# GRASP-01 Test Plan

**Date:** November 5, 2025  
**Status:** Planning Phase  
**Scope:** Complete test coverage for GRASP-01 Core Service Requirements

---

## Overview

This document outlines all tests needed to validate GRASP-01 compliance. Each test maps directly to requirements in `../grasp/01.md`.

**Test Strategy:**
1. Build tests against ngit-relay reference implementation FIRST
2. Each requirement = one or more test functions
3. All tests reference specific spec line numbers
4. Tests organized by spec sections

---

## Test Organization

```
grasp-audit/src/specs/
├── mod.rs                          # Export all test modules
├── nip01_smoke.rs                  # ✅ DONE - Basic relay functionality
├── grasp01_nostr_relay.rs          # NEW - Nostr relay requirements
├── grasp01_git_http.rs             # NEW - Git Smart HTTP requirements
└── grasp01_cors.rs                 # NEW - CORS requirements
```

---

## 1. NIP-01 Smoke Tests (✅ COMPLETE)

**File:** `grasp-audit/src/specs/nip01_smoke.rs`

**Status:** Already implemented and working

**Coverage:**
- ✅ WebSocket connection
- ✅ Send/receive events
- ✅ Subscriptions (REQ/CLOSE)
- ✅ Event validation (signatures, IDs)

**Note:** These are smoke tests only. We don't comprehensively test NIP-01 since rust-nostr already has 1000+ tests.

---

## 2. GRASP-01 Nostr Relay Tests (🔜 TO DO)

**File:** `grasp-audit/src/specs/grasp01_nostr_relay.rs`

- Verify relay can reject for reasons like:
  - Pre-payment required
  - Quota exceeded
  - WoT filtering
  - Whitelist
  - SPAM prevention
- Document in test that this is implementation-specific

```rust
/// Test: MAY reject/delete for SPAM prevention
/// Spec: Line 10
/// Requirement: Generic SPAM prevention allowed
async fn test_spam_prevention_allowed()
```

**Test Details:**
- Document that relay may reject/delete for SPAM
- This is permissive, not mandatory
- Test should document the policy, not enforce specific behavior

---

## Implementation Priority

### Phase 1: Core Nostr Relay Tests (Complete these first)
1. ✅ NIP-01 smoke tests (DONE)
2. Repository announcement acceptance/rejection
3. Repository state announcement acceptance
4. NIP-11 relay information document
5. Related event acceptance (issues, patches, PRs)

### Phase 2: Git Smart HTTP Tests
1. Repository serving at correct paths
2. Unauthenticated clone/fetch
3. Push authorization and maintainer sets
4. HEAD management
5. Git protocol features (SHA1 capabilities)

### Phase 3: Advanced Git Features
1. Pull request refs (refs/nostr/<event-id>)
2. PR ref lifecycle (creation, validation, deletion)
3. Web interface (optional)

### Phase 4: CORS Tests
1. CORS headers on all endpoints
2. OPTIONS request handling
3. Preflight requests
4. Error response CORS

---

## Test Execution Plan

### Against ngit-relay Reference Implementation

```bash
# 1. Start ngit-relay
cd ../ngit-relay
docker-compose up -d

# 2. Run tests
cd ../ngit-grasp/grasp-audit
cargo test --lib  # Unit tests

# Run integration tests by category
cargo test --test grasp01_nostr_relay
cargo test --test grasp01_git_http
cargo test --test grasp01_cors

# 3. Run full audit
cargo run -- --url ws://localhost:8081
```

### Test Data Requirements

For comprehensive testing, we need:
- Multiple test keypairs (maintainers, contributors, non-maintainers)
- Sample git repositories with known commit history
- Valid NIP-34 event templates
- Test data for edge cases

---

## Success Criteria

- [ ] All GRASP-01 requirements have corresponding tests
- [ ] All tests reference specific spec line numbers
- [ ] All tests pass against ngit-relay reference implementation
- [ ] Tests are organized logically by spec sections
- [ ] Clear test output shows what requirement is being tested
- [ ] Tests can be run individually or as full suite
- [ ] Documentation explains what each test validates

---

## Notes

### Spec Line Number References

When implementing tests, use this format:

```rust
/// Test: <Short description>
/// Spec: Lines X-Y of ../grasp/01.md
/// Requirement: <Exact quote or paraphrase from spec>
async fn test_name() {
    // Implementation
}
```

### Test Naming Convention

- `test_accept_*` - Tests that verify acceptance of valid input
- `test_reject_*` - Tests that verify rejection of invalid input
- `test_serve_*` - Tests that verify correct serving of data
- `test_cors_*` - Tests for CORS functionality
- `test_nip11_*` - Tests for NIP-11 relay information

### Edge Cases to Consider

1. **Concurrent updates** - Multiple maintainers pushing simultaneously
2. **Large repositories** - Performance with large git data
3. **Invalid git data** - Corrupted pack files, invalid refs
4. **Event ordering** - State announcement before repo announcement
5. **Deleted events** - What happens when announcement is deleted?
6. **Network failures** - Partial push, interrupted clone
7. **Recursive maintainers** - Deep maintainer chains, circular references

---

**Next Steps:**
1. Implement Phase 1 tests (Nostr relay)
2. Run against ngit-relay to validate
3. Fix any failing tests
4. Move to Phase 2 (Git HTTP)
5. Iterate until all tests pass
