Explanation of Change

Removed @typescript-eslint/no-unsafe-type-assertion violations from 15 unit-test files as part of Expensify/App issue #94739.

What changed:

  • Replaced unsafe assertions in fixtures, mocked hooks, Octokit methods, Onyx data, matcher inputs, and invalid-input tests with production-derived types, repository-native typed mocks, direct narrowing, and narrowly documented invalid-input boundaries.
  • Preserved complete production signatures and response types in the deploy-checklist mocks, including optional request parameters and explicit failures for unexpected missing parameters.
  • Preserved existing scenarios, fixture values, call selection, expectations, and runtime behavior. No production source, UI, styling, assets, copy, navigation behavior, or user-facing behavior changed.
  • Restored the complete policy-change-log handler orphan check and removed generic test-local Octokit helpers after independent review identified those required corrections.

Why this approach is safe:

  • Every target cleanup count is zero; focused formatting, lint, Jest, changed-path enforcement, restoration, and diff checks passed.
  • The verifier reported no authorized-path type diagnostic. Its local focused typecheck had partial coverage only because of an unrelated AddressSearch diagnostic outside this PR.
  • Fresh independent scope, type-safety, and regression reviews are clean for the final exact diff.
  • Exact-head Fork CI passed typecheck, lint, format, React Compiler, and all 15 targeted Jest suites on signed commit b1a113c87e6888a1fdc3cb2eaafb9c78aca1f45e in provider run 30588995129.
  • Manual platform, high-traffic-account, offline, visual, Storybook, deeplink, message-formatting, design, CSS, asset, and copy testing are not applicable because this PR changes test implementation only.

Fixed Issues

$ #94739
PROPOSAL: #94739 (comment)

Tests

  1. Run focused lint for the 15 changed files and verify there are no target-rule warnings.
  2. Run the focused Jest suites for all 15 changed test files and verify they pass.
  3. Run git diff --check and verify the tracked Seatbelt TSV remains byte-identical.
  4. Verify exact-head Fork CI provider run 30588995129 passes typecheck, lint, format, React Compiler, and Jest for commit b1a113c87e6888a1fdc3cb2eaafb9c78aca1f45e.

Failure-scenario coverage is supplied by the existing focused Jest scenarios. Browser/device console checks and manual platform execution are not applicable to this test-only change.

Offline tests

Not applicable because this is a test-only type-safety cleanup with no production network, storage, or offline behavior changes.

QA Steps

Not applicable for staging or production QA because production behavior and user-interface code are unchanged. Validation is fully automated by focused verification, independent review, and exact-head Fork CI.

PR Author Checklist

  • I linked the correct issue in the ### Fixed Issues section above
  • I wrote clear testing steps that cover the changes made in this PR
    • I added steps for local testing in the Tests section
    • I added steps for the expected offline behavior in the Offline steps section
    • I added steps for Staging and/or Production testing in the QA steps section
    • I added steps to cover failure scenarios (i.e. verify an input displays the correct error message if the entered data is not correct)
    • I turned off my network connection and tested it while offline to ensure it matches the expected behavior (i.e. verify the default avatar icon is displayed if app is offline)
    • I tested this PR with a High Traffic account against the staging or production API to ensure there are no regressions (e.g. long loading states that impact usability).
  • I included screenshots or videos for tests on all platforms
  • I ran the tests on all platforms & verified they passed on:
    • Android: Native
    • Android: mWeb Chrome
    • iOS: Native
    • iOS: mWeb Safari
    • MacOS: Chrome / Safari
  • I verified there are no console errors (if there's a console error not related to the PR, report it or open an issue for it to be fixed)
  • I followed proper code patterns (see Reviewing the code)
    • I verified that comments were added to code that is not self explanatory
    • I verified that any new or modified comments were clear, correct English, and explained "why" the code was doing something instead of only explaining "what" the code was doing.
    • I verified any copy / text that was added to the app is grammatically correct in English. It adheres to proper capitalization guidelines (note: only the first word of header/labels should be capitalized), and is either coming verbatim from figma or has been approved by marketing (in order to get marketing approval, ask the Bug Zero team member to add the Waiting for copy label to the issue)
  • If a new code pattern is added I verified it was agreed to be used by multiple Expensify engineers
  • I followed the guidelines as stated in the Review Guidelines
  • I tested other components that can be impacted by my changes (i.e. if the PR modifies a shared library or component like Avatar, I verified the components using Avatar are working as expected)
  • If a new CSS style is added I verified that:
    • A similar style doesn't already exist
    • The style can't be created with an existing StyleUtils function (i.e. StyleUtils.getBackgroundAndBorderStyle(theme.componentBG))
  • If new assets were added or existing ones were modified, I verified that:
    • The assets are optimized and compressed (for SVG files, run npm run compress-svg)
    • The assets load correctly across all supported platforms.
  • If the PR modifies code that runs when editing or sending messages, I tested and verified there is no unexpected behavior for all supported markdown - URLs, single line code, code blocks, quotes, headings, bold, strikethrough, and italic.
  • If the PR modifies a generic component, I tested and verified that those changes do not break usages of that component in the rest of the App (i.e. if a shared library or component like Avatar is modified, I verified that Avatar is working as expected in all cases)
  • If the PR modifies a component related to any of the existing Storybook stories, I tested and verified all stories for that component are still working as expected.
  • If the PR modifies a component or page that can be accessed by a direct deeplink, I verified that the code functions as expected when the deeplink is used - from a logged in and logged out account.
  • If the PR modifies the UI (e.g. new buttons, new UI components, changing the padding/spacing/sizing, moving components, etc) or modifies the form input styles:
    • I verified that all the inputs inside a form are aligned with each other.
    • I added Design label and/or tagged @Expensify/design so the design team can review the changes.
  • I added unit tests for any new feature or bug fix in this PR to help automatically prevent regressions in this user flow.
  • If the main branch was merged into this PR after a review, I tested again and verified the outcome was still expected according to the Test steps.

