# 100% Test Coverage Implementation Schedule

## Week 1: Critical Path Testing (Target: 25% → 40% coverage)

### Day 1-2: Test Infrastructure
Create essential test utilities and fix existing test issues.

**Files to create:**
```bash
tests/helpers/
├── test-factory.ts           # Entity & relationship factories
├── test-assertions.ts        # Custom matchers
├── test-mocks.ts             # Mock implementations
└── coverage-reporter.ts      # Coverage tracking
```

**Actions:**
1. Fix all TypeScript errors in existing tests
2. Create factory functions for all entity types
3. Create mock storage adapters
4. Setup coverage reporting

### Day 3-5: Core CRUD Operations
Complete test coverage for basic operations.

**Test files to create/update:**

```

**Specific scenarios to test:**
```typescript

## Daily Execution Plan

### Daily Routine:
```bash
# Morning: Write tests
npm run test:watch -- path/to/current.test.ts

# Afternoon: Check coverage
npm run test:coverage -- path/to/module

# Evening: Verify progress
npm run test:coverage:report
```

### Coverage Tracking:
```typescript
// tests/helpers/coverage-tracker.ts
export class CoverageTracker {
  static async report() {
    const coverage = await getCoverage()
    console.log(`
      Current Coverage: ${coverage.statements}%
      Target Coverage: 100%
      Remaining Lines: ${coverage.uncoveredLines}
      Files Complete: ${coverage.filesAt100Percent}
      Files Remaining: ${coverage.filesBelow100Percent}
    `)
  }
}
```

# scripts/generate-tests.sh

for file in src/**/*.ts; do
  test_file="tests/unit/${file#src/}"
  test_file="${test_file%.ts}.test.ts"
  
  if [ ! -f "$test_file" ]; then
    mkdir -p "$(dirname "$test_file")"
    echo "Creating test for $file -> $test_file"
    npm run generate:test -- "$file" > "$test_file"
  fi
done
```

### Coverage monitoring:
```bash
#!/bin/bash
# scripts/monitor-coverage.sh

while true; do
  clear
  npm run test:coverage:summary
  echo "---"
  echo "Uncovered files:"
  npm run test:coverage:uncovered
  sleep 60
done
```

## Success Metrics

### Daily Targets:

- Day 6-10: +3% coverage per day
- Day 11-20: +2% coverage per day
- Day 21-25: +1.5% coverage per day
- Day 26-30: +1% coverage per day

### Weekly Milestones:
- Week 1: Core APIs tested (40% coverage)
- Week 2: Relationships & Search (55% coverage)
- Week 3: Storage complete (70% coverage)
- Week 4: Augmentations done (85% coverage)
- Week 5: Neural/AI tested (92% coverage)
- Week 6: 100% coverage achieved

## Immediate Next Steps

1. **Fix existing test compilation errors** (2 hours)
2. **Create test factory utilities** (2 hours)
3. **Test `brain.add()` completely** (2 hours)
4. **Test `brain.relate()` completely** (2 hours)
5. **Run coverage report and verify progress** (30 min)

## Commands to Run Now:

```bash
# Fix TypeScript errors in tests
npm run type-check

# Create test infrastructure
mkdir -p tests/helpers
touch tests/helpers/test-factory.ts
touch tests/helpers/test-assertions.ts

# Start with core CRUD tests
npm run test:watch -- tests/unit/brainy/add.test.ts

# Monitor coverage
npm run test:coverage:watch
```

This schedule provides a realistic, day-by-day plan to achieve 100% coverage in 6 weeks (30 working days). The key is systematic execution and daily progress tracking.
