Comprehensive Test Infrastructure

[behrangsa]

Summary

Implement a comprehensive testing framework with unit tests, integration tests, and cross-platform validation.

Acceptance Criteria

• Unit tests for all core functions
• Integration tests using temporary Git repositories
• Cross-platform test execution
• Test helper utilities for repository setup
• Performance benchmarking tests
• Regression test suite
• Automated test execution in CI/CD
• Code coverage reporting (>90%)

Priority: High

Effort: 8 story points
Phase: Elaboration

Source

Reverse engineered from husky/test/ directory structure and test patterns

Dependencies

• Depends on: Core Hook Installation System #1 (Core Installation), Command Line Interface #2 (CLI), Hook Execution Runtime #3 (Hook Runtime)
• Blocks: CI/CD Pipeline with GitHub Actions #11 (CI/CD Pipeline)
• Relates to: Robust Error Handling #6 (Error Handling), Cross-Platform Compatibility #7 (Cross-Platform Compatibility)

Testing infrastructure requires a working implementation to test. It must be in place before CI/CD can be set up.

🚨 Node.js/NPM Testing Baggage Detected @behrangsa

After reviewing issue #5, I found Node.js-specific testing assumptions that need updating for our Rust ecosystem:

❌ Node.js Testing Baggage:

1. "npm pack" based testing approach

From Husky source: Tests used npm pack to create husky.tgz and npm install ../husky.tgz
Problem: This is Node.js package manager specific
Solution: Use Rust ecosystem testing - cargo build, local binaries, integration tests

2. package.json manipulation in tests

From Husky tests: Modified package.json with \"prepare\": \"husky\" scripts
Problem: Not relevant for Rust-based samoid.toml
Solution: Test samoid.toml creation and modification instead

✅ Updated Requirements Should Be:

• Unit tests for all core functions (using cargo test)
• Integration tests using temporary Git repositories
• Cross-platform test execution (cargo test on Windows/macOS/Linux)
• Test helper utilities for repository setup
• Performance benchmarking tests (cargo bench)
• Regression test suite
• Automated test execution in CI/CD (GitHub Actions with cargo test)
• Code coverage reporting with cargo tarpaulin (>90%)

✅ Rust-Native Testing Approach:

Instead of npm pack/install, use:

# Build samoid binary for testing
cargo build --bin samoid

# Create test repos and install samoid from local binary
./target/debug/samoid init

# Test samoid.toml generation and hook installation

Test structure should follow Rust conventions:

• Unit tests in src/ files with #[cfg(test)]
• Integration tests in tests/ directory
• Helper utilities in tests/common/mod.rs

Should I update this issue to use Rust ecosystem testing patterns?
