Summary

Fix 4 disabled test files that require Result API updates to restore test coverage. This is Phase 1 of ARC-001 (Low Test Coverage) resolution.

Related Architecture Issue

• ARC-001: Low Test Coverage (65% → 80% target)
• Phase 1 focuses on Result API migration tests

Current State

Location: tests/CMakeLists.txt:105-117

The following tests are disabled due to Result API changes:

Problem Analysis

API Migration Required

The codebase migrated from:

// Old pattern
result<T> res = some_function();
if (res) { auto val = res.value(); }

To:

// New pattern (common::Result<T>)
common::Result<T> res = some_function();
if (res.is_ok()) { auto val = res.value(); }

Missing Type: monitoring_data

Some tests reference monitoring_data type which was removed or renamed during API evolution.

Tasks

• Update test_health_monitoring.cpp to use is_ok() / is_err() pattern
• Update test_fault_tolerance.cpp to use new Result API
• Identify replacement for monitoring_data type in test_metric_exporters.cpp
• Update test_opentelemetry_adapter.cpp for new API
• Enable all 4 tests in tests/CMakeLists.txt
• Verify all tests pass

Acceptance Criteria

• All 4 test files compile successfully
• All tests in these files pass
• Tests added back to tests/CMakeLists.txt
• CI passes on all platforms

Priority

P0 (High) - Critical for test coverage improvement (ARC-001)

Migration Pattern Reference

// Before (deprecated)
auto result = health_monitor.check();
EXPECT_TRUE(result);
auto value = result.value();

// After (current API)
auto result = health_monitor.check();
EXPECT_TRUE(result.is_ok());
auto value = result.value();

// Error handling
if (result.is_err()) {
    auto& error = result.error();
    // handle error
}
