Add Endorse Feature with Backend Functionality and Unit Tests

[rilical]

Overview

This pull request introduces the Endorse feature, enabling users to endorse and unendorse posts within the application. To ensure the reliability and robustness of this feature, comprehensive unit tests have been implemented for both backend and client-side components.

Features

1. Endorse Feature Implementation

• Backend Enhancements:

  • Posts Module (src/posts.js):
    • Added functions to handle endorsing and unendorsing posts.
    • Implemented logic to prevent users from endorsing their own posts.
    • Ensured endorsement counts are accurately tracked and updated.
  • Topics Module (src/topics.js):
    • Integrated endorsement functionality within the context of topics.
    • Updated topic data to reflect endorsement-related information.
  • API Routes (src/routes/api.js):
    • Created API endpoints for endorsing (PUT /posts/:pid/endorse) and unendorsing (DELETE /posts/:pid/endorse) posts.
    • Ensured proper authentication and authorization checks are in place for these endpoints.

• Client-Side Enhancements:

  • Post Tools (public/src/client/topic/postTools.js):
    • Added endorse button functionality that interacts with the backend API.
    • Implemented UI updates to reflect the endorsement status of posts.

2. Unit Tests

• Server-Side Tests (test/posts.js and test/topics.js):

  • Endorse Feature Tests:
    • test/posts.js:
      • Endorsing a Post: Verifies that a user can successfully endorse a post.
      • Unendorsing a Post: Ensures that a user can remove their endorsement.
      • Endorsement Count: Checks that endorsement counts are accurately incremented and decremented.
      • Endorsement Privileges: Confirms that only authorized users can endorse posts.
      • API Endpoints: Tests the /posts/:pid/endorse PUT and DELETE endpoints for correct behavior and error handling.
    • test/topics.js:
      • Endorsement in Topic Context: Validates that endorsements are correctly associated within topics.
      • Endorsed Posts in Listings: Ensures that endorsed posts appear appropriately in topic listings.
      • Endorsed Post Sorting: Verifies that endorsed posts are sorted correctly when sorting options are enabled.

• Client-Side Tests (test/topic/endorse.js):

  • Endorse Button Functionality: Tests that clicking the endorse button triggers the correct API call.
  • UI Updates: Ensures that the UI reflects the endorsed state after an endorsement action.
  • API Call Handling: Checks that successful endorsements and errors are handled gracefully, providing appropriate user feedback.
