Why Settings Page Testing Deserves Focus

Settings pages are the control center of any web application. Users reach them to change passwords, adjust notifications, link third‑party accounts, toggle feature flags, or export data. Because they surface privileged actions, a defect here can lead to account lock‑out, data leakage, or unintended service charges. In production, settings‑related bugs often manifest after a user has already invested time in the app, making the impact felt as frustration, support tickets, or churn.

From a testing perspective, the settings area concentrates many risk vectors: form validation, state persistence, cross‑origin requests, role‑based visibility, and accessibility requirements. A single missing server‑side check can allow a malicious user to escalate privileges, while an overlooked focus trap can lock out keyboard‑only users. Because settings pages are frequently updated—new toggles, redesigned layouts, or A/B experiments—regression risk is high. A disciplined test strategy that covers happy paths, error conditions, edge cases, accessibility, and security reduces the chance that a change slips through unnoticed.

Anatomy of a Typical Web Settings Page

Understanding the structural pieces helps you design targeted test cases. Most settings pages share a common layout, though exact implementations vary.

Component	Typical HTML / ARIA Role	Common Interactions	Typical Failure Modes
Header / Breadcrumb	or	View current section, navigate back	Missing heading level, breadcrumb not updated
Navigation Sidebar	with list of links	Switch between sections (Profile, Privacy, Billing)	Links not focusable, ARIA‑current missing
Form Fields	, </code>, custom widgets</td><td>Edit values, pick options, toggle switches</td><td>Incorrect type, missing label, validation not triggered</td></tr> <tr><td>Switch / Toggle</td><td><code><input type="checkbox" role="switch"></code> or custom JS</td><td>Enable/disable feature</td><td>State not persisted, screen reader announces wrong state</td></tr> <tr><td>Save / Apply Button</td><td><code><button type="submit"></code></td><td>Persist changes</td><td>Button disabled incorrectly, double‑submit race</td></tr> <tr><td>Cancel / Reset Link</td><td><code><a></code> or <code><button type="reset"></code></td><td>Discard edits</td><td>Navigation loses unsaved‑data warning</td></tr> <tr><td>Help / Tooltip</td><td><code><span role="tooltip"></code> or <code><div aria-describedby></code></td><td>Show contextual info</td><td>Tooltip not announced, traps focus</td></tr> <tr><td>Validation Messages</td><td><code><div role="alert"></code> or <code><p class="error"></code></td><td>Inline feedback</td><td>Message not live‑region, color‑only indication</td></tr> <tr><td>Export / Import Controls</td><td><code><input type="file"></code>, <code><button></code></td><td>Download/upload data</td><td>File type not restricted, missing CSRF token</td></tr> <tr><td>Account Deactivation</td><td><code><button></code> with confirmation dialog</td><td>Delete account</td><td>Dialog not modal, confirmation not required</td></tr> </table> <p>Each component can be exercised independently, but many defects arise from interactions between them (e.g., changing a toggle while a save request is in flight). Mapping the page to this table gives you a checklist for both manual and automated coverage.</p> <h2>Comprehensive Test Matrix for Settings Pages</h2> <p>Below is a consolidated matrix that you can adapt to your product.

