claude Fable 5.1 * test(accessibility): the app source is named by buildId's description, not the prompt Co-Authored-By: Claude Fable 5.1 * feat(server): say which product checks what for accessibility The tools alone do not tell an agent that a web page and a mobile app are scanned differently, so a request like "check my app for accessibility" could reach for Website Scanner, or for nothing. The server instructions now route it: a web page to Website Scanner, a multi-step web flow to Automate with accessibility on, an app to its tests on App Automate with accessibility on, then fetchAccessibilityIssues. A test keeps every tool the line names registered. Co-Authored-By: Claude Opus 5.5 * feat(accessibility): app build summary and comparison, exact paging, reliable build links - The first page of an app build or manual report counts its issues by severity, rule and screen, so an agent need not page through every issue to say where the problems are. - compareWith on an app build ("previous", or an earlier build's id or link) lists what is new, what was resolved and how many are still open, matching issues by rule and element (its id, or its class and text). It warns when the builds scanned different screens or ran different tests, as an issue on a screen not reached reads as resolved. "previous" is the newest earlier build of the same name, or the one just before it, as each native run is named apart. - "N more issues" is now exact on every page (it was estimated from the first row's size past page one), and a row larger than a page is still returned, so paging cannot stall on it. - An App Accessibility dashboard link is resolved by build name and number: numbers count up per build name, so a project's builds of different names share them, and the number alone could open another build. - An Espresso / XCUITest build link finds its accessibility build by the run's start, among the project's newest builds, rather than by walking the account's newest 300 App Automate builds for its name, which missed older runs. The name still tells apart runs that started together. Co-Authored-By: Claude Opus 5.5 * fix(accessibility): match look-alike app issues one for one when comparing builds An iOS issue often names its element by neither id nor class, only by a frame and sometimes an accessibility label, so every issue of one rule shared a match key: 40 font-size issues in one build and 9 in the next counted as one issue still open, and the counts no longer added up to either build's total. Issues that look alike are now paired one for one, those on the same screen and spot first, and the label tells unnamed elements apart. New and still open now add up to the later build's total, and resolved and still open to the earlier one's; the answer says so. Co-Authored-By: Claude Opus 5.5 * fix(accessibility): page a comparison's new and resolved issues with the cursor A comparison listed the first 50 new and 50 resolved issues and said how many more there were, but gave no way to read them: passing a cursor returned the same 50 (an eval read only 50 of 111 resolved issues). The cursor now counts the issues already listed, and the answer names the next one while either list has more. Co-Authored-By: Claude Opus 5.5 * fix(accessibility): address review on #505: native suites' setup, Test Observability, failed lookups - An Espresso build with accessibility on now also sends testObservability: true: Espresso's App Accessibility report is generated through Test Observability, and without it the build records no scans. - With accessibility on, the run-started answer names what the suite needs to be scanned: BrowserStack's Gradle plugin and SDK for Espresso, the embedded, initialized Swift SDK for XCUITest. - A native build that recorded no scans gets those causes, not the SDK's (browserstack.yml, driver fixture), which do not apply to it; the framework comes from the build's session_data. - A failed App Automate session lookup (401, 429, 5xx) is reported with its HTTP status instead of as "accessibility was not on for this run". Co-Authored-By: Claude Opus 5.5 * fix(accessibility): address review on #506: report id shape, empty listings, untrusted report names - appReportId must be a UUID, as a dashboard link's is: ".." would have sent an authenticated request to another API path. - A listing reads a 404 as empty only when the API says nothing was found ("No builds found", "No reports found"); a 404 from a wrong route or a missing permission is an error again instead of an empty list. - A manual report's name and link are quoted in an untrusted block, as build names now are. Co-Authored-By: Claude Opus 5.5 * fix(accessibility): address review on #511: build order, untrusted names, page limit - compareWith naming a build newer than the current one no longer reverses the result: the comparison runs from the earlier build to the later, and says so. - The compared builds' names and the names of tests not run again are quoted in untrusted blocks, as the build's own name now is. - "previous" no longer answers "first build" when it stopped at the page limit: it says the build, or the one before it, is beyond the newest builds read and asks for the earlier build's id or link; and when no same-name build was found within those pages it says so rather than that none exists. Co-Authored-By: Claude Opus 5.5 * docs(accessibility): keep the no-scans note's comment on its function Co-Authored-By: Claude Opus 5.5 * fix(accessibility): address review on #505: say what a native suite needs before it runs The accessibility flag's description and the tool's docs row name the instrumentation a native suite must be built with (Espresso: the Gradle plugin and Java SDK; XCUITest: the Swift SDK), so the agent can check before a run that would otherwise record no scans. Co-Authored-By: Claude Opus 5.5 * fix(accessibility): address review on #506: report a failed project search, say when the tool waits - A project search that fails (401, 403, 500) is reported as that failure, not as "No project named …", which sent the user to fix a name that was right. - docs/TOOLS.md says the tool waits for a finished run's report to process, and reads a run still in progress as it is. Co-Authored-By: Claude Opus 5.5 * fix(accessibility): address review on #511: failed build pages, native build identity - A page of a project's build list that fails is reported as the failure, on the first page or a later one, instead of ending the list, which