Walkthrough

The pull request refactors the Requests.spec.tsx test file to integrate the vitest testing framework, replacing Jest-specific functions with Vitest equivalents. It includes mocking of localStorage and window.location for improved test isolation and reliability. Additionally, a new asynchronous utility function wait is introduced to facilitate timing control in tests. The overall structure of the tests remains consistent, covering various scenarios related to user roles and data rendering.

Poem

🐇 In the land of tests, so bright and fair,
Vitest hops in with a joyful flair.
Mocking and waiting, all done with glee,
Asynchronous magic, just wait and see!
With coverage intact, our tests will thrive,
In the world of code, we come alive! 🌟

🪧 Tips

Chat

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 read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
    • @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.

29-34: Enhance localStorage mock implementation

While the basic mock structure is correct, consider enhancing it with return values and type safety:

-vi.stubGlobal('localStorage', {
-  getItem: vi.fn(),
-  setItem: vi.fn(),
-  clear: vi.fn(),
-  removeItem: vi.fn(),
-});
+vi.stubGlobal('localStorage', {
+  getItem: vi.fn().mockImplementation((key: string) => null),
+  setItem: vi.fn().mockImplementation((key: string, value: string) => undefined),
+  clear: vi.fn().mockImplementation(() => undefined),
+  removeItem: vi.fn().mockImplementation((key: string) => undefined),
+} as Storage);

40-50: Enhance window.location mock with type safety

Consider adding type safety to the window.location mock:

-Object.defineProperty(window, 'location', {
+const mockLocation: Partial<Location> = {
+  href: 'http://localhost/',
+  assign: vi.fn(),
+  reload: vi.fn(),
+  pathname: '/',
+  search: '',
+  hash: '',
+  origin: 'http://localhost',
+};
+
+Object.defineProperty(window, 'location', {
   value: {
-    href: 'http://localhost/',
-    assign: vi.fn(),
-    reload: vi.fn(),
-    pathname: '/',
-    search: '',
-    hash: '',
-    origin: 'http://localhost',
+    ...mockLocation,
   },
+  writable: true
 });

62-69: Enhance wait utility with timeout handling

The wait utility is well documented, but consider adding timeout handling for better test reliability:

 /**
  * Utility function to wait for a specified amount of time.
  * Wraps `setTimeout` in an `act` block for testing purposes.
  *
  * @param ms - The duration to wait in milliseconds. Default is 100ms.
+ * @throws {Error} If the timeout is exceeded
  * @returns A promise that resolves after the specified time.
  */
-async function wait(ms = 100): Promise<void> {
+async function wait(ms = 100, timeout = 5000): Promise<void> {
+  const controller = new AbortController();
+  const timeoutId = setTimeout(() => controller.abort(), timeout);
+
   await act(() => {
     return new Promise((resolve) => {
-      setTimeout(resolve, ms);
+      const timer = setTimeout(resolve, ms);
+      controller.signal.addEventListener('abort', () => {
+        clearTimeout(timer);
+        throw new Error(`Wait operation timed out after ${timeout}ms`);
+      });
     });
   });
+  
+  clearTimeout(timeoutId);
 }

Line range hint 1-300: Overall test migration to Vitest looks good

The migration from Jest to Vitest has been well executed with:

  • Proper use of Vitest mocking utilities
  • Comprehensive test coverage maintained
  • Good async/await handling with act
  • Well-structured test cases

Consider adding the following to the test suite:

  • Test cleanup in afterEach to reset vi.mocks()
  • Explicit typing for mock data
+afterEach(() => {
   localStorage.clear();
+  vi.clearAllMocks();
 });

23-24: LGTM: Vitest import is correctly added

The import of vi from 'vitest' is appropriate for the test migration.

We have a policy of unassigning contributors who close PRs without getting validation from our reviewer team. This is because:

  1. We start looking for people to review PRs when you submit them.
  2. We often contact them and link to the PR. If the PR is closed the whole effort is wasted.
  3. The historical thread of reviewer comments is broken when the work is spread across multiple PRs. The quality of our code is affected negatively.

Please be considerate of our volunteers' limited time and our desire to improve our code base.

This policy is stated as a pinned post in all our Talawa repositories. Our YouTube videos explain why this practice is not acceptable to our Community.

Unfortunately, if this continues we will have to close the offending PR and unassign you from the issue.

@palisadoes Extremely sorry for the act..the only reason for closing of PRs is that it fails many CI tests..Hence , to make the PR pass the CI tests, I have chose to close my PRs and open new one so that it is ready to be merged..this PR is ready to be merged..And I will make sure strictly this won't happen again
