Purpose

What this test checks

Checks dynamic status and asynchronous updates using TalkBack with Chrome on physical Android in the recorded android-talkback-chrome environment.

What this result means: This procedure records how TalkBack with Chrome on physical Android: Dynamic status and asynchronous updates behaves on android-talkback-chrome. It can expose evidence relevant to WCAG 4.1.3 for the tested task and environment. Use the linked conformance procedures for WCAG 4.1.3 to assess the complete requirements across the declared conformance scope.

Why it matters

Checks dynamic status and asynchronous updates using TalkBack with Chrome on physical Android in the recorded android-talkback-chrome environment. People most likely affected: blind people and others who use mobile speech output, touch exploration or sequential swipe navigation. A mobile screen-reader user may receive incomplete output, lose focus or be unable to complete the task. In the recorded android-talkback-chrome environment, check explore-by-touch, sequential swipes, rotor or local-context navigation, gestures and focus recovery; a gesture conflict or lost virtual focus can make the current screen unusable.

When to use it

Apply TalkBack with Chrome on physical Android: Dynamic status and asynchronous updates when a frozen critical task executed with the named mobile screen reader on physical hardware. The selected focus is Dynamic status and asynchronous updates.

Confirm before starting

Mark it not applicable only when

Exceptions

This platform, journey, usability or quality procedure creates no additional normative exception. Apply exceptions only in the linked atomic or criterion-level conformance procedure and preserve that separate decision.

Prepare

What you need

  • A physical supported phone or tablet is available; browser device emulation is prohibited for real mobile coverage.
  • The built-in screen reader and browser are updated to the recorded versions.
  • The tester has completed the vendor tutorial and is proficient with the configured gestures/rotor or reading controls.
  • The journey uses authorised synthetic or controlled client data.

Targets and required variations

  • The selected task, content and controls relevant to Dynamic status and asynchronous updates on the exact recorded physical device.
  • Default, revealed, loading, empty, validation error, interruption, recovery and confirmation where meaningful.
  • Every required environment, viewport, orientation, language and authenticated state recorded in the frozen scope.

Clean state

  • Complete a known-good calibration in the same environment before product testing.
  • Start from a recorded clean or known state and preserve any prior preferences, extensions, cache or profile settings that can affect output.

Assumptions: one short journey on one physical device and orientation; repeat supported orientations and materially different gesture paths

Variation: Add a new per-target execution and evidence allowance for each additional target class or state that could produce a different result. Add setup time for each distinct environment.

Excluded: Client coordination, inaccessible-environment recovery, recruitment, legal review, remediation implementation and waiting time unless the procedure states otherwise.

Execute

Test steps

Follow each action in order. The expected result is always visible; open the guidance when you need setup, tool, evidence, decision or repeat details. Step-level recording is optional while work is in progress and required only to export a completed execution.

Step 1

Prepare the scope, target and environment

Purpose: For TalkBack with Chrome on physical Android: Dynamic status and asynchronous updates, prepare the named scenario: Prepare the scope, target and environment. Target: The selected task, content and controls relevant to Dynamic status and asynchronous updates on the exact recorded physical device. The preparation must establish this result: The selected targets, states, test data, environment and any scope limitations are complete enough for another qualified tester to reproduce the setup.

User impact: A mobile screen-reader user may receive incomplete output, lose focus or be unable to complete the task. This scenario isolates that risk in the action named Prepare the scope, target and environment.

Before executing TalkBack with Chrome on physical Android: Dynamic status and asynchronous updates, freeze the product version and scope. Inventory each applicable target, select the required starting states, prepare safe test data and record every required environment value. Complete any named known-good calibration before attributing an observation to the product.

Expected result

The selected targets, states, test data, environment and any scope limitations are complete enough for another qualified tester to reproduce the setup.

Failure observation

During TalkBack with Chrome on physical Android: Dynamic status and asynchronous updates, the target, starting state, environment or scope record remains ambiguous for the scenario named Prepare the scope, target and environment. The preparation result cannot be demonstrated: The selected targets, states, test data, environment and any scope limitations are complete enough for another qualified tester to reproduce the setup.

