Improve event emitter and add tests #2

Closed sweep-ai[bot] closed 2 weeks ago

sweep-ai[bot] commented 2 weeks ago

This pull request was created by Sweep to resolve the following request by @harperreed:

Add comprehensive unit tests for the internal/events package

Definition of Complete

  • A new test file events_test.go is created in the internal/events directory.
  • Unit tests are implemented for all exported functions and methods in the events.go file.
  • Test coverage for the internal/events package is at least 80%.

What Should be Done

  1. Create a new file internal/events/events_test.go.
  2. Implement the following test functions in events_test.go:
    • TestNewEventEmitter
    • TestEventEmitter_On
    • TestEventEmitter_Emit
    • TestGetEventType
  3. Write test cases that cover different scenarios for each function, including:
    • Normal operation
    • Edge cases (e.g., emitting an unknown event type)
    • Concurrent access to the EventEmitter
  4. Update the internal/events/events.go file to export the getEventType function if necessary for testing.
  5. Ensure all tests pass an

Purpose

This pull request aims to improve the event emitter implementation and add comprehensive tests to ensure its reliability and correctness.

Description

The changes in this pull request include:

  1. Renaming the getEventType function to GetEventType to make it publicly accessible.
  2. Adding a new test file events_test.go that includes the following tests:
    • TestNewEventEmitter: Ensures that the NewEventEmitter function returns a valid event emitter instance.
    • TestEventEmitter_On: Verifies that the On method correctly adds a listener for a given event type.
    • TestEventEmitter_Emit: Checks that the Emit method correctly triggers the registered listeners for a given event.
    • TestEventEmitter_EmitUnknownType: Ensures that emitting an event with an unknown type does not cause a panic.
    • TestEventEmitter_ConcurrentAccess: Tests the event emitter's ability to handle concurrent access, with multiple goroutines adding listeners and emitting events.
    • TestGetEventType: Verifies the behavior of the GetEventType function for different event types.

Walkthrough

The changes involve renaming the getEventType function to GetEventType, making it accessible from outside the package. Additionally, a new test file events_test.go has been introduced, containing a suite of unit tests for the EventEmitter functionality, which includes tests for listener registration, event emission, and concurrent access handling.

Changes

Files Change Summary
internal/events/events.go Renamed getEventType to GetEventType, changing its accessibility from unexported to exported.
internal/events/events_test.go Introduced unit tests for EventEmitter, validating listener registration, event emission, and concurrency.

🐰 "Oh, what a change, so bright and new,
GetEventType shines, it's true!
With tests in place, we leap and bound,
Ensuring events are safe and sound.
Hops of joy in code we see,
A happy rabbit, full of glee!" 🐇✨

Tips ### Chat There are 3 ways to chat with [CodeRabbit](https://coderabbit.ai): - Review comments: Directly reply to a review comment made by CodeRabbit. Example: - `I pushed a fix in commit .` - `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 generate interesting stats about this repository and render them as a table.` - `@coderabbitai show all the console.log statements in this repository.` - `@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. ### CodeRabbit Commands (Invoked using PR comments) - `@coderabbitai pause` to pause the reviews on a PR. - `@coderabbitai resume` to resume the paused reviews. - `@coderabbitai review` to trigger an incremental review.
