Overview

The major design changes in PR #48 introduced new runtime and reporting modules that need comprehensive test coverage.

Missing Test Coverage

1. Runtime Module Tests

• mcp_fuzzer/fuzz_engine/runtime/manager.py - ProcessManager class
• mcp_fuzzer/fuzz_engine/runtime/watchdog.py - ProcessWatchdog class
• mcp_fuzzer/fuzz_engine/runtime/wrapper.py - AsyncProcessWrapper and AsyncProcessGroup

2. Reporting System Tests

• mcp_fuzzer/reports/reporter.py - FuzzerReporter class
• mcp_fuzzer/reports/formatters.py - ConsoleFormatter, JSONFormatter, TextFormatter
• mcp_fuzzer/reports/safety_reporter.py - SafetyReporter class

3. Integration Tests

• End-to-end testing of watchdog + process management
• Reporter integration with safety system
• CLI argument handling for new reporting options
• Cross-platform process management (Windows/Unix)

4. Edge Case Testing

• Process hanging scenarios and watchdog intervention
• Resource exhaustion during fuzzing
• Signal handling across platforms
• Malformed report data handling

Acceptance Criteria

• Add unit tests for ProcessManager with >90% coverage
• Add unit tests for ProcessWatchdog including timeout scenarios
• Add tests for AsyncProcessWrapper and AsyncProcessGroup
• Add comprehensive tests for all reporter classes
• Add integration tests for runtime + reporting
• Add cross-platform testing for process management
• Add performance/stress tests for long-running scenarios
