# ๐งช TOML Parser Test Suite & Quality Assurance
`oak-toml` features a comprehensive test suite to ensure stability across various TOML features and edge cases.
## ๐ Test Coverage
Our test suite is organized into several core levels to ensure full language compliance and structural accuracy:
### 1. Lexer Tests
Validates the correct identification of all TOML tokens, including keys (simple, quoted, dotted), strings (basic, multiline, literal), numbers, and dates.
- **Directory**: `tests/lexer/`
- **Mechanism**: Snapshot-based verification comparing against expected token streams.
### 2. Parser Tests
Verifies the structural correctness of the Abstract Syntax Tree (AST), covering:
- **Tables**: Standard tables, nested tables, inline tables, and arrays of tables.
- **Key-Value Pairs**: Correct parsing of complex key structures and all TOML value types.
- **Data Types**: Native support for integers, floats, booleans, and RFC3339 date-times.
### 3. Error Recovery
Specifically tests the parser's robustness when facing malformed TOML (e.g., re-defined keys, unclosed strings, or invalid table headers), ensuring it can continue parsing subsequent sections and produce useful diagnostics.
### 4. Specification Compliance
Validation against the TOML specification to ensure that the parser correctly handles standard-specific rules and edge cases.
## ๐ Running Tests
You can run the full test suite using:
```bash
# Run standard Rust tests using cargo
cargo test -p oak-toml
# Or use the project-wide task runner
wee test
```
## ๐ Contributing Tests
If you discover a TOML edge case or a valid configuration snippet that doesn't parse correctly, we welcome contributions! Please add a new `.toml` file to the `tests/` directory representing the case and submit a PR.
