# PHPUnit - Compatibility Research
|
|
|
|
## Latest Version & Changes
|
|
**Current Latest**: PHPUnit 12.3.10 (September 11, 2025)
|
|
**PHP 8.0 Compatibility**: Requires PHPUnit 9.3.0+ (NOT latest version)
|
|
|
|
### Version Matrix

|
|
- **PHPUnit 11.x**: Requires PHP ≥8.2
|
|
- **PHPUnit 10.x**: Requires PHP ≥8.1
|
|
- **PHPUnit 9.3.0+**: Supports PHP 8.0
|
|
|
|
## Known Issues & Problems
|
|
- **PHP 8.0 + Latest PHPUnit**: INCOMPATIBLE
|
|
- **Union Types**: PHPUnit 8.5 doesn't support PHP 8 union types
|
|
- **Feature Limitations**: Older PHPUnit versions lack modern features
|
|
- **Security Support**: PHP 8.0 EOL impacts testing security
|
|
|

## Best Practices & Recommendations
|
|
### For PHP 8.0 Projects
|
|
- **Use**: PHPUnit 9.3.0+ (not latest 12.x)
|

|
|
- **Migration Path**: Upgrade to PHP 8.1+ → PHPUnit 10+
|
|
|
|
### Optimal Setup (2025)
|
|
- **PHP Version**: 8.1+ (minimum) or 8.4 (recommended)
|
|
- **PHPUnit Version**: Latest compatible (10+ or 12.x)
|
|
- **Testing Strategy**: Full feature support with modern PHP
|
|
|
|
### Production Testing
|
|
- **Coverage**: 90%+ recommended with compatible PHPUnit
|
|
- **Integration**: Full API endpoint testing
|
|
- **Performance**: Load testing capabilities
