# UN CLI Inception Test Suite Summary

## Created Test Files

All test files have been created in `/home/fox/git/unsandbox.com/cli/inception/tests/`:

| Language | Test File | Lines | Status |
|----------|-----------|-------|--------|
| Haskell | `test_un_hs.hs` | 163 | ✓ Ready |
| OCaml | `test_un_ml.ml` | 176 | ✓ Ready |
| Clojure | `test_un_clj.clj` | 153 | ✓ Ready |
| Scheme | `test_un_scm.scm` | 173 | ✓ Ready |
| Common Lisp | `test_un_lisp.lisp` | 178 | ✓ Ready |
| Erlang | `test_un_erl.erl` | 189 | ✓ Ready |
| Elixir | `test_un_ex.exs` | 191 | ✓ Ready |
| **Total** | **7 files** | **1,223 lines** | **All executable** |

## Test Coverage

Each test file provides comprehensive coverage of its corresponding UN CLI implementation:

### 1. Unit Tests - Extension Detection
- Tests 10+ file extension mappings
- Validates correct language identification
- Examples: `.hs` → `haskell`, `.py` → `python`, `.rs` → `rust`

### 2. Integration Tests - API Connectivity
- Creates temporary test file
- Executes code via UN CLI
- Verifies successful API communication
- Gracefully skips if no API key is set

### 3. Functional Tests - End-to-End
- Runs actual fibonacci test files (`fib.hs`, `fib.ml`, etc.)
- Validates complete workflow:
  - File reading
  - Language detection
  - API execution
  - Output formatting with ANSI colors
- Checks for expected output: `"fib(10) = 55"`

## Quick Start

```bash
# Navigate to inception directory
cd /home/fox/git/unsandbox.com/cli/inception/

# Set API key (required for integration/functional tests)
export UNSANDBOX_API_KEY="your_api_key_here"

# Run a single test
./tests/test_un_hs.hs

# Run all tests
for test in tests/test_un_{hs.hs,ml.ml,erl.erl,ex.exs,scm.scm}; do
    echo "Running $test..."
    ./$test
    echo ""
done
```

## Test Output Format

All test suites use consistent, color-coded output:

```
=== [Language] UN CLI Test Suite ===

✓ PASS - Extension detection
✓ PASS - API integration
✓ PASS - Fibonacci end-to-end test

✓ All tests passed (3/3)
```

## Exit Codes

- `0` - All tests passed
- `1` - One or more tests failed

## Key Features

1. **Self-Contained**: Each test is completely independent
2. **Executable**: All test files have shebang and execute permissions
3. **Graceful Degradation**: API tests skip if no key is set
4. **Detailed Errors**: Failed tests provide comprehensive error messages
5. **Consistent Interface**: All tests follow the same structure and output format
6. **Language-Idiomatic**: Tests written in native style for each language

## Dependencies

Tests require the same dependencies as their corresponding UN CLI implementations:

- **Haskell**: aeson, http-conduit, bytestring, text
- **OCaml**: cohttp-lwt-unix, yojson
- **Clojure**: clj-http, cheshire
- **Scheme**: guile-json (Guile Scheme)
- **Common Lisp**: dexador, jonathan (via Quicklisp)
- **Erlang**: Standard library (inets, ssl)
- **Elixir**: Standard library only

## Test Files Location

All test files are located relative to the UN CLI implementations:

```
cli/inception/
├── un.hs
├── un.ml
├── un.clj
├── un.scm
├── un.lisp
├── un.erl
├── un.ex
└── tests/
    ├── test_un_hs.hs      ← Test for un.hs
    ├── test_un_ml.ml      ← Test for un.ml
    ├── test_un_clj.clj    ← Test for un.clj
    ├── test_un_scm.scm    ← Test for un.scm
    ├── test_un_lisp.lisp  ← Test for un.lisp
    ├── test_un_erl.erl    ← Test for un.erl
    ├── test_un_ex.exs     ← Test for un.ex
    ├── README.md          ← Detailed documentation
    └── TESTING_SUMMARY.md ← This file
```

## Fibonacci Test Files

Tests reference the standard fibonacci examples in:

```
cli/test/
├── fib.hs
├── fib.ml
├── fib.clj
├── fib.scm
├── fib.lisp
├── fib.erl
└── fib.ex
```

Each fibonacci file outputs:
```
fib(0) = 0
fib(1) = 1
fib(2) = 1
...
fib(10) = 55
```

## Validation Strategy

Tests validate three critical aspects:

1. **Correctness**: Extension mappings match specification
2. **Connectivity**: CLI can reach and use the Unsandbox API
3. **Completeness**: Full execution cycle works end-to-end

## Next Steps

1. Run tests locally to verify all implementations work
2. Set up CI/CD integration (optional)
3. Add performance benchmarks (optional)
4. Extend tests for error handling scenarios (optional)

## Notes

- Tests are designed to run from the `cli/inception/` directory
- API tests gracefully skip when `UNSANDBOX_API_KEY` is not set
- All tests provide detailed failure messages for debugging
- Tests follow the same code style as their implementations
- Each test suite is ~150-190 lines of well-documented code
