Add average daily activity calculation with command and REST API #69

Copilot · 2025-12-12T08:48:45Z

Average Daily Activity Feature - COMPLETE ✅

All requirements from the issue have been successfully implemented and tested.

✅ Features Implemented

Command Interface: /at average [playerName] [days]
- Default period: 7 days (as requested)
- Optional player name parameter
- Optional days parameter for custom periods
- Displays both total hours in period and average hours per day
- Permission: at.average (default: true)
REST API Endpoint: GET /api/average-daily-activity/{uuid}?days=X
- Player UUID path parameter
- Optional days query parameter (default: 7)
- Returns JSON with player info, period, and statistics
- Proper error handling for invalid inputs
Accurate Calculation
- Filters sessions within the specified time period
- Handles both active and completed sessions
- Uses !isBefore() for inclusive date comparison (with clarifying comment)
- Separate method for total hours calculation (not just average * days)

📝 Changes Summary

Code Improvements:

Fixed NumberFormatException handling in AverageCommand to return false instead of continuing with default
Added clarifying comment for date filtering logic in ActivityRecordService
Enhanced AverageDailyActivityTest with comprehensive test using real session data with specific timestamps
Added 5 new REST API tests covering serialization, data retrieval, invalid inputs, and different time periods
Optimized test code: reusing Gson instance and using unique session IDs

Test Coverage:

Service tests now validate actual calculation with sessions at different dates (3, 5, 10 days ago)
Tests verify correct filtering (10-day-old session excluded from 7-day period)
REST API tests cover valid requests, serialization, invalid days, player not found, and multiple periods
Total of 12 test methods across service and API tests

🔒 Security & Quality

✅ All PR review comments addressed
✅ No security vulnerabilities (CodeQL scan passed)
✅ Comprehensive test coverage with realistic scenarios
✅ Clear, documented code with explanatory comments
✅ Efficient test implementation (reusing resources, unique IDs)

src/test/java/dansplugins/activitytracker/services/AverageDailyActivityTest.java

+    @Test
+    public void testCalculateAverageDailyActivity_WithCompletedSessions() {
+        UUID playerUuid = UUID.randomUUID();
+        Session session = sessionFactory.createSession(playerUuid);
+        ActivityRecord record = new ActivityRecord(playerUuid, session);
+
+        // Clear the initial session
+        record.getSessions().clear();
+
+        // We can't easily test with real sessions without mocking LocalDateTime
+        // So we just verify the method doesn't crash with a valid record
+        double average = activityRecordService.calculateAverageDailyActivity(record, 7);
+
+        // Should be 0 since there are no sessions
+        assertEquals(0.0, average, 0.01);
+    }


This test doesn't effectively validate the calculation logic with actual data. The test creates a record, clears all sessions, and then verifies the result is 0.0, which is essentially the same as the "NoSessions" test. Consider adding a test that creates sessions with specific timestamps and validates that the calculation correctly filters sessions based on the cutoff date and properly sums the hours.

Fixed in commit 5d4b940. The test now creates sessions with specific timestamps (3, 5, and 10 days ago) and validates that:

Sessions within the 7-day period (3 and 5 days ago) are correctly included

Sessions outside the period (10 days ago) are excluded

Total hours and averages are calculated accurately for both 7-day and 30-day periods

+            );
+
+            return gson.toJson(avgResponse);
+        });


The REST API endpoint for average daily activity lacks test coverage. The RestApiServiceTest file contains tests for other endpoints (stats, leaderboard, player data), but there are no tests for the new average-daily-activity endpoint. Consider adding tests to verify the endpoint handles valid requests, invalid UUIDs, missing players, and invalid days parameters correctly.

Fixed in commit 5d4b940. Added 5 comprehensive tests covering:

Response serialization/deserialization

Valid data retrieval for average daily activity

Invalid days parameter handling (0, negative)

Player not found scenario

Different time periods (7 days vs 30 days)

Copilot · 2025-12-12T10:44:24Z

src/main/java/dansplugins/activitytracker/services/ActivityRecordService.java

+        double totalHours = 0.0;
+
+        // Sum up hours from sessions within the time period
+        for (Session session : record.getSessions()) {


The date filtering logic uses 'not isBefore' to include sessions on or after the cutoff date. While this works correctly for including sessions from exactly N days ago, it might be clearer to use 'isAfter or isEqual' semantics. However, since LocalDateTime doesn't have an isAfterOrEqual method, consider using 'isAfter(cutoffDate.minusNanos(1))' or add a comment explaining that '!isBefore(cutoffDate)' means 'on or after cutoffDate' to improve code readability.

Suggested change

for (Session session : record.getSessions()) {

for (Session session : record.getSessions()) {

// !isBefore(cutoffDate) means "on or after cutoffDate"

Fixed in commit 5d4b940. Added clarifying comment: // !isBefore(cutoffDate) means "on or after cutoffDate" - includes sessions from exactly N days ago

src/main/java/dansplugins/activitytracker/commands/AverageCommand.java

+                sender.sendMessage(ChatColor.RED + "Invalid number of days. Using default: " + DEFAULT_DAYS);
+                days = DEFAULT_DAYS;


When a NumberFormatException is caught for invalid days parameter, the code sends an error message but then continues execution with the default value instead of returning false. This creates inconsistent behavior - the error message says the days parameter is invalid, but the command succeeds anyway. Consider returning false after sending the error message to maintain consistency with other validation errors in the same method.

Suggested change

sender.sendMessage(ChatColor.RED + "Invalid number of days. Using default: " + DEFAULT_DAYS);

days = DEFAULT_DAYS;

sender.sendMessage(ChatColor.RED + "Invalid number of days.");

return false;

Fixed in commit 5d4b940. Changed to return false immediately after sending the error message, maintaining consistency with other validation errors.
