# Bash Buddy Test Suite

Comprehensive testing framework for Bash Buddy with performance analysis and automated reporting.

## Overview

This test suite provides:
- **Automated testing** for all operating modes
- **Performance benchmarking** with statistical analysis
- **Interactive mode testing** using expect automation
- **Detailed reporting** in JSON, Markdown, and HTML formats
- **CI/CD integration** support

## Quick Start

### Run All Tests

```bash
cd tests/
./run-all-tests.sh
```

This will:
1. Run all non-interactive mode tests
2. Run interactive mode tests (if fzf available)
3. Generate performance benchmarks
4. Create comprehensive reports

### Run Specific Test Suites

```bash
# Test non-interactive modes only
./test-all-modes.sh

# Test interactive mode only
./test-interactive-mode.sh

# Analyze performance data
./analyze-performance.sh
```

- Average response time analysis

## Performance Benchmarks

### Targets

| Mode | Target | Typical |
|------|--------|---------|
| Database search | <100ms | ~50ms |
| Category browse | <100ms | ~30ms |
| Direct lookup | <200ms | ~100ms |
| Help display | <100ms | ~20ms |
| Interactive startup | <100ms | ~50ms |

## Continuous Integration

### GitHub Actions Example

```yaml
name: Test Bash Buddy

on: [push, pull_request]

jobs:
  test:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3

      - name: Install dependencies
        run: |
          sudo apt-get update
          sudo apt-get install -y jq fzf expect bc

      - name: Run tests
        run: |
          cd tests/
          ./run-all-tests.sh

      - name: Upload test results
        if: always()
        uses: actions/upload-artifact@v3
        with:
          name: test-results
          path: tests/reports/
```

### Gitea CI Example

```yaml
# .gitea/workflows/test.yml
name: Test Suite

on: [push, pull_request]

jobs:
  test:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout
        uses: actions/checkout@v3

      - name: Run tests
        run: |
          cd tests/
          ./run-all-tests.sh

      - name: Publish results
        if: always()
        run: |
          echo "Test results:"
          cat tests/reports/ci-report.txt
```

## Troubleshooting

### Tests Fail to Run

**Problem:** `bash: ./run-all-tests.sh: Permission denied`

**Solution:**
```bash
chmod +x tests/*.sh
```

### Interactive Tests Fail

**Problem:** Interactive tests skip or fail

**Reasons:**
- `fzf` not installed
- `expect` not installed
- Running in non-interactive environment

**Solution:**
```bash
# Install dependencies
sudo apt-get install -y fzf expect

# Check if interactive shell
echo $-  # Should contain 'i'
```

### AI Tests Skipped

**Problem:** AI mode tests are skipped

**Reasons:**
- Ollama not installed
- NL2SH model not available

**Solution:**
```bash
# Install Ollama
curl -fsSL https://ollama.ai/install.sh | sh

# Pull NL2SH model
ollama pull westenfelder/NL2SH
```

### Performance Benchmarks Too Slow

**Problem:** Tests take too long

**Solutions:**
- Reduce iteration count in benchmark calls
- Skip AI tests (they take 5-15s per query)
- Run specific test suites instead of all tests

**Edit iterations:**
```bash
# In test scripts, change:
run_benchmark "test name" "command" 10
# to:
run_benchmark "test name" "command" 3
```

### JSON Report Not Generated

**Problem:** `jq` not available

**Solution:**
```bash
sudo apt-get install -y jq
```

## Advanced Usage

### Custom Test Configuration

Create `tests/config.sh`:
```bash
# Test configuration
export TEST_TIMEOUT=30
export BENCHMARK_ITERATIONS=10
export SKIP_AI_TESTS=false
export SKIP_INTERACTIVE_TESTS=false
```

### Add Custom Tests

1. Create test file:
```bash
cd tests/
cat > test-custom.sh << 'EOF'
#!/bin/bash
source ./test-framework.sh

print_header
print_section "Custom Tests"

run_test_with_output_check \
    "My custom test" \
    "../bash-helper.sh ask 'my query'" \
    "expected output"

print_summary
EOF

chmod +x test-custom.sh
```

