Purpose

What this test checks

Changing a component setting unexpectedly changes context without prior advice.

What this result means: This WCAG 3.2.2 On Input procedure determines whether the recorded targets meet WCAG 3.2.2 on web-desktop-cross-browser in the tested states. A broader conformance decision must also account for every applicable target in the declared scope, complete processes, accessibility-supported use and the other WCAG conformance requirements.

Why it matters

Changing a component setting unexpectedly changes context without prior advice. People most likely affected: people who use keyboards, switches, speech input or adapted pointing devices; Blind people and people using screen readers or braille; People with cognitive, language, learning or memory disabilities. Users may lose context, data or control while entering information. In the recorded web-desktop-cross-browser environment, apply the criterion to every relevant state and named normative exception; failures in critical tasks and complete processes carry the greatest user impact.

When to use it

Change the setting without an explicit submit/activation and verify prior advice where a context change occurs.

Confirm before starting

Mark it not applicable only when

Exceptions

Prior advice

Decision condition
The user is advised before using the component that changing its setting causes the context change.
Evidence needed
Instruction text, timing and component relationship.
Common error
A message after the change is too late.
Scope
Only that component behaviour.

Prepare

What you need

  • The product area and test targets are agreed before testing starts.
  • The operating system, browser, viewport and input method are recorded.
  • Test data is safe to use and does not expose unnecessary personal information.

Targets and required variations

  • Each setting change in a user-interface component that can automatically change context.
  • Default and every meaningful state or variation that can change the result.

Clean state

  • Start from a documented clean or known state and record pre-existing preferences, extensions and cached data that can change the result.

Assumptions: one page or component state; add another execution block for each materially different template or state

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

Inventory applicable targets

Purpose: For WCAG 3.2.2 On Input, prepare the named scenario: Inventory applicable targets. Target: Each setting change in a user-interface component that can automatically change context. The preparation must establish this result: Every selected target and state is uniquely identifiable before testing.

User impact: Users may lose context, data or control while entering information. This scenario isolates that risk in the action named Inventory applicable targets.

Freeze the page, content and product version. Inventory Each setting change in a user-interface component that can automatically change context. Apply this rule: Change the setting without an explicit submit/activation and verify prior advice where a context change occurs.

Expected result

Every selected target and state is uniquely identifiable before testing.

Failure observation

During WCAG 3.2.2 On Input, the target, starting state, environment or scope record remains ambiguous for the scenario named Inventory applicable targets. The preparation result cannot be demonstrated: Every selected target and state is uniquely identifiable before testing.

Setup, evidence and decision guidance
Target
Each setting change in a user-interface component that can automatically change context.
Required state
For WCAG 3.2.2 Warn before context changes caused by input, use default and every meaningful state or variation that can change the result.
Tool or command
For WCAG 3.2.2, use the frozen scope inventory, product requirements and rendered content to identify every Warn before context changes caused by input target.
Record
Page/view, target identifier, state, technology, sample rationale and scope limitation.
Pass
Record passed for the WCAG 3.2.2 On Input scenario named Inventory applicable targets only when the evidence (Page/view, target identifier, state, technology, sample rationale and scope limitation.) supports: Every selected target and state is uniquely identifiable before testing.
Fail
Record failed when the action is completed and this failure observation is reproduced: During WCAG 3.2.2 On Input, the target, starting state, environment or scope record remains ambiguous for the scenario named Inventory applicable targets. The preparation result cannot be demonstrated: Every selected target and state is uniquely identifiable before testing.
Not applicable
The completed scope inventory contains no target matching: Each setting change in a user-interface component that can automatically change context.
Blocked
Record blocked, not passed, when The target is applicable, but a required action, state, environment or evidence item was not completed.
Repeat or recover
Repeat the WCAG 3.2.2 target inventory after a material content, state, technology or process change.
Limitations
This WCAG 3.2.2 On Input scenario covers only the action named Inventory applicable targets for the recorded target and state. It contributes evidence to 3.2.2; apply the procedure's aggregation, complete-process and conformance-scope rules before making a broader decision.
If you are new to this test
For WCAG 3.2.2, keep agreed scope exclusions separate from the target's applicable, inapplicable and pass outcomes.
Record this step

Step 2

Warn before context changes caused by input

Purpose: For WCAG 3.2.2 On Input, execute the named scenario: Warn before context changes caused by input. Target: Each setting change in a user-interface component that can automatically change context. Compare the observation with this result: Changing a setting does not automatically change context unless users were advised before using the component.

User impact: Users may lose context, data or control while entering information. This scenario isolates that risk in the action named Warn before context changes caused by input.

Change each form control value without an explicit submit action and observe context changes; verify advance warning where a change is expected.

Expected result

Changing a setting does not automatically change context unless users were advised before using the component.

