📋 Test Files

1. test_embedding_cache.cpp (15+ tests)

Compliance:

#include <gtest/gtest.h>

class EmbeddingCacheTest : public ::testing::Test {
protected:
    void SetUp() override {
        // Setup code using Google Test fixture pattern
    }
    
    void TearDown() override {
        // Cleanup code
    }
    
    std::unique_ptr<EmbeddingCache> cache;
};

TEST_F(EmbeddingCacheTest, StoreAndRetrieve) {

        // Initialize query engine, context
    }
};

TEST_F(RecursiveCTETest, OrgHierarchyTraversal) {
    ASSERT_NE(result, nullptr);
    EXPECT_GT(result->size(), 0);
    EXPECT_EQ((*result)[0]["name"], "CEO");
}

    }
};

TEST_F(DistributedTransactionTest, TwoPhaseCommitSuccess) {
    ASSERT_TRUE(success);
    EXPECT_EQ(coordinator.getStatus(txn_id), Status::COMMITTED);
}

TEST_F(DistributedTransactionTest, ConcurrentTransactions) {
    // Multi-threaded test using Google Test
    std::vector<std::thread> threads;
    for (int i = 0; i < 10; ++i) {
        threads.emplace_back([&]() {
            // Test code
        });
    }
    for (auto& t : threads) t.join();
}

// Embedding Cache Benchmark
static void BM_EmbeddingCache_Store(benchmark::State& state) {
    cache::EmbeddingCache::Config config;
    config.max_entries = 10000;
    cache::EmbeddingCache cache(config);
    
    const int dim = state.range(0);

    for (auto _ : state) {
        // Benchmark code
    }
    
    state.SetItemsProcessed(state.iterations());

• Support XML output for CI/CD

Benchmarks

• Use #include <benchmark/benchmark.h>

• Compatible with Google Benchmark CLI options

Build System

• Use find_package(GTest CONFIG REQUIRED)
• Link with GTest::gtest and GTest::gtest_main
• Use find_package(benchmark REQUIRED)
• Link with benchmark::benchmark