2. Run custom test:
```bash
./test-custom.sh
```

### Parallel Test Execution

```bash
# Run multiple test suites in parallel
./test-all-modes.sh &
./test-interactive-mode.sh &
wait

# Analyze results
./analyze-performance.sh
```

### Export Test Data

```bash
# Export to CSV
./run-all-tests.sh
cat performance/benchmarks.csv | column -t -s '|'

# Export to JSON
cat logs/test-report.json | jq '.'
```

## Test Framework API

### Core Functions

#### `run_test(name, command, expected_exit_code, timeout)`
Run test with basic exit code checking.

```bash
run_test "Test name" "command to run" 0 10
```

#### `run_test_with_output_check(name, command, expected_string, timeout)`
Run test and verify output contains expected string.

```bash
run_test_with_output_check \
    "Help test" \
    "./bash-helper.sh --help" \
    "Bash Buddy"
```

#### `run_benchmark(name, command, iterations)`
Run performance benchmark with statistics.

```bash
run_benchmark "Ask mode" "./bash-helper.sh ask 'test'" 10
```

#### `skip_test(name, reason)`
Skip test with reason.

```bash
skip_test "AI mode" "Ollama not available"
```

## Contributing Tests

### Adding New Test Cases

1. Identify test category (help, ask, explain, etc.)
2. Add test to appropriate section in `test-all-modes.sh`
3. Follow naming convention: `Mode - specific test case`
4. Include output validation
5. Document expected behavior

Example:
```bash
run_test_with_output_check \
    "Ask mode - new test case" \
    "$SCRIPT_PATH ask 'new query'" \
    "expected output keyword"
```

### Testing Checklist

Before submitting:
- [ ] Test passes locally
- [ ] Test has unique, descriptive name
- [ ] Output validation is specific
- [ ] Timeout is appropriate (10s default, 30s for AI)
- [ ] Test doesn't require manual interaction
- [ ] Dependencies are documented

## Maintenance

### Cleaning Test Data

```bash
# Remove all logs and reports
rm -rf tests/logs/* tests/performance/* tests/reports/*

# Run fresh test
./run-all-tests.sh
```

### Archiving Test Results

```bash
# Archive with timestamp
TIMESTAMP=$(date +%Y%m%d_%H%M%S)
tar -czf test-results-$TIMESTAMP.tar.gz \
    tests/logs tests/performance tests/reports

# Move to archive directory
mkdir -p archive/
mv test-results-$TIMESTAMP.tar.gz archive/
```

## Performance Tuning

### Speed Up Tests

1. **Skip slow tests**:
   ```bash
   # Comment out AI tests if not needed
   # Comment out benchmark sections
   ```

2. **Reduce iterations**:
   ```bash
   # Change from 10 to 3 iterations
   run_benchmark "test" "command" 3
   ```

3. **Parallel execution**:
   ```bash
   ./test-all-modes.sh & ./test-interactive-mode.sh & wait
   ```

### Optimize for CI/CD

```bash
# Fast CI mode
export TEST_TIMEOUT=5
export BENCHMARK_ITERATIONS=3
export SKIP_AI_TESTS=true
./run-all-tests.sh
```

## FAQ

**Q: How long do tests take?**
A: ~2-3 minutes for all tests (5-10 minutes with AI tests)

**Q: Can I run tests in parallel?**
A: Yes, but be careful with shared resources (log files, etc.)

**Q: Do I need root access?**
A: No, unless installing dependencies

**Q: Will tests modify my system?**
A: No, tests only read/execute bash-helper.sh

**Q: Can I run tests on macOS?**
A: Yes, with dependencies installed via Homebrew

**Q: How do I debug a failing test?**
A: Check `tests/logs/test_N_*.log` for detailed output
