+
+Running Tests
+-------------
+
+``pyvat`` uses `pytest <https://pytest.org/>`_ for testing. To run the test suite:
+
+**Install test dependencies:**
+
+.. code-block:: bash
+
+    $ pip install pytest
+
+**Run all tests:**
+
+.. code-block:: bash
+
+    $ python -m pytest tests/ -v
+
+**Run specific test files:**
+
+.. code-block:: bash
+
+    # Test new countries implementation
+    $ python -m pytest tests/test_new_countries.py -v
+
+    # Test VAT charge calculations
+    $ python -m pytest tests/test_sale_vat_charge.py -v
+
+    # Test VAT number validators
+    $ python -m pytest tests/test_validators.py -v
+
+**Run with coverage:**
+
+.. code-block:: bash
+
+    $ pip install pytest-cov
+    $ python -m pytest tests/ --cov=pyvat --cov-report=html
+
+**Test Results:**
+
+The test suite includes:
+
+* **VAT Rules Tests**: Verify correct VAT rates for all supported countries
+* **Registry Tests**: Test B2B exemption logic for different countries
+* **VAT Charge Tests**: Ensure proper VAT calculation for cross-border sales
+* **Validator Tests**: Check VAT number format validation
+
+*Note: Some validator tests that call external VIES API are currently skipped and will be refactored with mocks.*
+
+
+Supported Countries
+-------------------
+
+**EU Countries**: All EU member states with full VIES integration
+
+**Special VAT Territories**:
+
+* **French DOM Territories** (RE, GP, MQ) - 8.5% VAT, outside EU VAT territory
+* **France & Monaco** (FR, MC) - Same VAT territory, 20% standard rate
+* **Non-EU Countries** (EG, CH, CA, NO) - Special VAT arrangements
+
+For detailed VAT rates, calculations, and examples for digital goods sold from France, see `FRANCE_VAT_RATES_DIGITAL_GOODS.md <docs/FRANCE_VAT_RATES_DIGITAL_GOODS.md>`_.

+
+## 1. France → Same VAT Territory
+
+**Countries**: France (FR), Monaco (MC)
+
+| Country | Buyer Type | VAT Action | VAT Rate | Charged In | Notes |
+|---------|------------|------------|----------|------------|-------|
+| **France** | B2C (Consumer) | Charge | **20%** | FR | Standard rate |
+| **France** | B2B (Business) | Charge | **20%** | FR | Same country |
+| **Monaco** | B2C (Consumer) | Charge | **20%** | MC | Same VAT territory |
+| **Monaco** | B2B (Business) | Charge | **20%** | MC | No reverse charge |
+
+**Key Points:**
+- France and Monaco are treated as the **same VAT territory**

+
+**Special Rates (France & Monaco):**

+- Standard digital services: 20%
+
+---
+

+| **Romania** | B2B (Business) | Reverse Charge | **0%** | RO | Business self-accounts |
+
+**Key Points:**

+- **B2B**: Reverse charge mechanism (0% on invoice, business pays VAT)
+- Standard EU cross-border rules apply
+
+**EU Country VAT Rates (Standard):**
+- Germany: 19%
+- Italy: 22%
+- Romania: 21%
+- Spain: 21%

+## 3. France → French DOM Territories
+
+**Countries**: Réunion (RE), Guadeloupe (GP), Martinique (MQ)
+
+| Country | Buyer Type | VAT Action | VAT Rate | Charged In | Notes |

+- No reverse charge for B2B
+- DOM rate is 8.5% (reduced rate compared to France's 20%)
+- Not affected by 2015 EU rule change
+
+**Important:**
+- VAT is charged at the **buyer's location** (DOM rate: 8.5%)
+- Different from France's standard 20% rate
+- Applies to all digital goods uniformly
+
+---
+
+## 4. France → Non-EU Countries (Special Cases)
+
+**Countries**: Egypt (EG), Switzerland (CH), Canada (CA), Norway (NO)
+
+| Country | Buyer Type | VAT Action | VAT Rate | Charged In | Notes |
+|---------|------------|------------|----------|------------|-------|
+| **Egypt** | B2C (Consumer) | Charge | **14%** | EG | Government mandate |
+| **Egypt** | B2B (Business) | No Charge | **0%** | - | B2B exempt |

