# BD-29T: ActivityStream E2E Test

## Task
Create a vitest test that verifies ActivityStream component displays log entries in chronological order with proper timestamps, level colors, scrolling behavior, and filtering.

## Status
**Already Complete** - The E2E test already exists at `src/web/frontend/components/ActivityStream.e2e.test.tsx` and comprehensively covers all requirements.

## Test Coverage
The existing test includes 20 test cases across 6 categories:

### 1. Chronological Order (3 tests)
- Renders events in the order provided
- Handles 100+ events in correct order
- Preserves order across mixed log levels

### 2. Timestamp Formatting (2 tests)
- Formats timestamps as HH:MM:SS (24-hour)
- Displays distinct timestamps for distinct events

### 3. Level Colors (3 tests)
- Applies correct CSS class for each log level (debug, info, warn, error)
- Displays level text matching the level value
- Colors mixed event streams correctly

### 4. Scrolling Behavior (4 tests)
- Auto-scrolls to bottom when events change
- Handles multiple events arriving at once
- Scrolls to timeline-highlighted event
- Removes timeline-highlight after 3 seconds

### 5. Filtering (4 tests)
- Shows filter controls when enabled
- Shows "No events match" message when filter excludes all
- Displays filtered event count in header
- Distinguishes empty vs filtered-empty states

### 6. Complete Display Workflow (4 tests)
- Renders realistic multi-worker event stream
- Hides worker names when specific worker selected
- Auto-scrolls on each event update
- Handles bead pinning display

## Test Results
All 20 tests pass:
```
✓ src/web/frontend/components/ActivityStream.e2e.test.tsx (20 tests) 183ms
```

## Conclusion
No code changes were required. The existing E2E test suite fully satisfies the task requirements.