Failure observation

After the tester completes the WCAG 3.2.2 On Input scenario named Warn before context changes caused by input, the recorded observation for the target is inconsistent with the required result: Changing a setting does not automatically change context unless users were advised before using the component.

Setup, evidence and decision guidance
Target
Each setting change in a user-interface component that can automatically change context.
Required state
For WCAG 3.2.2 Warn before context changes caused by input, use default and every meaningful state or variation that can change the result.
Tool or command
Keyboard and pointer input with route, window, focus and submission observation.
Record
Component/setting, prior advice, action, resulting context and focus/data effect.
Pass
Record passed for the WCAG 3.2.2 On Input scenario named Warn before context changes caused by input only when the evidence (Component/setting, prior advice, action, resulting context and focus/data effect.) supports: Changing a setting does not automatically change context unless users were advised before using the component.
Fail
Record failed when the action is completed and this failure observation is reproduced: After the tester completes the WCAG 3.2.2 On Input scenario named Warn before context changes caused by input, the recorded observation for the target is inconsistent with the required result: Changing a setting does not automatically change context unless users were advised before using the component.
Not applicable
The completed scope inventory contains no target matching: Each setting change in a user-interface component that can automatically change context.
Blocked
Record blocked, not passed, when The target is applicable, but a required action, state, environment or evidence item was not completed.
Repeat or recover
Repeat the WCAG 3.2.2 action when the target's content, state, environment or underlying technology changes.
Limitations
This WCAG 3.2.2 On Input scenario covers only the action named Warn before context changes caused by input for the recorded target and state. It contributes evidence to 3.2.2; apply the procedure's aggregation, complete-process and conformance-scope rules before making a broader decision.
If you are new to this test
For WCAG 3.2.2 Warn before context changes caused by input, record the actual evidence before deciding; use checker or visual evidence alone only when this procedure defines it as the measurement.
Record this step

Step 3

Repeat material variations and recovery

Purpose: For WCAG 3.2.2 On Input, execute the named scenario: Repeat material variations and recovery. Target: Each setting change in a user-interface component that can automatically change context. 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: Users may lose context, data or control while entering information. This scenario isolates that risk in the action named Repeat material variations and recovery.

Repeat the WCAG 3.2.2 On Input 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 WCAG 3.2.2 On Input 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.

Setup, evidence and decision guidance
Target
Each setting change in a user-interface component that can automatically change context.
Required state
For WCAG 3.2.2 On Input: Default and every meaningful state or variation that can change the result.
Tool or command
For WCAG 3.2.2 On Input, use the same recorded method, then change only the state, environment or recovery condition being compared.
Record
Variation identifier; changed state or environment; start and end points; actual observation; recovery result; intervention; evidence reference and target outcome.
Pass
Record passed for the WCAG 3.2.2 On Input scenario named Repeat material variations and recovery only when the evidence (Variation identifier; changed state or environment; start and end points; actual observation; recovery result; intervention; evidence reference and target outcome.) supports: Every material variation and required recovery path has its own reproducible observation; no unexecuted state is merged into a passing result.
Fail
Record failed when the action is completed and this failure observation is reproduced: After the tester completes the WCAG 3.2.2 On Input 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.
Not applicable
The completed scope inventory contains no target matching: Each setting change in a user-interface component that can automatically change context.
Blocked
Record blocked, not passed, when The target is applicable, but a required action, state, environment or evidence item was not completed.
Repeat or recover
Repeat this action for every required variation of Warn before context changes caused by input and after a material target, content, state, environment or configuration change. Preserve the original observation.
Limitations
This WCAG 3.2.2 On Input scenario covers only the action named Repeat material variations and recovery for the recorded target and state. It contributes evidence to 3.2.2; apply the procedure's aggregation, complete-process and conformance-scope rules before making a broader decision.
If you are new to this test
For WCAG 3.2.2 On Input, change one material condition at a time where practical. Do not assume that a passing default state covers errors, overlays, orientation changes, interruptions or recovery.
Record this step

Step 4

Apply branches and exceptions

Purpose: For WCAG 3.2.2 On Input, execute the named scenario: Apply branches and exceptions. Target: Each setting change in a user-interface component that can automatically change context. Compare the observation with this result: Every alternative branch or exception used is named and supported by its exact condition.

User impact: Users may lose context, data or control while entering information. This scenario isolates that risk in the action named Apply branches and exceptions.

For WCAG 3.2.2, compare the actual result directly with the normative condition; do not add advisory practice to the pass threshold. Evaluate only these recorded normative exceptions where relevant: Prior advice.

Expected result

Every alternative branch or exception used is named and supported by its exact condition.

Failure observation

After the tester completes the WCAG 3.2.2 On Input scenario named Apply branches and exceptions, the recorded observation for the target is inconsistent with the required result: Every alternative branch or exception used is named and supported by its exact condition.

