259-262: Loading indicator is well-labeled but consider more nuanced states.Introducing a
data-testid="loading-state"is helpful for testing. You may consider showing partial results or a skeleton for better UX if loading takes longer.
273-273: Consider clarifying conditional logic for row slicing.Splitting donations via
rowsPerPage > 0 ? ... : donationsis functional but could be more readable. A small helper function might make the logic clearer if it expands over time.src/screens/UserPortal/Donate/Donate.spec.tsx (2)
235-253: Search input test is simple yet effective.You're verifying the field can receive user input. Potential improvement: test search result filtering if functionality is implemented.
332-351: Search button presence test looks correct.You confirm the button remains enabled and present. As a future enhancement, verify that clicking it triggers search side effects if any exist.

Line range hint 128-151: Convert to async function looks good, but consider thorough validation coverage.
Using async / await in donateToOrg is a solid approach for better error handling. The numeric and range validations are comprehensive. Ensure your tests cover all branches, including boundary checks (e.g., exactly 1, exactly 10000000) and potential floating-point input.
152-152: Await the donation mutation for a safer sequence of operations.
Awaiting donate before calling refetch ensures data consistency. Good job! Verify all calls to donateToOrg are now properly awaited if needed elsewhere in the code.
Line range hint 299-303: PaginationList usage is correct; watch out for edge cases.
Passing donations.length is fine. Just ensure calling components handle 0 safely. This aligns with your test for when rowsPerPage is 0 (show all items).
src/screens/UserPortal/Donate/Donate.spec.tsx (22)
8-8: Importing the essential testing utilities is appropriate.
These imports allow comprehensive testing of the Donate component. Ensure you remove any unused imports if your linter flags them.
26-31: Mocking the error handler is a solid approach.
Mocking errorHandler clarifies your error test scenarios. Reuse this pattern for other modules that might need mocking.
166-167: Mocking matchMedia is good for consistent environment in tests.
This ensures your component won't break under media-related conditions. Keep an eye on potential changes if your component grows in responsive complexity.
197-213: Test for updating donation amount is thorough.
Verifying user input with fireEvent is crucial. Consider also testing boundary values (e.g., zero, negative, etc.) within the same test or separate tests if you want stricter isolation.
215-234: Test coverage for currency dropdown is comprehensive.
The click and text assertions confirm correct state updates. Good job ensuring coverage for the currency switch logic.
255-271: Pagination list rendering test ensures the table structure is present.
Confirm additional behaviors (prev/next page clicks) are also tested in other blocks. This test alone is a good starting point.
272-291: Row changes test for pagination is detailed.
This accurately verifies that changing rows per page updates the UI. Good coverage for user-driven pagination events.
292-331: Verifying the correct number of cards on each page is essential.
Checking that only 5 donation cards render by default is an important coverage scenario. Well done.
352-370: Verification of initial donation form elements is strong.
Ensuring the correct default states for selected currency, input values, and the donate button readiness is key to a robust identity check.
371-390: Loading state test confirms your spinner’s visibility.
Checking data-testid="loading-state" is a best practice for ensuring test stability. This is especially important for asynchronous data retrieval.
391-426: Empty donations test ensures a fallback message.
You validate that nothing to show renders properly. This is a good user-facing scenario often missed in coverage.
Line range hint 427-464: Currency switching tests for USD, INR, EUR are consistent.
Testing each currency carefully ensures thorough coverage and confidence that the UI updates properly for each selection.
634-658: Whitespace trimming test is a critical edge case.
Using type(screen.getByTestId('donationAmount'), ' 123 ') ensures your function handles leading/trailing spaces properly. Good catch!
660-692: Tests for null donation data confirm graceful fallback.
You confirm if donation data is null, the UI displays nothing to show. This robustly handles potential unexpected backend responses.
693-714: Zero rowsPerPage scenario tests the show-all logic.
Ensuring the UI displays all donations when rowsPerPage is zero is a nuanced scenario. Great job capturing it in a test.
715-736: Empty donation amount test for donateToOrg is thorough.
Verifying that the error toast appears covers a critical edge case. Good coverage for form validation.
737-781: Page update test ensures next-page is functional.
Clicking the “next” button and verifying the new set of donation cards underscores robust navigation coverage.
782-803: Non-numeric amount test properly triggers an error toast.
Verifying that an error appears for non-numeric input in donationAmount ensures reliability in user input handling.
805-826: Minimum donation enforcement test is correct.
Users who enter amounts below the threshold see the correct error message, fulfilling real-world validation.
828-849: Maximum donation threshold test prevents overly large amounts.
Ensuring out-of-range inputs produce a clear error adds to the trustworthiness of the donation flow.
851-901: Test coverage for donation mutation error ensures graceful failure handling.
You’ve correctly mocked the mutation error scenario. Confirm users are informed about the failure and any retry mechanisms if needed.
903-952: GraphQL error scenario test is thorough.
Similar to the previous scenario, verifying that GraphQL-level errors also trigger the error handler ensures robust resilience in distributed systems.