(core happy path) to ensure basic navigation works.</li> <li><strong>Add risk‑based</strong>: If your app handles payments, elevate S24‑S26.</li> <li><strong>Automate where feasible</strong>: Most validation and API interaction tests (S3, S4, S9‑S12, S23‑S25) are ideal for UI‑driven automation.</li> <li><strong>Manual exploratory</strong>: Cases involving timing (S16‑S17), dialogs (S6, S26), or cross‑browser rendering (S29‑S30) benefit from human observation combined with tooling.</li> </ul> <h2>Manual Testing Approach: Step‑by‑Step</h2> <p>Even with strong automation, a disciplined manual pass catches nuances that scripts may miss, especially around user perception and intermittent timing. Follow this procedure for each settings release.</p> <ol> <li><strong>Environment Preparation</strong></li> </ol> <ul> <li>Use a clean profile or incognito window to avoid cached state.</li> <li>Log in with a test account that has the full set of permissions you intend to verify (admin, standard, restricted).</li> <li>Disable extensions that could alter DOM (e.g., ad blockers) unless they are part of your threat model.</li> </ul> <ol> <li><strong>Initial Load & Navigation</strong></li> </ol> <ul> <li>Open the settings page via the main menu. Verify URL changes and that the page title updates.</li> <li>Confirm that the heading level matches the site’s hierarchy (usually <code><h1></code>).</li> <li>Use the keyboard (<code>Tab</code>) to move focus from the browser address bar to the first focusable element; ensure a visible focus ring appears.</li> </ul> <ol> <li><strong>Section Switching</strong></li> </ol> <ul> <li>Click each sidebar link. Observe that the URL updates with a predictable pattern (e.g., <code>/settings#profile</code>).</li> <li>After each click, press <code>Shift+Tab</code> to return focus to the sidebar and verify that the newly selected item receives <code>aria-current="page"</code> or an equivalent visual highlight.</li> <li>Resize the viewport to trigger the responsive breakpoint; confirm the sidebar converts to a bottom navigation bar and that touch targets are ≥ 48 dp.</li> </ul> <ol> <li><strong>Form Field Interaction</strong></li> </ol> <ul> <li>For each editable field:</li> </ul> <p>a. Clear the field, type a valid value, and note any live character counter.</p> <p>b. Press <code>Enter</code> or click the Save button; watch for a spinner or disabled state.</p> <p>c. After the response, verify the field retains the entered value and that a toast or inline confirmation appears.</p> <p>d. Repeat with an invalid value (e.g., letters in a number field) and confirm that the error message appears, the field receives <code>aria-invalid="true"</code>, and focus remains on the field.</p> <ol> <li><strong>Toggle / Switch Behavior</strong></li> </ol> <ul> <li>Activate a switch, then immediately deactivate it before any network response returns. The UI should show a pending state (spinner) and not flip back until the request settles.</li> <li>Disconnect the network (Chrome DevTools → Offline) and toggle; the switch should either revert locally with a warning or stay unchanged until connectivity resumes.</li> </ul> <ol> <li><strong>Save / Cancel Flow</strong></li> </ol> <ul> <li>Edit multiple fields across different sections, then click Save. Confirm that a single consolidated request is sent (check Network tab) containing all changed values.</li> <li>Click Cancel before saving; a modal should ask “Discard changes?”. Confirming discards restores original values; declining keeps edits.</li> </ul> <ol> <li><strong>Export / Import</strong></li> </ol> <ul> <li>Trigger export; verify the file downloads with the expected name and mime type. Open the file in a text editor to confirm JSON/CSV structure and that no extra metadata (like internal IDs) is leaked.</li> <li>For import, first upload a valid file; ensure settings update accordingly. Then upload a file with a malformed section; the UI should show an inline error and leave existing settings untouched.</li> </ul> <ol> <li><strong>Accessibility Spot‑Check</strong></li> </ol> <ul> <li>Run a screen reader (NVDA, VoiceOver, or TalkBack via browser) and navigate the page. Listen for announcements of labels, states, and errors.