   XML and JSON serialization and deserialization of GEDCOM X. For more information, see the [examples](https://github.com/FamilySearch/gedcomx-php/wiki/GEDCOM-X-Serialization). 
 
+## Testing
+
+The GedcomX PHP SDK includes a comprehensive test suite that runs on PHP 7.4, 8.0, 8.1, 8.2, and 8.3.
+
+### Running Tests
+
+```bash
+# Install dependencies
+composer install
+
+# Run the test suite
+vendor/bin/phpunit
+
+# Run tests with detailed output
+vendor/bin/phpunit --testdox
+
+# Generate coverage report (requires Xdebug or PCOV)
+vendor/bin/phpunit --coverage-html build/coverage
+```
+
+### Test Coverage
+
+The test suite includes:
+
+- ✅ Core GEDCOM X models (Person, Relationship, Fact, Name, Event, etc.)
+- ✅ FamilySearch extension models (ChildAndParentsRelationship, etc.)
+- ✅ XML and JSON serialization/deserialization
+- ✅ GEDCOMX file operations (.gedx archives)
+- ✅ Fixture validation (XML, JSON, GEDX)
+
+Coverage reports are automatically generated by CI and uploaded to [Coveralls](https://coveralls.io/github/FamilySearch/gedcomx-php?branch=master).
+
+### Continuous Integration
+
+Tests run automatically on every push and pull request via [GitHub Actions](https://github.com/FamilySearch/gedcomx-php/actions). All supported PHP versions are tested in parallel.
+
+For more details on testing, see [TESTING.md](TESTING.md).

+# Testing Guide
+
+## Overview
+
+This project uses PHPUnit 9.5+ for testing and supports PHP 7.4 through 8.3. All tests must pass on all supported PHP versions with zero deprecation warnings.
+
+## Supported PHP Versions
+
+- PHP 7.4
+- PHP 8.0
+- PHP 8.1
+- PHP 8.2
+- PHP 8.3
+
+## Running Tests Locally
+
+### Prerequisites
+
+```bash
+composer install
+```
+
+### Run All Tests
+
+```bash
+vendor/bin/phpunit
+```
+
+### Run Tests with Detailed Output
+
+```bash
+vendor/bin/phpunit --testdox
+```
+
+### Run Specific Test Suite
+
+```bash
+# Core model tests
+vendor/bin/phpunit tests/unit/ConclusionModelsTests.php
+
+# FamilySearch extension tests
+vendor/bin/phpunit tests/unit/FamilySearchExtensionsTests.php
+
+# Fixture validation tests
+vendor/bin/phpunit tests/unit/FixtureValidationTests.php
+```
+
+## Test Coverage
+
+### Running Coverage Reports Locally
+
+Coverage report generation requires Xdebug or PCOV extension:
+
+```bash
+# Generate HTML coverage report
+vendor/bin/phpunit --coverage-html build/coverage
+
+# Generate Clover XML for CI
+vendor/bin/phpunit --coverage-clover build/logs/clover.xml
+
+# Generate text summary
+vendor/bin/phpunit --coverage-text
+```
+
+### Coverage Baseline
+
+**Baseline established:** April 2026  
+**Test Count:** 64 tests, 142 assertions  
+**Status:** ✅ 100% passing on PHP 7.4-8.3
+
+The project maintains comprehensive test coverage for:
+
+- ✅ **Core GEDCOM X models** (23 tests) - Person, Relationship, Fact, Name, Gender, Event, Document, PlaceDescription, etc.
+- ✅ **Source models** (8 tests) - SourceDescription, SourceCitation, SourceReference, CitationField
+- ✅ **Agent models** (7 tests) - Agent, Address, OnlineAccount
+- ✅ **FamilySearch extensions** (16 tests) - ChildAndParentsRelationship, Discussion, Comment, User, etc.
+- ✅ **File operations** (4 tests) - XML/JSON serialization, GEDCOMX archive operations
+- ✅ **Fixture validation** (6 tests) - XML/JSON well-formedness, round-trip testing
+
+**Detailed coverage breakdown:** See [TEST_COVERAGE.md](TEST_COVERAGE.md) for a complete list of tested models.
+
+**Where to find coverage reports:**
+
+- GitHub Actions CI: Coverage artifacts are uploaded on every push to `master` and for all pull requests
+- Coveralls.io: [![Coverage Status](https://coveralls.io/repos/FamilySearch/gedcomx-php/badge.svg?branch=master&service=github)](https://coveralls.io/github/FamilySearch/gedcomx-php?branch=master)
+- CI runs coverage on PHP 8.3 only to optimize build time
+
+## Continuous Integration
+
+Tests run automatically via GitHub Actions on:
+
+- Every push to `master`
+- Every pull request targeting `master`
+- All supported PHP versions in parallel
+
+### CI Workflow
+
+The CI pipeline (`.github/workflows/ci.yml`) runs:
+
+1. `composer validate --strict` - Validates composer.json and composer.lock
+2. `composer install --prefer-dist --no-progress` - Installs dependencies
+3. `vendor/bin/phpunit` - Runs the full test suite
+4. Coverage generation (PHP 8.3 only) and upload to Coveralls

