Test Coverage Analysis: PR #2807 — NHR Document List Pagination

Summary

Overall, the test coverage for this PR is solid. The unit helpers are thoroughly tested, the component-level pagination behaviors are well exercised, and the approach follows project conventions (Vitest, React Testing Library, behavioral assertions). There are no critical gaps that represent regression risks, but there are several meaningful behavioral scenarios that are untested — one of which deserves attention before merge.

Critical Gaps

1. handleApplyFilters does not reset page in controlled mode (Rating: 8)

In NhrDocumentList.tsx lines 48–51, handleApplyFilters calls setCurrentPage(1) before delegating to either onApplyFilters or the internal setter. The existing test 'resets to first page when data changes after filtering' (line 231) tests the page reset by changing the data prop via rerender — it does not actually trigger handleApplyFilters. It simulates what happens after an external filter call updates data, which is a different code path.

The code path that matters is: user is on page 2, clicks "Apply Filters" in the panel → handleApplyFilters fires → setCurrentPage(1) is called. No test exercises this sequence. If someone removed the setCurrentPage(1) call from handleApplyFilters, the existing tests would not catch it.

The test at line 231 also never verifies the currentPage prop received by the mock table equals 1 after the filter application — it only checks row content changes from the rerender. This means the "reset to page 1" guarantee from handleApplyFilters is untested.

A test to add:

it('resets to first page when filters are applied while on page 2', async () => {
  const user = userEvent.setup()

  render(
    <NhrDocumentList
      columns={mockColumns}
      filters={mockFilters}
      patient={mockPatient}
      data={createMockDocuments(25)}
      isLoading={false}
    />
  )

  await user.click(screen.getByRole('button', { name: '2' }))
  expect(screen.getByText('Page: 2')).toBeInTheDocument()

  await user.click(screen.getByText(/Filters \(0\)/))
  await user.click(screen.getByText('Apply Filters'))

  expect(screen.getByText('Page: 1')).toBeInTheDocument()
})

Important Improvements

2. NhrDocumentListTable — pagination props are not meaningfully asserted (Rating: 6)

The table test file (NhrDocumentListTable.test.tsx) verifies that a <nav> pagination element is rendered (line 56–59), but never asserts: - That the currentPage prop is passed down to the Pagination component - That nbRowsPerPage is set to PAGE_SIZE (20) - That onPageChange callback fires when a page is clicked - That total is wired correctly to the Pagination component

Since NhrDocumentListTable is a thin wrapper that glues Pagination props to PAGE_SIZE, the meaningful behavior contract is that these props are forwarded correctly. If someone changed nbRowsPerPage={PAGE_SIZE} to nbRowsPerPage={10}, no test would fail. Given that the Pagination component from the design system controls page count calculation, incorrect nbRowsPerPage would produce wrong page numbers.

A targeted test:

it('should render pagination with correct page count for given total', () => {
  setup(
    <NhrDocumentListTable
      columns={mockColumns}
      isLoading={false}
      rows={[]}
      currentPage={1}
      total={45}
      onPageChange={() => {}}
    />
  )

  // With PAGE_SIZE=20 and total=45, there should be 3 pages
  expect(screen.getByRole('button', { name: '3' })).toBeInTheDocument()
  expect(screen.queryByRole('button', { name: '4' })).not.toBeInTheDocument()
})

3. resultCountProp override behavior is untested (Rating: 5)

NhrDocumentList.tsx line 54: const resultCount = resultCountProp ?? data?.length. The tests cover data?.length as source (line 299) and undefined data (line 306), but never test the case where resultCountProp is explicitly provided and overrides data.length. This is the server-side pagination path described in the JSDoc comment. If the ?? were accidentally changed to &&, the override behavior would silently break.

Test Quality Issues

4. 'resets to first page when data changes after filtering' tests the wrong mechanism

As noted above, this test (line 231) uses rerender with new data props to simulate what happens after filtering. What it actually verifies is that when data shrinks (from 25 to 5 items), documents from the now-empty page 2 are no longer visible. This is a consequence of getPagedData returning an empty slice, not of setCurrentPage(1) being called.

The mock table renders rows by content, so even if currentPage were still 2, getPagedData(createMockDocuments(5), 2) returns [], making Document 1-5 invisible. The test would pass even if setCurrentPage(1) were removed from handleApplyFilters. This is a false positive — it gives confidence in page-reset behavior that the test does not actually exercise.

The fix is to also assert on the currentPage value displayed by the mock table (Page: 1), which would confirm setCurrentPage(1) was called.

5. PAGE_SIZE test is implementation-pinning (Rating: low concern)

The test 'should be 20' (line 6–8) locks the value of PAGE_SIZE to 20. While this is generally fine for a business constant, it means any intentional change to the page size requires updating this test. This is a minor issue but worth noting — the more meaningful test is that getPagedData slices correctly relative to PAGE_SIZE, which is already tested generically.

Positive Observations

• nhrPaginationHelpers.test.ts is exemplary. It covers all meaningful boundary conditions: undefined data, empty array, data exactly equal to PAGE_SIZE, partial last page, page beyond data length, and non-numeric item types. This is the right level of rigor for a utility function.
• The NhrDocumentList pagination describe block correctly tests the first-page slice (Documents 1–20 shown, 21 hidden) and second-page navigation — these catch the most likely regression from incorrect getPagedData usage.
• Using mock components for child dependencies in NhrDocumentList.test.tsx is the correct approach — it isolates the component's own logic without coupling tests to design system internals.
• The controlled mode tests (lines 263–296) correctly verify that onApplyFilters is called externally rather than modifying internal state, and that external appliedFilters drives the filter count badge.
• The 'shows second page documents when page 2 is clicked' test (line 211) is well-structured: it simulates a real page navigation user event and asserts on both what appears (Documents 21, 25) and what disappears (Document 1).

Merge Recommendation

The PR is close to merge-ready but the gap in item 1 above (page reset via handleApplyFilters not being tested) is a real behavioral contract that the current test suite does not protect. Given that "reset to page 1 on filter apply" is explicit business logic in the implementation, it should have a test that directly exercises it. The fix is a single additional test case in the pagination describe block of NhrDocumentList.test.tsx.

Items 2–3 are improvements worth considering, but not blockers. Item 2 is worth adding given how easy it is to write and how meaningful the PAGE_SIZE wiring contract is.