</li> <li>Use the axe extension or manually inspect color contrast with a tool like WebAIM Contrast Checker.</li> <li>Verify that modal dialogs trap focus and return it to the triggering element upon close.</li> </ul> <ol> <li><strong>Security & Privacy Checks</strong></li> </ol> <ul> <li>Attempt to change password without providing the current one; ensure the server returns a validation blocks the request.</li> <li>Inspect network calls for any session tokens appearing in query strings or request payloads that could be logged.</li> <li>Trigger the account deletion flow; verify that a re‑authentication prompt appears and that the final request includes a CSRF token.</li> </ul> <ol> <li><strong>Post‑Test Cleanup</strong></li> </ol> <ul> <li>Log out, clear cookies, and repeat the steps with a different role (e.g., a user with limited permissions) to confirm that UI elements are correctly hidden or disabled.</li> <li>Document any inconsistencies in a shared test‑rail or spreadsheet, linking each defect to the matrix ID for traceability.</li> </ul> <p>By following this checklist, you create a repeatable baseline that can be executed before each release candidate build.</p> <h2>Automated Testing Approaches and Tooling</h2> <p>Automation excels at repetitive validation, API contract checks, and regression guarding. For web settings pages, the most common stacks are:</p> <table> <tr><th>Tool</th><th>Language</th><th>Strengths for Settings Testing</th><th>Typical Setup</th></tr> <tr><td>Playwright</td><td>JavaScript/TypeScript, Python, .NET</td><td>Auto‑wait, built‑in tracing, supports multiple browsers, handles dialogs natively</td><td><code>npm i -D @playwright/test</code></td></tr> <tr><td>Cypress</td><td>JavaScript</td><td>Fast test runner, time‑travel debugging, easy custom commands</td><td><code>npm i -D cypress</code></td></tr> <tr><td>Selenium WebDriver</td><td>Java, C#, Python, JS</td><td>Grid support, language flexibility, mature ecosystem</td><td><code>pip install selenium</code></td></tr> <tr><td>TestCafe</td><td>JavaScript/TypeScript</td><td>No WebDriver needed, automatic waiting, built‑in reporting</td><td><code>npm i -D testcafe</code></td></tr> <tr><td>Axios + Jest (API‑only)</td><td>JavaScript</td><td>Pure contract testing, quick feedback</td><td><code>npm i -D axios jest</code></td></tr> </table> <p>Below is a concise comparison to help you pick a stack based on team expertise and infrastructure.</p> <table> <tr><th>Criteria</th><th>Playwright</th><th>Cypress</th><th>Selenium</th><th>TestCafe</th><th>API‑Only</th></tr> <tr><td>Cross‑browser (Chrome/Firefox/Safari/Edge)</td><td>✅</td><td>✅ (limited Safari)</td><td>✅</td><td>✅</td><td>N/A</td></tr> <tr><td>Auto‑wait for network/idle</td><td>✅</td><td>✅ (via <code>cy.wait</code>)</td><td>❌ (explicit waits)</td><td>✅</td><td>N/A</td></tr> <tr><td>Built‑in tracing/video</td><td>✅</td><td>❌ (plugins)</td><td>❌</td><td>✅</td><td>N/A</td></tr> <tr><td>Handling of dialogs/alerts</td><td>✅ (auto‑accept/dismiss)</td><td>✅</td><td>❌ (requires switchTo)</td><td>✅</td><td>N/A</td></tr> <tr><td>Parallel sharding</td><td>✅</td><td>✅ (via cypress‑parallel)</td><td>✅ (Selenium Grid)</td><td>✅</td><td>N/A</td></tr> <tr><td>Language flexibility</td><td>✅ (JS/TS/Python/.NET)</td><td>❌ (JS/TS only)</td><td>✅</td><td>❌ (JS/TS only)</td><td>✅ (any)</td></tr> <tr><td>Learning curve</td><td>Moderate</td><td>Low</td><td>High</td><td>Low</td><td>Low (if API known)</td></tr> <tr><td>CI integration</td><td>Excellent</td><td>Excellent</td><td>Good</td><td>Good</td><td>Excellent</td></tr> </table> <p><strong>Choosing a tool</strong></p> <ul> <li>If you need pixel‑perfect visual regression across browsers, Playwright’s tracing and video capture are advantageous.</li> <li>For teams already writing end‑to‑end tests in JavaScript and valuing fast feedback, Cypress offers a low‑friction entry point.</li> <li>When you must test against a Selenium Grid already in place for other suites, sticking with Selenium avoids duplication.</li> <li>API‑only tests are perfect for validating that the settings endpoint correctly processes payloads, but they do not catch UI‑specific bugs like missing labels or focus traps.