Verbose Output

./build_install/bin/playerbot_tests --gtest_filter="BehaviorManagerTest.*" --gtest_color=yes

gdb --args ./build_install/bin/playerbot_tests --gtest_filter="BehaviorManagerTest.ErrorHandling_ExceptionInOnUpdate_DisablesManager"
(gdb) run
(gdb) bt

With Valgrind

valgrind --leak-check=full --show-leak-kinds=all ./build_install/bin/playerbot_tests --gtest_filter="BehaviorManagerTest.*"

Known Limitations

1. Mock Objects: MockPlayer and MockBotAI are minimal implementations

   • Do not test actual TrinityCore integration
   • Integration tests should be created separately

2. Timing Variance: Performance tests may show variance on different systems

   • Tests allow reasonable tolerance
   • Run multiple times to verify consistency

3. Platform Differences: Threading behavior may differ

   • All tests designed to be platform-agnostic
   • Sanitizers may not work on Windows

Future Enhancements

• Integration tests with real TrinityCore Player objects
• Stress tests with 1000+ managers concurrently
• Fuzzing tests for edge case discovery
• Property-based testing for throttling logic
• Visual performance profiling reports
• Tests for derived manager classes (QuestManager, CombatManager, etc.)

   RUN_BEHAVIORMANAGER_TESTS.bat all   # Windows
   

3. Verify Coverage

   ./RUN_BEHAVIORMANAGER_TESTS.sh coverage  # Linux only
   

Integration into Development Workflow

1. Add to CI/CD Pipeline

   • Configure GitHub Actions or Jenkins
   • Run tests on every pull request
   • Fail build if tests fail

2. Code Review

   • Require all new BehaviorManager changes to update tests
   • Maintain 90%+ coverage requirement

3. Create Derived Class Tests

   • Use BehaviorManagerTest as template
   • Create tests for QuestManager, CombatManager, etc.
   • Follow same quality standards