+- README badge shows current master status
+- PR checks must pass before merging

+└── tmp/                       # Temporary files (gitignored)
+```
+
+### Test Fixtures
+
+Test fixtures are located in `tests/files/`:
+
+- **XML fixtures**: GEDCOM X XML documents
+- **JSON fixtures**: GEDCOM X JSON documents  
+- **GEDX files**: ZIP-based GEDCOM X archives
+
+All fixtures are validated for well-formedness as part of the test suite.
+
+## Writing Tests
+
+### Test Naming Convention
+
+- Test files must end with `Tests.php` (plural)
+- Test methods must start with `test`
+- Use descriptive names: `testPersonWithMultipleFacts()`
+
+### Test Coverage Requirements
+
+New features should include tests for:
+
+1. **Construction**: Object can be created with various inputs
+2. **Getters/Setters**: All public properties are accessible
+3. **JSON Serialization**: Model serializes to valid JSON
+4. **JSON Deserialization**: JSON deserializes to correct model
+5. **Round-trip**: Serialize → Deserialize → Serialize produces same result
+6. **XML Serialization**: Model serializes to valid XML (where applicable)
+7. **XML Deserialization**: XML deserializes to correct model (where applicable)
+
+### Example Test
+
+```php
+public function testPersonWithName()
+{
+    $person = new Person();
+
+    $nameForm = new NameForm();
+    $nameForm->setFullText('John Smith');
+
+    $name = new Name();
+    $name->setNameForms([$nameForm]);
+
+    $person->setNames([$name]);
+
+    $this->assertCount(1, $person->getNames());
+    $this->assertEquals('John Smith', $person->getNames()[0]->getNameForms()[0]->getFullText());
+
+    // Test JSON round-trip
+    $json = $person->toJson();
+    $person2 = new Person(json_decode($json, true));
+    $this->assertEquals('John Smith', $person2->getNames()[0]->getNameForms()[0]->getFullText());
+}
+```
+
+## Strict Testing Mode
+
+The test suite runs in strict mode to ensure code quality:
+
+- **failOnWarning="true"**: PHPUnit fails on any warning
+- **Deprecation handling**: `tests/bootstrap.php` converts E_DEPRECATED to exceptions
+- **No suppressed errors**: All errors must be fixed, not suppressed
+
+This ensures that:
+- Code works correctly on all PHP versions
+- No deprecation warnings on PHP 8.x
+- Issues are caught early in development
+
+## Troubleshooting
+
+### "No code coverage driver available"
+
+Install Xdebug or PCOV:
+
+```bash
+# macOS with Homebrew
+pecl install xdebug
+
+# Ubuntu/Debian
+sudo apt-get install php-xdebug
+```
+
+### Tests fail with deprecation warnings
+
+1. Check which PHP version introduced the deprecation
+2. Fix the underlying issue (don't suppress the warning)
+3. Verify tests pass on all supported PHP versions
+
+### "Class not found" errors
+
+```bash
+composer dump-autoload
+```
+
+### Test fixtures not found
+
+Ensure `tests/files/` directory exists with fixture files. Check paths in test assertions.
+
+## Best Practices
+
+1. **Run tests before committing**: `vendor/bin/phpunit`
+2. **Test on multiple PHP versions** if making significant changes
+3. **Keep tests fast**: Current suite runs in < 1 second
+4. **Don't commit generated files**: `.phpunit.result.cache` and `build/` are gitignored
+5. **Update this document** when adding new test infrastructure
