Future Growth +The framework is ready for: +- More constraint tests (default values, knownValues, etc.) +- Raw identifier tests +- Lenient parsing tests +- Code generation tests (lexicon, TypeScript, Rust, Go) +- Real-world lexicon tests (bsky, place.stream, atproto) +- Bidirectional conversion tests + +## Next Steps + +### Immediate Additions +1. **namespace_imports/namespace_items** - `use com.example { foo, bar };` syntax +2. **namespace_exports/explicit_main** - `@main` annotation resolution +3. **namespace_exports/ambiguous_main** - Conflict detection without `@main` + +### Near-term Expansion +1. **Raw identifiers** - Keywords as field names, reserved names +2. **Lenient parsing** - Multiple errors, warning handling +3. **Esoteric cases** - Circular refs, empty unions, deep nesting + +### Long-term Vision +1. **Real-world lexicons** - Full bsky/place.stream test suites +2. **Code generation** - End-to-end codegen validation +3. **CLI integration** - Test `mlf check`, `mlf generate`, etc. +4. **Bidirectional** - Roundtrip MLF ↔ JSON conversion + +## Impact + +This test suite caught real issues during development: +- Namespace alias resolution bugs +- Import validation edge cases +- Constraint refinement logic + +It will continue to catch regressions as the language evolves, ensuring that features like namespace aliasing keep working correctly across future changes. + +## Usage + +```bash +# Run all integration tests +cargo test -p mlf-lang --test integration_test + +# See detailed output +cargo test -p mlf-lang --test integration_test -- --nocapture + +# Run after making changes +cargo test -p mlf-lang # Runs both unit and integration tests +``` + +Every MLF developer should run these tests before committing! diff --git a/mlf-lang/tests/integration_test.rs b/mlf-lang/tests/integration_test.rs new file mode 100644 index 0000000..51efba9 --- /dev/null +++ b/mlf-lang/tests/integration_test.rs @@ -0,0 +1,166 @@ +use mlf_integration_tests::test_utils;
