There are 3 ways to chat with CodeRabbit:

  • Review comments: Directly reply to a review comment made by CodeRabbit. Example:
    • 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.

    • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

Line range hint 17-181: Consider extracting mock data to a separate file.

The mock data is quite extensive and could be better organized by moving it to a separate file (e.g., __mocks__/orgPostMocks.ts). This would improve maintainability and make the test file more focused on test cases.


182-273: Enhance pagination mocks for better test coverage.

The pagination mocks could be improved in two ways:

  1. Include actual post data in the edges array instead of empty arrays to test data rendering
  2. Use more meaningful cursor values that reflect the actual data structure
 const nextPageMock = {
   // ... other properties
   result: {
     data: {
       organizations: [{
         posts: {
-            edges: [],
+            edges: [{
+              node: {
+                _id: 'post2',
+                title: 'Second Post',
+                text: 'Content for second post',
+                // ... other post properties
+              },
+              cursor: 'post2'
+            }],
             pageInfo: {
-              startCursor: 'startCursor2',
-              endCursor: 'endCursor2',
+              startCursor: 'post2',
+              endCursor: 'post2',
               // ... other pageInfo properties
             }
         }
       }]
     }
   }
 };

957-1026: Improve pagination test descriptions and assertions.

The pagination test cases could be more specific about what they're testing. Also, consider adding assertions to verify the actual data changes when navigating between pages.

- it('pagination controls work correctly', async () => {
+ it('should load next page of posts when clicking next button', async () => {
   // ... test code
+  // Add assertions to verify the actual posts changed
 });

- it('pagination buttons states are correctly set', async () => {
+ it('should disable pagination buttons when no more pages are available', async () => {
   // ... test code
 });

Also applies to: 1028-1084


1151-1191: Add more specific error test cases.

The error handling test case could be expanded to cover more specific error scenarios:

  • Invalid title length
  • Invalid content type
  • Server errors

🛠️ Refactor suggestion

Consolidate duplicate test cases.

These test cases test similar functionality (image upload and preview). Consider combining them into a single, comprehensive test case with multiple assertions.

- it('handleAddMediaChange: uploading a file and verifying the preview', async () => {
-   // ... test code
- });

- it('Create post and preview', async () => {
-   // ... similar test code
- });

+ it('handles media upload, preview, and removal correctly', async () => {

+   // Test image upload

💡 Codebase verification

Fix undefined organizationId in success mock.

The organizationId is marked as non-nullable (ID!) in the CREATE_POST_MUTATION definition, but the success mock uses undefined. This will cause the mutation to fail at runtime. The mock should use a valid ID value like other tests in the codebase (e.g., '123').

🔗 Analysis chain

Fix undefined organizationId in success mock.

The success mock has organizationId: undefined which might not accurately represent the real-world scenario where an organization ID is required for post creation.

🏁 Scripts executed

The following scripts were executed for the analysis:

Script:

#!/bin/bash
# Check if organizationId is required in the actual mutation
ast-grep --pattern 'mutation createPost($organizationId: ID!) {
  $$$
}'

Length of output: 74


Script:

#!/bin/bash
# Find the CREATE_POST_MUTATION definition
rg "CREATE_POST_MUTATION" -A 5

# Also search for createPost mutation with a more flexible pattern
ast-grep --pattern 'mutation createPost($_) {
  $$$
}'

Length of output: 6958


Script:

#!/bin/bash
# Get the complete CREATE_POST_MUTATION definition
rg -A 15 "export const CREATE_POST_MUTATION = gql`"