</li> </ul> <h2>Concrete Automation Examples</h2> <p>Below are ready‑to‑copy snippets for the three most common scenarios: verifying a text field update, asserting a toggle persists after reload, and checking that an error message appears for invalid input. Each example uses Playwright (JS) because it illustrates auto‑wait and tracing, but equivalent Cypress or Selenium code follows the same logic.</p> <h3>1. Text Field Update</h3> <pre><code> // settings.test.js const { test, expect } = require('@playwright/test'); test('updates display name and persists after reload', async ({ page }) => { // 1. Log in (reuse a helper or fixture) await page.goto('https://app.example.com/login'); await page.fill('#email', 'qa@example.com'); await page.fill('#password', 'SecurePass!123'); await page.click('button[type="submit"]'); await page.waitForURL('https://app.example.com/dashboard'); // 2. Navigate to settings await page.click('nav >> text=Settings'); await page.waitForURL('/settings'); // 3. Locate the display name field (assume label associated) const nameInput = page.getByLabel('Display name'); await expect(nameInput).toHaveValue('Old Name'); // sanity check // 4. Edit and save await nameInput.fill('New Name 🚀'); await page.click('button:has-text("Save")'); // 5. Wait for success toast and verify API call await expect(page.getByText('Settings saved')).toBeVisible({ timeout: 5000 }); const [response] = await Promise.all([ page.waitForResponse(resp => resp.url().endsWith('/api/user') && resp.request().method() === 'PATCH'), page.waitForLoadState('networkidle') ]); const json = await response.json(); expect(json.displayName).toBe('New Name 🚀'); // 6. Reload and confirm persistence await page.reload(); await expect(nameInput).toHaveValue('New Name 🚀'); }); </code></pre> <p><strong>What this covers</strong></p> <ul> <li>Authentication flow (reuseable fixture).</li> <li>Navigation and URL assertions.</li> <li>Label‑based locator (accessibility‑friendly).</li> <li>Autosave spinner handling via <code>waitForLoadState('networkidle')</code>.</li> <li>Network request validation to ensure the correct PATCH payload.</li> <li>Persistence check after a hard reload.</li> </ul> <h3>2. Toggle Persistence</h3> <pre><code> test('toggle notification setting survives page reload', async ({ page }) => { await loginViaUI(page); // assume helper defined elsewhere await page.goto('https://app.example.com/settings/notifications'); const toggle = page.getByLabel('Email notifications'); // Ensure initial state is off await expect(toggle).toHaveAttribute('aria-checked', 'false'); // Turn on await toggle.click(); await expect(toggle).toHaveAttribute('aria-checked', 'true'); await expect(page.getByText('Saving…')).toBeHidden(); // spinner disappears // Reload await page.reload(); await expect(toggle).toHaveAttribute('aria-checked', 'true'); }); </code></pre> <p><strong>Key points</strong></p> <ul> <li>Uses <code>aria-checked</code> to verify the accessible state, not just visual CSS.</li> <li>Checks for a transient saving indicator to avoid race conditions.</li> </ul> <h3>3. Invalid Input Error</h3> <pre><code> test('shows inline error for malformed email', async ({ page }) => { await loginViaUI(page); await page.goto('https://app.example.com/settings/profile'); const emailInput = page.getByLabel('Email address'); await emailInput.fill('not-an-email'); await page.click('button:has-text("Save")'); // Error message should be a live region const error = page.getByRole('alert'); await expect(error).toContainText('Enter a valid email address'); await expect(emailInput).toHaveAttribute('aria-invalid', 'true'); // Ensure form did not submit await expect(page).notToHaveURL('/api/user'); }); </code></pre> <p><strong>Why this works</strong></p> <ul> <li>Asserts both visual message and ARIA state.</li> <li>Confirms that the request never leaves the client (important for preventing bad data).</li> </ul> <p><strong>Running the suite</strong></p> <pre><code> # Install dependencies npm ci # Run headed mode for debugging npx playwright test --headed # Run in CI with tracing npx playwright test --output=test-results --trace=on </code></pre> <p>The trace viewer (<code>npx playwright show-trace</code>) lets you inspect DOM snapshots at each action, invaluable for debugging intermittent UI glitches.