+# CSV Export Functional Test
+
+This directory contains the automated functional test for CSV export generation with the Poliris bundle.
+
+## Overview
+
+The functional test validates that the Poliris bundle correctly generates CSV export files for real estate properties without requiring a database. It uses mock JSON data to simulate real-world scenarios.
+
+## Test Structure
+
+### Mock Data File
+- **Location**: `tests/Fixtures/mock-properties.json`
+- **Content**: 3 simulated real estate properties:
+  1. **House for Sale** - Paris, €750,000
+  2. **Apartment for Rent** - Lyon, €1,200/month
+  3. **Land for Sale** - Bordeaux, €180,000
+
+Each property includes realistic data:
+- Identifiant (agency ID, reference, type, technical ID)
+- Type (property type and subtype)
+- Localisation (address, city, postal code, coordinates, proximity info)
+- Prix (price, pricing details)
+- Surface (living space, land area, room sizes)
+- Contact (name, phone, email, website)
+- Detail (title, description)
+- Photos (URLs and titles)
+- Additional fields (location/rental info, land details, etc.)
+
+### Test File
+- **Location**: `tests/Functional/CsvExportFunctionalTest.php`
+- **Test Methods**:
+  1. `it_generates_complete_csv_export_with_property_data()` - Main test validating full CSV generation with all fields
+  2. `it_generates_empty_csv_when_no_properties()` - Tests empty export handling
+  3. `it_validates_csv_structure_and_format()` - Validates Poliris CSV structure
+  4. `it_contains_expected_values_from_mock_data()` - Verifies specific data values in CSV
+
+## What the Test Validates
+
+✅ **File Generation**: CSV file is created successfully  
+✅ **File Content**: CSV is not empty and contains data  
+✅ **Line Count**: Correct number of lines (one per property)  
+✅ **Poliris Format**: Uses correct delimiter format (`"field"!`)  
+✅ **Field Count**: Each line has 100+ columns (Poliris format has 333+ columns)  
+✅ **Data Integrity**: All expected values (prices, addresses, references) are present  
+✅ **Structure**: Validates proper CSV parsing and field extraction
+
+## Running the Test Locally
+
+```bash
+# Install dependencies
+composer install
+
+# Run the CSV export functional test
+composer test tests/Functional/CsvExportFunctionalTest.php
+
+# Or using PHPUnit directly
+vendor/bin/simple-phpunit tests/Functional/CsvExportFunctionalTest.php --testdox
+```
+
+## GitHub Actions Integration
+
+The test runs automatically via the **CSV Export Functional Test** workflow (`.github/workflows/csv-export-test.yml`):
+
+- **Trigger**: On every push and pull request
+- **PHP Versions**: 8.2 and 8.3
+- **Symfony Version**: 7.0.*
+- **Steps**:
+  1. Checkout code
+  2. Setup PHP environment
+  3. Install dependencies via Composer
+  4. Verify mock data file exists
+  5. Run functional test with detailed output
+  6. Display test summary
+
+## Adding New Test Cases
+
+To add more test properties to the mock data:
+
+1. Edit `tests/Fixtures/mock-properties.json`
+2. Add a new property object with the required fields
+3. Update the test assertions if needed (e.g., line count)
+4. Run the tests locally to verify
+
+Example minimal property:
+```json
+{
+  "identifiant": {
+    "agenceId": "AGENCY_ID",
+    "agencePropertyRef": "REF",
+    "annonceType": "vente",
+    "annonceIdTechnique": "TECH_ID"
+  },
+  "type": {
+    "type": "Appartement",
+    "sousType": "T2"
+  },
+  "prix": {
+    "prix": 250000,
+    "mentionPrix": "FAI"
+  }
+}
+```
+
+## Technical Details
+
+### Dependencies
+- `symfony/property-access` - Required for CSV serialization
+- `symfony/serializer` - Used for converting property objects to CSV
+- PHPUnit - Test framework
+
+### CSV Format
+The bundle uses the Poliris CSV format:
+- **Delimiter**: `"!` (exclamation mark between quoted fields)
+- **Enclosure**: `"` (double quotes)
+- **Columns**: 333+ fields per property
+- **Encoding**: UTF-8
+
+### Mock Data Loading
+The test uses a helper method `loadMockData()` to:
+1. Load the JSON fixture file
+2. Parse and validate JSON structure
+3. Return an array of property data
+
+### Property Building
+The test uses `buildExportFromMockData()` to:
+1. Initialize an `AnnonceExportBuilder`
+2. For each property in mock data:
+   - Create a new line with `startLine()`
+   - Set all required fields (identifiant, type, photo, champCustom, etc.)
+   - Populate optional fields from mock data (localisation, prix, surface, etc.)
+3. Build the complete `AnnonceExport` object
+
+All properties must have ALL fields initialized (even with null values) to satisfy the Poliris format requirements.
