This directory contains comprehensive tests for the Boxy container runtime.

Tests for port parsing functionality:

• Port mapping validation (8080:80, 8080:80/tcp, 8080:80/udp)
• Protocol validation (TCP/UDP)
• Port range validation (1-65535)
• Error handling for invalid formats
• Performance benchmarks

Tests for CNI (Container Network Interface) functionality:

• CNI configuration validation
• Port mapping conversion
• Network namespace path generation
• Context handling

Tests for port conflict detection:

• Available port detection
• Port-in-use detection (TCP/UDP)
• Multiple port validation
• Port availability checking

cd test
go test -v .

go test -v ./port_parse_test.go
go test -v ./cni_test.go
go test -v ./port_conflict_test.go

go test -bench=.

go test -cover .

The tests cover:

• ✅ Port parsing and validation
• ✅ Protocol handling (TCP/UDP)
• ✅ Error cases and edge conditions
• ✅ CNI configuration structure
• ✅ Network namespace utilities
• ✅ Port conflict detection
• ✅ Port availability checking
• ✅ Performance benchmarks

When adding new functionality to Boxy, please:

1. Add corresponding tests in this directory
2. Follow the existing naming conventions
3. Include both positive and negative test cases
4. Add benchmarks for performance-critical code
5. Update this README with new test descriptions

Test data and fixtures should be kept minimal and self-contained within the test functions to avoid external dependencies.