</p> <h2>Autonomous Persona‑Driven Exploration: Where Scripts Miss Bugs</h2> <p>Even a well‑crafted automated suite can overlook issues that appear only under specific user behaviors, device contexts, or unexpected interaction sequences. Autonomous testing platforms like <strong>SUSA</strong> address this gap by exploring the application without pre‑written scripts, using simulated user personas that embody distinct goals and interaction styles.</p> <h3>How Persona‑Driven Exploration Works</h3> <p>SUSA builds a state graph of the application as it interacts. Each node represents a unique screen or modal; edges correspond to actions such as taps, clicks, scrolls, or form submissions. The engine starts from a known entry point (e.g., the landing page) and then:</p> <ol> <li><strong>Selects a persona</strong> – each persona has a probability distribution over actions (e.g., a curious persona clicks every visible link; an impatient persona double‑clicks buttons; an elderly persona prefers larger touch targets and avoids rapid gestures).</li> <li><strong>Executes an action</strong> – the platform performs the chosen interaction, waits for network idle, and records the resulting state.</li> <li><strong>Updates the graph</strong> – if the state is new, it’s added; if it’s a known state, the edge weight is increased.</li> <li><strong>Detects anomalies</strong> – JavaScript errors, uncaught promises, excessive DOM mutations, or accessibility violations trigger immediate flags.</li> <li><strong>Learns from dead ends</strong> – actions that consistently leading to a broken link or infinite loading spinner are marked as low‑probability for future runs, allowing the engine to focus on unexplored but promising paths.</li> </ol> <p>Because the exploration is guided by behavior models rather than static test cases, it can surface problems such as:</p> <ul> <li>A <strong>power‑user</strong> who rapidly toggles a switch ten times in succession exposing a race condition that leaves the backend flag stuck.</li> <li>An <strong>adversarial</strong> persona that submits extremely long strings ( > 10 KB ) into a nickname field, revealing a missing server‑side length check that later causes UI truncation.</li> <li>An <strong>elderly</strong> persona who relies on zoom (200 %) and discovers that a modal’s fixed‑pixel width causes horizontal scrolling, breaking the WCAG 1.4.4 resize text criterion.</li> <li>A <strong>novice</strong> persona who attempts to navigate via the browser’s back button after a partial save, finding that the back navigation restores a stale state because the page did not push a new history entry.</li> </ul> <p>These scenarios are rarely captured by scripted tests because they depend on timing, gesture patterns, or contextual decisions that a script would not think to try unless explicitly programmed.</p> <h3>Integrating SUSA into a CI Pipeline</h3> <p>You can run SUSA as a lightweight container alongside your unit and integration tests. A typical command looks like:</p> <pre><code> # Pull the latest agent image docker pull susatest/agent:latest # Run exploration against a staging build (replace with your URL) docker run --rm \ -e SUSA_TARGET_URL=https://staging.example.com \ -e SUSA_PERSONAS=curious,impatient,elderly,adversarial \ -e SUSA_OUTPUT_DIR=/app/reports \ -v $(pwd)/reports:/app/reports \ susatest/agent:latest </code></pre> <p>The agent will:</p> <ul> <li>Crawl the settings section (and any linked pages) for a configurable time budget (e.g., 15 minutes).</li> <li>Produce a JSON report detailing discovered states, encountered errors, and any WCAG violations.</li> <li>Optionally generate regression scripts (Playwright for Android WebView, Playwright for Web) that you can add to your automated suite.</li> </ul> <h3>What to Do With the Findings</h3> <ol> <li><strong>Triangulate</strong> – Match each SUSA finding to a matrix ID (e.g., S14 for long strings, S16 for rapid toggle). If a finding maps to an existing ID, prioritize fixing the root cause; if it creates a new ID, add it to your matrix.