Count change

Current baseline source:

  • config/eslint/eslint.seatbelt.tsv at pinned base 1abb329427c79458aeca2e8e5f66d6fe6e5f1262.

Before:

  • tests/unit/FailureNotifierTest.ts: 4 violations
  • tests/unit/HrUtilsTest.ts: 4 violations
  • tests/unit/OnyxUpdateManagerTest.ts: 4 violations
  • tests/unit/PolicyChangeLogContentTest.tsx: 4 violations
  • tests/unit/PopoverMenuV2Test.tsx: 4 violations
  • tests/unit/ReceiptAlternativeMethodsTest.tsx: 4 violations

  • tests/unit/hooks/useRestoreWorkspacesTabOnNavigate.test.ts: 4 violations
  • tests/unit/hooks/useSplitParticipants.test.tsx: 4 violations
  • tests/unit/isDeployChecklistLockedTest.ts: 4 violations
  • tests/unit/libs/PersonalDetailsUtilsTest.ts: 4 violations
  • Total: 60 violations

After:

  • Every one of the 15 target files: 0 violations.

Net reduction:

  • 60 fewer @typescript-eslint/no-unsafe-type-assertion violations across 15 files.

TSV evidence:

  • Authoritative verification removed the target rows while counting and restored config/eslint/eslint.seatbelt.tsv byte-for-byte afterward.
  • The generated TSV is intentionally absent from this PR because Expensify/App post-merge automation tightens the baseline on main.

Screenshots/Videos

Not applicable on Android Native, Android mWeb Chrome, iOS Native, iOS mWeb Safari, or MacOS Chrome/Safari because this PR changes only test implementation and has no visual output.

🟡 tests/unit/HrUtilsTest.ts:122 stubTranslate: Dead conditional, both branches return path

This is the same no-op parameters-gate that showed up in #97479 (FileUtils/useAutoCreateSubmitWorkspace). It reads like an unfinished interpolation and a future reader can't tell if it's intentional.

Rest params don't trip unused-var lint, so just const stubTranslate: LocaleContextProps['translate'] = (path) => path;.

Worth stamping out consistently across the series before it keeps propagating ❌

🟡 DRY: tests/unit/createOrUpdateDeployChecklistTest.ts: The mockListIssues.mockImplementation((...parameters) => { ...guard... ; url-or-direct label extraction ; ... }) block is copy-pasted ~10 times (~18 lines each, ~180 lines total).

Every copy is byte-identical except the returned data. Extract one helper and pass just the label → response map:

function mockListIssuesByLabel(responseByLabel: Partial<Record<string, OctokitIssueItem[]>>) {
    mockListIssues.mockImplementation((...parameters: ListForRepoParameters): Promise<ListForRepoResponse> => {
        const received = parameters[0];
        if (!received) throw new Error('GithubUtils issues.listForRepo mock requires request parameters.');
        let labels: string | undefined;
        if ('url' in received) {
            if (typeof received.url !== 'string') throw new Error('listForRepo request options require a string URL.');
            labels = new URL(received.url).searchParams.get('labels') ?? undefined;
        } else {
            labels = received.labels;
        }
        return Promise.resolve(createMock<ListForRepoResponse>({data: (labels && responseByLabel[labels]) ?? [], headers: {}}));
    });
}

Why it matters: this is the file most likely to be touched again (octokit/paginate is fiddly), and 10 identical url-parsing blocks means 10 places to fix when the shape shifts. The dedup also makes each test read as "STAGING_DEPLOY returns these issues" instead of 18 lines of plumbing.

🟢 LGTM - Only two 🟡 non-blocking comments ☝️

Solid cleanup, same series as #97285 / #97317 / #97479, but this one carries more genuine logic change than its siblings (the deploy-checklist octokit rewrite, the PolicyChangeLog orphan-check restructure, dozens of Card/CardsList fixtures gaining now-required fields). All of it is production-derived typing done carefully, and the author flagged the two riskiest edits in the description ✅