Setup, evidence and decision guidance
Target
The selected task, content and controls relevant to Dynamic status and asynchronous updates on the exact recorded physical device.

Use the scope record and worksheet environment fields for TalkBack with Chrome on physical Android: Dynamic status and asynchronous updates: operating_system, operating_system_version, browser, browser_version, viewport_css_pixels, input_method, assistive_technology, assistive_technology_version, device_model, orientation.
Record
Scope/version reference; target inventory; starting states; safe-data reference; every required environment value; calibration result or reason it is not required.
Pass
Record passed for the TalkBack with Chrome on physical Android: Dynamic status and asynchronous updates scenario named Prepare the scope, target and environment only when the evidence (Scope/version reference; target inventory; starting states; safe-data reference; every required environment value; calibration result or reason it is not required.) supports: The selected targets, states, test data, environment and any scope limitations are complete enough for another qualified tester to reproduce the setup.
Fail
Record failed when the action is completed and this failure observation is reproduced: During TalkBack with Chrome on physical Android: Dynamic status and asynchronous updates, the target, starting state, environment or scope record remains ambiguous for the scenario named Prepare the scope, target and environment. The preparation result cannot be demonstrated: The selected targets, states, test data, environment and any scope limitations are complete enough for another qualified tester to reproduce the setup.
Not applicable
The frozen mobile scope contains no content, control or task relevant to Dynamic status and asynchronous updates.
Blocked
Record blocked, not passed, when An applicable target, required state, complete process or named real environment was not executed.
Repeat or recover
For TalkBack with Chrome on physical Android: Dynamic status and asynchronous updates, correct the setup gap, preserve the original blocked record and start a new execution observation before proceeding.
Limitations
This scenario records the action named Prepare the scope, target and environment for TalkBack with Chrome on physical Android: Dynamic status and asynchronous updates in android-talkback-chrome. It does not establish behaviour for another target, state or environment and does not set a WCAG conformance decision.
If you are new to this test
For TalkBack with Chrome on physical Android: Dynamic status and asynchronous updates, do not begin from an undocumented browser tab, document copy, device state, participant plan or evidence set. Record the exact item you will test first.
Record this step

Step 2

Trigger loading, search results, save success, errors and progress without moving focus

Purpose: For TalkBack with Chrome on physical Android: Dynamic status and asynchronous updates, execute the named scenario: Trigger loading, search results, save success, errors and progress without moving focus. Target: The selected task, content and controls relevant to Dynamic status and asynchronous updates on the exact recorded physical device. Compare the observation with this result: Important status changes are announced once, at the right time and without an unnecessary focus change.

User impact: A mobile screen-reader user may receive incomplete output, lose focus or be unable to complete the task. This scenario isolates that risk in the action named Trigger loading, search results, save success, errors and progress without moving focus.

Trigger loading, search results, save success, errors and progress without moving focus; record speech in sequence.

Expected result

Important status changes are announced once, at the right time and without an unnecessary focus change.

Failure observation

After the tester completes the TalkBack with Chrome on physical Android: Dynamic status and asynchronous updates scenario named Trigger loading, search results, save success, errors and progress without moving focus, the recorded observation for the target is inconsistent with the required result: Important status changes are announced once, at the right time and without an unnecessary focus change.

Setup, evidence and decision guidance
Target
The selected task, content and controls relevant to Dynamic status and asynchronous updates on the exact recorded physical device.
Required state
For TalkBack with Chrome on physical Android: Dynamic status and asynchronous updates, begin in the validation-error state immediately after submitting representative invalid input; preserve the exact content, account, platform and configuration used.
Tool or command

