Walkthrough

The pull request introduces modifications to the analytics handling in the end-to-end tests. In the analytics support file, a new private property, lastRequestCount, is added to track the number of processed requests. Two new methods are introduced: one for finding the latest request by a specific event type and another for waiting until a specified number of new requests are processed. An existing method, extractRequestTypes, is removed. The test files are updated to utilize the new methods for waiting and retrieving analytics requests instead of directly accessing the requests array. This ensures that assertions are made only after the expected number of requests has been processed. Additionally, optional chaining is implemented to enhance error handling for potentially undefined values.

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.

107-114: Consider adding test coverage for edge cases.

The test verifies the happy path but could benefit from additional coverage:

  • Test behavior when analytics events fail to arrive
  • Test behavior with concurrent analytics events
  • Test behavior with duplicate events
packages/suite-desktop-core/e2e/tests/analytics/events.test.ts (1)

41-47: Document the expected event sequence.

While the code correctly waits for 3 events, the magic number could be more explicit.

Apply this diff to improve code clarity:

-        await analytics.waitForAnalyticsRequests(3);
+        // Wait for the initial sequence of events:
+        // 1. suite-ready
+        // 2. device-connect
+        // 3. transport-type
+        const EXPECTED_INITIAL_EVENTS = 3;
+        await analytics.waitForAnalyticsRequests(EXPECTED_INITIAL_EVENTS);

❓ Verification inconclusive

Address the TODO comment.

The TODO comment references issue #15811 for refactoring. Let's verify if this issue is still relevant.


🏁 Script executed:

#!/bin/bash
# Check if the referenced issue exists and is still open
gh issue view 15811

Length of output: 110


Action Required: Verify the Status of Issue #15811

The TODO in packages/suite-desktop-core/e2e/support/analytics.ts (line 19) still references issue #15811 for refactoring. The automated check using gh issue view 15811 failed because the repository context was not recognized as a Git repository, so its current status couldn’t be confirmed automatically.

File: packages/suite-desktop-core/e2e/support/analytics.ts (line 19)
Issue Reference: #15811

Recommended next steps:
Please manually verify if issue #15811 is still open or relevant. Based on that confirmation, update the TODO comment accordingly (e.g., remove, update, or address the refactor details).

packages/suite-desktop-core/e2e/tests/analytics/toggle.test.ts (1)

24-35: LGTM! Improved test reliability.

The changes enhance test reliability by:

  • Using waitForAnalyticsRequests to ensure events are captured
  • Using optional chaining for safer property access
  • Using type-safe event lookups with findLatestRequestByType
packages/suite-desktop-core/e2e/tests/analytics/events.test.ts (1)

77-78: LGTM! Race condition fix.

The changes properly handle the device disconnect event by:

  • Waiting for the event using waitForAnalyticsRequests
  • Using type-safe findLatestRequestByType for verification

⚠️ Potential issue

Fix array mutation in findLatestRequestByType.

The current implementation mutates the original array by using reverse(). This could affect other code that relies on the array order.

Apply this diff to create a non-mutating implementation:

-    findLatestRequestByType(eventType: SuiteAnalyticsEvent['type']) {
-        return this.requests.reverse().find(req => req.c_type === eventType)
+    findLatestRequestByType(eventType: SuiteAnalyticsEvent['type']) {
+        return [...this.requests].reverse().find(req => req.c_type === eventType)
📝 Committable suggestion

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Suggested change
findLatestRequestByType(eventType: SuiteAnalyticsEvent['type']) {
return this.requests.reverse().find(req => req.c_type === eventType)
}
findLatestRequestByType(eventType: SuiteAnalyticsEvent['type']) {
return [...this.requests].reverse().find(req => req.c_type === eventType)
}