made a build with earlier ones read as its project's first. - A native run is matched only to a build that can be native: an SDK suite (pytest, …) started at the same moment in the same project is no longer taken for it. Co-Authored-By: Claude Opus 5.5 * feat(accessibility): offer to write tests for an app that has none, in the user's framework The routing line sent a mobile app only to its existing tests. An app with no tests yet now has a path: the agent offers to write them, in the framework the user picks (Appium in any SDK language, Espresso or XCUITest), and picks one, saying which, if left to it. Co-Authored-By: Claude Opus 5.5 * feat(accessibility): read a manual report as the dashboard does, when its route takes the key A manual report's issues are read from the dashboard's own screens (app_scanner/:id/snapshot?hide_duplicate_issues=true) when that route takes the access key: the count is then the dashboard's, and each issue names its element, fix and measurements. Until it does (it answers a key with a login redirect today), they are read from the Manual Reports API as before, every occurrence, with the dashboard's count stated next to them. A manual report's page names each rule's text and each screen's screenshot once, as a build's does. Co-Authored-By: Claude Opus 5.5 * fix(accessibility): don't count issues on screens a later build didn't reach as resolved Screens are numbered by scan order, so comparing builds that scanned a different number of screens matched issues across them but read every issue on a screen the later build never reached as resolved: build #3 of an iOS app (3 screens) against #2 (5 screens) gave 111 resolved, 113 of the earlier issues sitting on the 2 screens #3 skipped. Screens are now recognised by the elements on them. When the builds scanned a different number of screens, issues on an earlier screen no later screen resembles are listed as not confirmed resolved, and issues on a later screen with no earlier counterpart as first scanned, not new. With as many screens in each build they correspond, and a screen with nothing left was fixed. The same comparison now reads 1 resolved, 113 not confirmed. Co-Authored-By: Claude Opus 5.5 * refactor(accessibility): list App Accessibility work through capabilities, not a tool The App Accessibility lists (the account's projects, a project's builds, manual reports) are documented access-key reads with nothing to add on top, which is what the capability registry is for. They ship as an `app_accessibility` product in capability/app_accessibility.capability-index.json, and listAppAccessibilityReports goes. - Three read capabilities, authored from the controllers: list_app_accessibility_projects, list_app_accessibility_builds and list_manual_app_accessibility_reports, on the project, build and manual_report entities. Routing terms (app accessibility, workflow analyzer, manual accessibility report, …) settle those questions on the product without asking; bare "accessibility" stays shared with TRA. - Guidance carries what the API does not say: the projects list reads `page` (not the documented `page_number`) and has no page-size ceiling; build_name only searches the 500 newest builds; an empty list answers 404; manual reports' `created_between` is echoed but never filters, and `user_id` applies to admins only, so neither is offered. - check-contract.py is clean, and every capability was invoked live through invokeCapability: projects, builds (plain and by name) and manual reports return what the index declares; the 404 and 400 answers match their guidance. - The manual-report and project-search messages point at the capability functions; the project search's error handling stays, tested on the native-build path that uses it. Co-Authored-By: Claude Opus 5.5 * test(accessibility): answer the project-search cases by URL, so the lookup order doesn't matter Co-Authored-By: Claude Opus 5.5 * fix: address review on #505: fail link lookups on their status, say what the run turns on From Savio's and Shreyas's review: - Mapping an App Automate link: the session list, the native build lookup and the build list now fail with their status on anything but a 404 (checked live: a native build lists no sessions, an unknown id is a 404 on each, a bad key 401). A 401 or 5xx no longer reads as "native build", "not an Espresso or XCUITest build" or "not among the newest builds". - An Espresso run with accessibility says it turns Test Observability on, which the build request does for Espresso's accessibility report. - runAppTestsOnBrowserStack keeps main's description (297 chars); the accessibility argument describes itself. Co-Authored-By: Claude Opus 5.5 * fix: address review on #506: read a manual report whole or say what is missing From Shreyas's review: - A dashboard screens page that fails after the first no longer returns the part read as the whole: the report is read from the Manual Reports API in full instead. - The Manual Reports API's issues pages fail with their page and status rather than counting fewer issues; the report lookup treats only a 404 as an unknown report (checked live: unknown id 404, bad key 401). - A report with more screens than the page limit says how many were read, as an App Automate build does. Co-Authored-By: Claude Opus 5.5 * fix: address review on #511: drop the server-wide routing text, tighten the compare From Savio's review: - The accessibility routing line in the server instructions is removed (every session paid for it, and it repeated what the tools' own descriptions say). The "offer to write tests" directive goes with it, pending a product call. From Shreyas's review: - A comparison refuses a build with more scanned screens than are read, as the issues on the rest would count as resolved or new. - Within one test, a screen that shares half of the smaller screen's elements with a screen of the other build is the same screen, so the fixes on a mostly fixed screen are resolved rather than "not confirmed". The sheet's builds (#2 and #3 of the iOS app) compare as before. - The build before a build: a build missing from its project's list, or a project not found by name, is an error rather than "its project's first". - A dashboard link whose name matches no build resolves to the one build with its number, and refuses to guess between several. Also: fetchAccessibilityIssues points at searchCapability for the app lists, and docs/TOOLS.md lists the three App Accessibility capabilities.