Blocked
Record blocked, not passed, when An applicable target, required state, complete process or named real environment was not executed.
Repeat or recover
Repeat in portrait and landscape where supported, capture displayed speech output or a contemporaneous transcript, and record every unreachable or misleading element. Repeat with touch exploration and sequential navigation in each required orientation, including validation, interruption and recovery states. Preserve the first TalkBack with Chrome on physical Android: Dynamic status and asynchronous updates observation when repeating.
Limitations
This scenario records the action named Trigger loading, search results, save success, errors and progress without moving focus for TalkBack with Chrome on physical Android: Dynamic status and asynchronous updates in android-talkback-chrome. It does not establish behaviour for another target, state or environment and does not set a WCAG conformance decision.
If you are new to this test
For TalkBack with Chrome on physical Android: Dynamic status and asynchronous updates: Use the platform gesture-practice area before testing. Keep one finger clear of unintended targets and record the focused item before and after every gesture.
Record this step

Step 3

Repeat material variations and recovery

Purpose: For TalkBack with Chrome on physical Android: Dynamic status and asynchronous updates, execute the named scenario: Repeat material variations and recovery. Target: The selected task, content and controls relevant to Dynamic status and asynchronous updates on the exact recorded physical device. Compare the observation with this result: Every material variation and required recovery path has its own reproducible observation; no unexecuted state is merged into a passing result.

User impact: A mobile screen-reader user may receive incomplete output, lose focus or be unable to complete the task. This scenario isolates that risk in the action named Repeat material variations and recovery.

Repeat the TalkBack with Chrome on physical Android: Dynamic status and asynchronous updates action for each inventoried variation that can change the outcome. Include relevant default, revealed, error, interruption, recovery and confirmation states and complete the selected process from start to finish where this test can affect task completion.

Expected result

Every material variation and required recovery path has its own reproducible observation; no unexecuted state is merged into a passing result.

Failure observation

After the tester completes the TalkBack with Chrome on physical Android: Dynamic status and asynchronous updates scenario named Repeat material variations and recovery, the recorded observation for the target is inconsistent with the required result: Every material variation and required recovery path has its own reproducible observation; no unexecuted state is merged into a passing result.

Decide

How to decide

Passed

Important status changes are announced once, at the right time and without an unnecessary focus change.

Failed

An applicable Dynamic status and asynchronous updates target has a reproducible material barrier against one or more stated expectations; identify the exact expectation, state and evidence.

Not applicable
The frozen mobile scope contains no content, control or task relevant to Dynamic status and asynchronous updates.
Cannot tell
The target is applicable, but conflicting evidence or unresolved responsibility prevents a defensible expectation decision after recorded comparison.
Not tested
An applicable target, required state, complete process or named real environment was not executed.
Aggregation and reporting boundaries

Aggregation: Preserve every target/environment outcome. Any failed target prevents an overall passed procedure result. cantTell and untested remain unresolved; inapplicable is valid only when the completed inventory contains no applicable target.

WCAG decision: This specialist, platform, document, usability or quality result does not set a WCAG success criterion to satisfied or not_satisfied automatically. Use linked atomic and criterion-level procedures for that separate decision.

Automation: A checker, accessibility-tree inspection, emulator or simulated assistive technology is diagnostic evidence only. Complete every required manual, real-platform, contextual and exception check.

Record

Record the result

Record the target, state and observed behaviour. Add evidence or technical details only when needed.

Choose the option that best matches what happened to this target.

Describe the actual behaviour and why it supports the selected result.

When more than one target is recorded, the overall procedure result is calculated from all target results.

Environment: Not set.
Add evidence or details

Choose only the group needed for this record. These fields remain optional for a working draft.

Evidence references

Enter one file name, issue ID or evidence reference per line. Files stay on your device.

Test environment

Save a named profile once to reuse the same product, platform and environment details on other procedures in this browser.

Engagement and tester identifiers

Assistive-technology execution confirmation

Use these statements only for work actually performed. Simulation or accessibility-tree inspection does not count as real assistive-technology coverage.

Formal completion and limitations

Identify the frozen list or sampling record used to select every target represented by this execution.

Choose a final result before marking the execution complete. Completed records require the full environment, step, evidence and method-specific information.

Data management

Export before clearing if the record must be retained. Apply the engagement retention schedule and delete browser data when it is no longer needed.

Saved drafts stay in this browser and are not uploaded. Do not enter credentials, secrets or unnecessary personal data.

