## [Unreleased]



## [0.1.0] - 2026-01-19



### Added

- Initial release of PropWise

- AST-based analysis for identifying property-based testing candidates

- Purity analysis to detect functions without side effects

- Pattern detection for seven types of testable patterns:

  - Collection operations (Enum, Stream, comprehensions)

  - Data transformations (pipelines, struct/map manipulation)

  - Validation functions (predicates, boolean checks)

  - Algebraic structures (merge, concat, compose operations)

  - Encoder/decoder functions

  - Parser functions

  - Numeric algorithms

- Inverse function pair detection (encode/decode, serialize/deserialize, etc.)

- Concrete property-based test generation using stream_data

- Testability scoring system with configurable threshold

- Command-line interface via escript

- Mix task integration (`mix propwise`)

- JSON and text output formats

- Configuration file support (`.propwise.exs`)

- Comprehensive documentation and scoring guide
