+        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