Worked example and outcome calibration

A11Y-TBK-005-WORKED-001: representative worked example

Context: Representative synthetic example for TalkBack with Chrome on physical Android: Dynamic status and asynchronous updates on a fictional, version-frozen product target; no client or participant execution occurred.

Inspected: The tester follows S2 (Trigger loading, search results, save success, errors and progress without moving focus) using the target, required state, tool and repeat rule stated in this procedure.

Observed output: After the tester completes the TalkBack with Chrome on physical Android: Dynamic status and asynchronous updates scenario named Trigger loading, search results, save success, errors and progress without moving focus, the recorded observation for the target is inconsistent with the required result: Important status changes are announced once, at the right time and without an unnecessary focus change.

Evidence:

  • example-evidence-001: target and state record for The selected task, content and controls relevant to Dynamic status and asynchronous updates on the exact recorded physical device.
  • example-evidence-002: contemporaneous observation from the named method — Exact displayed speech or contemporaneous transcript with gesture, focus and state.
  • example-evidence-003: comparison note linking the actual observation to the expected result and claim boundary

Tester reasoning: The recorded observation does not demonstrate the expected result: Important status changes are announced once, at the right time and without an unnecessary focus change. The failed decision is limited to this synthetic target and state; unexecuted coverage is not inferred.

Decision: failed

Finding: A11Y-TBK-005-example-finding-001 — TalkBack with Chrome on physical Android: Dynamic status and asynchronous updates: expected result is not demonstrated. The represented barrier may affect Blind people and others who use mobile speech output, touch exploration or sequential swipe navigation.

Remediation: Change the represented target or process so it demonstrates this result: Important status changes are announced once, at the right time and without an unnecessary focus change. Then rerun the affected step and every dependent variation.

Reviewer feedback: The reviewer confirms applicability, environment, actual-versus-expected comparison, evidence references and bounded wording; unsupported product-wide or conformance language is removed.

Final client wording: Synthetic training finding: the sampled TalkBack with Chrome on physical Android: Dynamic status and asynchronous updates target does not meet the procedure expectation in the recorded state. User impact and broader scope require evidence from the buyer's real execution.

Retest: Synthetic retest example: after the represented change, repeat the failed step plus material error and recovery states. Close the finding only when new evidence demonstrates the expected result; otherwise retain the non-pass outcome.

Boundary: This is a representative, synthetic worked example for training and calibration. It is not evidence from a client product, participant or real assistive-technology execution.

Outcome calibration

Passed
In android-talkback-chrome, the selected Dynamic status and asynchronous updates target completes the recorded action and meets this expectation: Important status changes are announced once, at the right time and without an unnecessary focus change.

The example is a calibration scenario, not an execution or approval.

Failed
An applicable Dynamic status and asynchronous updates target produces a reproducible barrier during the named action, with the exact state and affected user task recorded.

A failed target remains failed even if another environment or target passes.

Not applicable
The frozen mobile scope contains no content, control or task relevant to Dynamic status and asynchronous updates.

Inapplicable requires a completed inventory showing that no target matches applicability; a missing environment is not inapplicable.

Cannot tell
The Dynamic status and asynchronous updates target is applicable, but conflicting product/platform evidence or missing authoritative information prevents a defensible responsibility or expectation decision.

Record the conflict, comparisons attempted and person or evidence needed to resolve it.

Not tested
The Dynamic status and asynchronous updates target is applicable, but a required state, complete process or real environment was not executed.

Untested remains incomplete and cannot be converted to passed or inapplicable.

Sampling, complete processes and platform limitations

Run each selected critical journey from start to finish, including its main error and recovery paths. Record which journeys and states were included.

If this check is part of a user journey, test the selected journey from start to finish, including relevant errors and recovery. Record any path that was not tested.

  • Physical-device evidence applies only to the recorded device, operating system, browser, screen-reader version and settings.
  • Check relevant browser, tool or assistive-technology release notes before assigning unexpected behaviour to the product.
  • If responsibility is unclear, record the reproducible behaviour and use cannot tell until it is resolved.