+| **Canada** | B2C (Consumer) | No Charge | **0%** | - | No VAT on invoice |
+| **Canada** | B2B (Business) | No Charge | **0%** | - | B2B exempt |
+| **Norway** | B2C (Consumer) | Charge | **25%** | NO | Government mandate |
+| **Norway** | B2B (Business) | Charge | **25%** | NO | B2B NOT exempt |
+
+**Key Points:**
+- These countries have **special requirements** contrary to standard international tax law
+- Normally, EU sellers don't charge VAT to non-EU buyers
+- These countries have requested VAT be charged
+- **Egypt & Canada**: B2B transactions are exempt (0% VAT)
+- **Switzerland & Norway**: B2B transactions are NOT exempt (must charge VAT)
+
+**VAT Rates:**
+- Egypt: 14%
+- Switzerland: 8.1%
+- Canada: 0% (standard non-EU treatment)
+- Norway: 25%
+
+---
+
+## 5. France → Great Britain
+
+**Country**: Great Britain (GB) - **Post-Brexit (No longer in EU)**
+
+| Country | Buyer Type | VAT Action | VAT Rate | Charged In | Notes |
+|---------|------------|------------|----------|------------|-------|
+| **Great Britain** | B2C (Consumer) | Charge | **20%** | GB | UK VAT rate |
+| **Great Britain** | B2B (Business) | Reverse Charge | **0%** | GB | Business self-accounts |
+
+**Key Points:**
+- Great Britain is **NO LONGER part of the EU** (Brexit)
+- GB has been **removed from EU_COUNTRY_CODES**
+- **VAT rate: 20%** (UK standard rate - **same rate pre-Brexit and post-Brexit**)
+- **B2C**: Charge 20% UK VAT on invoice
+- **B2B**: Reverse charge mechanism applies (0% on invoice, buyer accounts for VAT)
+- Rules are **consistent for all dates** (no 2015 date dependency)
+
+**Post-Brexit Implementation:**
+- GB is treated as a non-EU country with special VAT rules
+- Similar to reverse charge mechanism used within EU for B2B
+- Different from standard non-EU treatment (which typically has no VAT charge)
+- **Note**: The 20% VAT rate remains unchanged from pre-Brexit to post-Brexit
+
+**Implementation:**
+- System only checks buyer type to apply correct rate
+- B2C always charges 20% on the invoice (same rate before and after Brexit)
+- B2B always uses 0% reverse charge
+- No date-dependent logic required
+- **VAT rate is 20% for all dates** (pre-Brexit and post-Brexit are the same)

+
+## Additional Information
+
+### 2015 EU VAT Rule Change
+
+On **January 1, 2015**, the EU changed VAT rules for B2C digital goods:
+- **Before 2015**: VAT charged at seller's country rate
+- **After 2015**: VAT charged at customer's country rate
+
+**Exception**: DOM territories are **NOT affected** by this change. They always use customer location rate.
+
+### Key Territories Explained
+
+1. **Same VAT Territory (FR, MC)**
+   - Treated as domestic transactions
+   - No reverse charge for B2B
+   - Always charge 20% VAT
+
+2. **DOM Territories (RE, GP, MQ)**
+   - Outside EU VAT territory
+   - Always charge VAT on invoice
+   - Use 8.5% DOM rate
+   - Not affected by 2015 change
+
+3. **Standard EU Countries**
+   - B2C: Charge at destination rate
+   - B2B: Reverse charge (0% on invoice)
+
+4. **Non-EU Special Cases**
+   - Egypt, Switzerland, Norway, Canada
+   - Each has unique requirements
+   - Some charge B2B, some don't
