File: src/screens/OrganizationTags/OrganizationTags.test.tsx:184-0
Timestamp: 2024-11-12T10:40:58.655Z
Learning: In the `talawa-admin` project, it's acceptable for test cases in `src/screens/OrganizationTags/OrganizationTags.test.tsx` to test multiple behaviors within a single test function without needing to split them into smaller, focused tests.

File: src/screens/OrganizationTags/OrganizationTagsMocks.ts:384-524
Timestamp: 2025-01-15T05:39:30.480Z
Learning: In OrganizationTagsMocks.ts, MOCKS_NULL_END_CURSOR and MOCKS_NO_MORE_PAGES are designed to test UI handling of edge cases where pagination data is inconsistent (e.g., hasNextPage is true but endCursor is null, or next page returns undefined data).

Learning: In `src/screens/ManageTag/ManageTag.tsx`, the `DataGrid` component uses infinite scroll via `react-infinite-scroll`, and page-based pagination provided by `DataGrid` is not used.

Learning: In the `src/screens/OrganizationTags/OrganizationTags.tsx` file, the `OrganizationTags` component uses chunk size with the `InfiniteScroll` component and an outer parent div for handling data loading and scrolling.

Learning: In `src/screens/ManageTag/ManageTagMocks.ts`, when mocking data for `USER_TAGS_ASSIGNED_MEMBERS` and `USER_TAGS_MEMBERS_TO_ASSIGN_TO`, it's acceptable for user IDs to overlap because the queries serve different purposes and the overlapping IDs can represent realistic scenarios in tests.

🔇 Additional comments (10)
src/screens/OrganizationTags/OrganizationTags.spec.tsx (4)

305-322: LGTM! Comprehensive error handling test case.

The test case properly verifies that the error message from GraphQL is displayed to the user when tag creation fails.


323-331: LGTM! Empty state handling test.

The test case correctly verifies the "no tags found" message rendering when there are no tags.


332-342: LGTM! Edge case handling test.

The test case properly verifies that the component gracefully handles undefined userTagsList.


343-360: LGTM! Thorough pagination edge case tests.

The test cases properly verify the component's behavior when:

  1. endCursor is null but hasNextPage is true
  2. No more pages are available

These tests ensure robust handling of pagination edge cases.

Also applies to: 361-378

src/screens/OrganizationTags/OrganizationTags.tsx (3)

147-148: LGTM! Improved error handling.

Added explicit error handling for the case when tag creation fails but no error is thrown.


169-172: LGTM! Simplified null handling.

The fallback to an empty array when userTagsList is undefined is a clean solution.


363-363: LGTM! Enhanced testability.

Added data-testid attribute to InfiniteScroll component for better test coverage.

Also applies to: 371-371

src/screens/OrganizationTags/OrganizationTagsMocks.ts (3)

334-342: LGTM! Well-structured error mock.

The mock correctly simulates a GraphQL error during tag creation.


344-374: LGTM! Comprehensive empty state mock.

The mock properly represents an empty tags list with appropriate pageInfo.


391-475: LGTM! Thorough pagination edge case mocks.

The mocks effectively simulate:

  1. Null endCursor scenario
  2. No more pages scenario

These align with the retrieved learning about testing UI handling of inconsistent pagination data.

Also applies to: 477-531

    • I pushed a fix in commit <commit_id>, please review it.
    • Generate unit testing code for this file.
    • Open a follow-up GitHub issue for this discussion.
  • Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
    • @coderabbitai generate unit testing code for this file.
    • @coderabbitai modularize this function.
  • PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
    • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
    • @coderabbitai read src/utils.ts and generate unit testing code.