Setup, evidence and decision guidance
Target
Each setting change in a user-interface component that can automatically change context.
Required state
For WCAG 3.2.2, use the same Warn before context changes caused by input target and state evidence collected in S2.
Tool or command
WCAG 2.2 normative text and Understanding Success Criterion 3.2.2: On Input as informative interpretation.
Record
Selected branch; exception name, condition and evidence; unresolved judgement and resolver.
Pass
Record passed for the WCAG 3.2.2 On Input scenario named Apply branches and exceptions only when the evidence (Selected branch; exception name, condition and evidence; unresolved judgement and resolver.) supports: Every alternative branch or exception used is named and supported by its exact condition.
Fail
Record failed when the action is completed and this failure observation is reproduced: After the tester completes the WCAG 3.2.2 On Input scenario named Apply branches and exceptions, the recorded observation for the target is inconsistent with the required result: Every alternative branch or exception used is named and supported by its exact condition.
Not applicable
The completed scope inventory contains no target matching: Each setting change in a user-interface component that can automatically change context.
Blocked
Record blocked, not passed, when The target is applicable, but a required action, state, environment or evidence item was not completed.
Repeat or recover
Reassess WCAG 3.2.2 when source status, normative wording or the Warn before context changes caused by input target facts change.
Limitations
This WCAG 3.2.2 On Input scenario covers only the action named Apply branches and exceptions for the recorded target and state. It contributes evidence to 3.2.2; apply the procedure's aggregation, complete-process and conformance-scope rules before making a broader decision.

Decide

How to decide

Passed

Changing a setting does not automatically change context unless users were advised before using the component.

Failed

At least one applicable target violates this condition and no documented normative exception applies: Changing a setting does not automatically change context unless users were advised before using the component.

Not applicable
The completed scope inventory contains no target matching: Each setting change in a user-interface component that can automatically change context.
Cannot tell
Whether the resulting change meets the context-change definition or was triggered by input cannot be determined.
Not tested
The target is applicable, but a required action, state, environment or evidence item was not completed.
Aggregation and reporting boundaries

Aggregation: Preserve one result per target and material state. A failed target prevents a passed aggregate; cantTell and untested remain unresolved; inapplicable is used only when no target matches applicability.

WCAG decision: A WCAG 3.2.2 decision is separate from target and ACT outcomes. It requires all applicable content in the declared conformance scope plus WCAG's full-page, complete-process, accessibility-supported-ways and non-interference requirements as applicable.

Automation: A passed automated or ACT check covers only its exact applicability and expectation. Complete all remaining manual, contextual, exception, state and technology checks; never set the criterion to satisfied automatically.

Worked example and outcome calibration

A11Y-WCAG-044-WORKED-001: representative worked example

Context: Representative synthetic example for WCAG 3.2.2 On Input on a fictional, version-frozen product target; no client or participant execution occurred.

Inspected: The tester follows S2 (Warn before context changes caused by input) using the target, required state, tool and repeat rule stated in this procedure.

Observed output: After the tester completes the WCAG 3.2.2 On Input scenario named Warn before context changes caused by input, the recorded observation for the target is inconsistent with the required result: Changing a setting does not automatically change context unless users were advised before using the component.

Evidence:

  • example-evidence-001: target and state record for Each setting change in a user-interface component that can automatically change context.
  • example-evidence-002: contemporaneous observation from the named method — Component/setting, prior advice, action, resulting context and focus/data effect.
  • 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: Changing a setting does not automatically change context unless users were advised before using the component. The failed decision is limited to this synthetic target and state; unexecuted coverage is not inferred.

Decision: failed

Finding: A11Y-WCAG-044-example-finding-001 — Warn before context changes caused by input: expected result is not demonstrated. The represented barrier may affect People who use keyboards, switches, speech input or adapted pointing devices.; Blind people and people using screen readers or braille.; People with cognitive, language, learning or memory disabilities.

Remediation: Change the represented target or process so it demonstrates this result: Changing a setting does not automatically change context unless users were advised before using the component. 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 Warn before context changes caused by input 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
A country selector warns that changing it reloads the form before the control.

The applicable target meets the criterion-specific condition in the stated state.

Failed
Selecting a radio option immediately submits and navigates with no warning.

The applicable target violates the condition and no supported exception applies.

Not applicable
The frozen scope contains no target matching: Each setting change in a user-interface component that can automatically change context.

No target matches applicability; this target outcome is not automatically copied to a WCAG decision.

Cannot tell
Whether the resulting change meets the context-change definition or was triggered by input cannot be determined.

The uncertainty is material and remains unresolved rather than being converted to passed.

Not tested
An applicable warn before context changes caused by input target was inventoried, but a required state or action was not executed.

Applicable coverage remains incomplete.

Sampling, complete processes and platform limitations

Test every in-scope instance when practical. For a large population, document a sample that includes each template, content or control type, meaningful state and high-risk task.

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.

  • 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.
