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.