</li> <li><strong>Convert to Regression</strong> – Use the auto‑generated Playwright script as a starting point, then refine assertions to match your team’s conventions.</li> <li><strong>Feed Persona Data</strong> – Adjust your manual exploratory charters to include the specific behavior patterns that triggered the bug (e.g., “test rapid double‑click on save under slow 3G”).</li> <li><strong>Monitor Production</strong> – Instrument the same error detectors (JS exception capture, long task monitoring) used by SUSA in your real‑user monitoring (RUM) tool to confirm that the issue does not resurface in live traffic.</li> </ol> <p>By blending scripted verification with autonomous persona exploration, you gain confidence that both the expected flows and the unexpected, real‑world usage patterns are under control.</p> <h2>Production‑Only Gotchas and Monitoring</h2> <p>Some defects only manifest when the application runs at scale, under varying network conditions, or with real user data that differs from your test fixtures. Anticipating these helps you instrument proper observability.</p> <h3>Common Production‑Only Settings Issues</h3> <table> <tr><th>Symptom</th><th>Typical Cause</th><th>Detection Strategy</th></tr> <tr><td>Settings appear to save but revert after a few minutes</td><td>Backend eventually validates and rejects the payload (e.g., duplicate unique constraint) but UI does not show error</td><td>End‑to‑end synthetic transaction that reads the setting after a delay; alert on mismatch</td></tr> <tr><td>Intermittent “Save” button stays disabled</td><td>Race condition where a pending request leaves the button in disabled state because the failure handler never re‑enables it</td><td>Monitor click‑to‑enabled time via RUM; flag if > 2 s on > 1 % of sessions</td></tr> <tr><td>Users report missing accessibility labels after a UI redesign</td><td>New component library version omitted <code>aria-label</code> on custom switches</td><td>Run automated axe CI job on each deploy; also sample a small percentage of real sessions with a browser extension that logs missing labels</td></tr> <tr><td>Export file contains raw internal IDs despite consent settings</td><td>Permission check bypassed during file generation step</td><td>Add a checksum or hash of exported fields to a metrics dashboard; alert when unexpected fields appear</td></tr> <tr><td>Settings page loads slowly on low‑end devices</td><td>Heavy JavaScript bundle loads unnecessary modules for settings (e.g., editor library)</td><td>Use Web Vitals (LCP, FID) segmented by device class; set performance budgets</td></tr> <tr><td>CSP violation reports in console after a third‑party widget integration</td><td>Widget injects inline script not covered by policy</td><td>Enable CSP report‑only mode in prod, forward reports to a SIEM; block on first violation</td></tr> <tr><td>Two‑factor authentication toggle disappears for users with legacy auth method</td><td>Feature flag mis‑aligned with user‑segment data</td><td>Log flag evaluation outcomes; create an alert when mismatch > 0.5 % of active sessions</td></tr> </table> <h3>Instrumentation Tips</h3> <ol> <li><strong>Synthetic Transactions</strong> – Deploy a lightweight Playwright script that logs in, navigates to settings, toggles a flag, logs out, and then re‑logs in after 5 minutes to read the persisted value. Schedule it every 5 minutes in a staging‑like environment and also in a canary prod slot.</li> </ol> <ol> <li><strong>Custom Metrics</strong> – Instrument the frontend with <code>window.__SETTINGS_METRICS__ = { saveLatency: ..., toggleCount: ... }</code> and push these to your monitoring backend (e.g., Prometheus, Datadog). Set alerts on sudden spikes or deviations from baseline.</li> </ol> <ol> <li><strong>Error Boundaries</strong> – Wrap the settings React/Vue component tree in an error boundary that captures unhandled exceptions and sends them to your error‑tracking service (Sentry, Rollbar). Include the current URL and user persona data (if you have feature flags for persona targeting).</li> </ol> <ol> <li><strong>Accessibility Audits in Production</strong> – Use the <code>axe-core</code> library in a low‑overhead mode that runs on a small sample of page views (e.g., 1 % of sessions). Aggregate violations and notify the frontend team when new issues appear.