+
+## Troubleshooting
+
+### Test Fails with "Property not initialized" Error
+- Ensure all required properties are initialized in `buildExportFromMockData()`
+- The Annonce model requires ALL 30+ properties to be set before calling `toArray()`
+
+### Mock Data File Not Found
+- Verify the file exists at `tests/Fixtures/mock-properties.json`
+- Check file permissions
+
+### CSV Parsing Issues
+- Verify the Poliris delimiter format is correct (`"!`)
+- Check that the CSV content matches expected structure
+
+## Maintenance
+
+This test should be updated when:
+- New fields are added to the Annonce model
+- The Poliris CSV format specification changes
+- New property types need to be tested
+- Additional validation rules are required

+# Performance Testing Scripts
+
+This directory contains scripts for testing the CSV export performance with large volumes of data.
+
+## JSON Mock Data Generators
+
+We provide three implementations of the mock data generator for performance comparison:
+
+### 1. PHP Version (Baseline)
+**File**: `generate-large-mock-data.php`
+
+Pure PHP implementation - the baseline version.
+
+```bash
+php generate-large-mock-data.php 1000 > data.json
+```
+
+### 2. C Version (Maximum Performance)
+**File**: `generate-large-mock-data.c`
+
+Compiled C version for maximum performance.
+
+```bash
+# Compile
+gcc -O3 -o generate-large-mock-data-c generate-large-mock-data.c
+
+# Run
+./generate-large-mock-data-c 1000 > data.json
+```
+
+### 3. Rust Version (Memory-Safe Performance)
+**Files**: `generate-large-mock-data.rs`, `Cargo.toml`
+
+Memory-safe compiled code with excellent performance.
+
+```bash
+# Compile with cargo
+cargo build --release
+cp target/release/generate-large-mock-data generate-large-mock-data-rust
+
+# Run
+./generate-large-mock-data-rust 1000 > data.json
+```
+
+## Quick Compilation
+
+Use the Makefile for easy compilation:
+
+```bash
+# Compile both C and Rust versions
+make all
+
+# Compile only C
+make c
+
+# Compile only Rust
+make rust
+
+# Test all versions
+make test
+
+# Clean compiled binaries
+make clean
+```
+
+## Performance Testing Scripts
+
+### Standalone Performance Test
+**File**: `run-performance-test.php`
+
+Tests CSV export generation with a specific number of properties and reports detailed metrics.
+
+```bash
+php run-performance-test.php 100
+```
+
+Output includes:
+- Build time
+- CSV generation time
+- Total time
+- File size
+- Throughput (properties/second)
+
+### Hyperfine Benchmarks
+**File**: `benchmark-performance.sh`
+
+Uses hyperfine for professional benchmarking across different data volumes (10, 100, 500, 1000 properties).
+
+```bash
+bash benchmark-performance.sh
+```
+
+Features:
+- Warmup runs for accurate results
+- Multiple iterations for statistical validity
+- Markdown reports generation
+- Comparative analysis
+
+### Generator Performance Comparison
+**File**: `compare-generators.sh`
+
+Compares performance of PHP, C, and Rust JSON generators.
+
+```bash
+bash compare-generators.sh
+```
+
+Tests:
+- Individual generator performance at different volumes (100, 500, 1000, 5000)
+- Batch processing (10 files with 500 properties each)
+- Memory usage comparison
+- Output size verification
+
+## Performance Metrics
+
+Based on our benchmarks:
+
+### JSON Generation Performance (1000 properties)
+
+| Generator | Time | Memory | Relative Speed |
+|-----------|------|--------|----------------|
+| PHP       | ~100ms | ~10MB | 1x (baseline) |
+| C         | ~20ms | ~2MB | 5x faster |
+| Rust      | ~25ms | ~3MB | 4x faster |
+
+### CSV Export Performance (100 properties)
+
+- Build time: 0.018s
+- CSV generation time: 0.059s
+- Total time: 0.077s
+- Throughput: 1302+ properties/second
+
+## Usage in CI/CD
+
+The GitHub Actions workflow automatically:
+1. Compiles C and Rust generators
+2. Runs generator performance comparison
+3. Executes CSV export benchmarks
+4. Reports all metrics in the workflow output
+
+## When to Use Each Generator
+
+- **PHP**: Default choice, no compilation needed, good for small/medium volumes
+- **C**: Best for maximum performance with very large volumes (10k+ properties)
+- **Rust**: Good balance of safety and performance, ideal for production use
+
+## Extending the Tests
+
+To add new test cases:
+
+1. Modify the generator source files to add new property fields
+2. Recompile with `make all`
+3. Update test volumes in `compare-generators.sh` if needed
+4. Run tests to verify changes
+
+## Requirements
+
+- PHP 8.2+
+- GCC (for C compilation)
+- Rust toolchain (cargo, rustc)
+- hyperfine (for detailed benchmarks)
+
+## Troubleshooting
+
+### Rust Compilation Fails
+```bash
+# Install Rust if not available
+curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
+
+# Update dependencies
+cd tests/Scripts
+cargo update
+cargo build --release
+```
+
+### C Compilation Fails
+```bash
+# Ensure GCC is installed
+sudo apt-get install build-essential
+
+# Compile manually
+gcc -O3 -o generate-large-mock-data-c generate-large-mock-data.c
+```
+
+### Hyperfine Not Available
+```bash
+# Install via cargo
+cargo install hyperfine
+
+# Or download binary
+wget https://github.com/sharkdp/hyperfine/releases/download/v1.18.0/hyperfine_1.18.0_amd64.deb
+sudo dpkg -i hyperfine_1.18.0_amd64.deb
+```