</li> </ol> <ol> <li><strong>Feature Flag Telemetry</strong> – Whenever a settings toggle changes a flag, log the old and new values together with the user ID, timestamp, and any experiment IDs. This enables you to detect when a flag fails to persist or is overwritten by another service.</li> </ol> <p>By combining these observability techniques with your pre‑release test matrix, you close the loop between what you verify in a controlled environment and what actually happens in the wild.</p> <h2>Settings Page Testing Checklist (Ready‑to‑Print)</h2> <table> <tr><th>✅ Item</th><th>Description</th><th>Frequency</th></tr> <tr><td><strong>Navigation</strong></td><td>Settings reachable via main menu, URL updates, breadcrumb reflects current section</td><td>Each release</td></tr> <tr><td><strong>Section Load</strong></td><td>Every sidebar section loads without console errors, heading present</td><td>Each release</td></tr> <tr><td><strong>Field Labels</strong></td><td>All inputs have associated <code><label></code> or <code>aria-label</code>; screen reader announces purpose</td><td>Each release</td></tr> <tr><td><strong>Valid Edits</strong></td><td>Text, number, date, and selector fields accept valid values and persist after reload</td><td>Each release</td></tr> <tr><td><strong>Invalid Input</strong></td><td>Inline validation appears, field receives <code>aria-invalid</code>, form does not submit</td><td>Each release</td></tr> <tr><td><strong>Toggle State</strong></td><td>Switches reflect <code>aria-checked</code> state, visual change matches, value saved to backend</td><td>Each release</td></tr> <tr><td><strong>Save Button</strong></td><td>Disabled during request, shows spinner, re‑enables on success/error; prevents double submit</td><td>Each release</td></tr> <tr><td><strong>Cancel / Discard</strong></td><td>Modal appears, discarding changes restores original values; confirming keeps edits</td><td>Each release</td></tr> <tr><td><strong>Export</strong></td><td>File downloads with correct mime/type, content matches current settings, no extra metadata</td><td>Each release</td></tr> <tr><td><strong>Import</strong></td><td>Valid file updates settings; malformed file shows error and leaves settings unchanged</td><td>Each release</td></tr> <tr><td><strong>Keyboard Flow</strong></td><td>Tab order matches visual order, visible focus indicator, no trapped focus</td><td>Each release</td></tr> <tr><td><strong>Contrast</strong></td><td>Text and icons meet WCAG AA (4.5:1 normal, 3:1 large)</td><td>Each release</td></tr> <tr><td><strong>Screen Reader</strong></td><td>Labels, states, and errors announced correctly; live regions used for messages</td><td>Each release</td></tr> <tr><td><strong>Password Change</strong></td><td>Requires current password, enforces policy, does not leak token in URL or logs</td><td>Each release</td></tr> <tr><td><strong>Account Deletion</strong></td><td>Requires re‑authentication, confirmation dialog, CSRF token protected</td><td>Each release</td></tr> <tr><td><strong>Network Resilience</strong></td><td>Offline toggle shows warning, changes queued and retried on connection</td><td>Each release</td></tr> <tr><td><strong>Performance</strong></td><td>LCP < 2.5 s, FID < 100 ms on mid‑tier device under 3G simulation</td><td>Each release</td></tr> <tr><td><strong>CSP</strong></td><td>No inline script/style violations; report‑only mode logs none</td><td>Each release</td></tr> <tr><td><strong>Feature Flag Guard</strong></td><td>Toggles only visible when corresponding flag is enabled for the user</td><td>Each release</td></tr> <tr><td><strong>Persona Sanity</strong></td><td>Run a short SUSA exploration (5 min) targeting curious, impatient, elderly personas; no new critical alerts</td><td>Weekly or per‑major‑release</td></tr> <tr><td><strong>Regression Script</strong></td><td>Auto‑generated Playwright script from latest SUSA run committed to repo</td><td>After each SUSA run</td></tr> <tr><td><strong>Monitoring Alerts</strong></td><td>Synthetic transaction success rate > 99 %; error‑boundary rate < 0.1 %</td><td>Ongoing</td></tr> </table> <p>Mark each item as completed before promoting a build to production.
