Rakulistest

Rakulistest is an open-source software project that provides a test framework and validation tools for list-processing operations, with emphasis on the semantics of lists in the Raku language. It offers a curated collection of test cases covering common list operations such as creation, concatenation, slicing, mapping, filtering, reduction, and sorting, along with utilities to compare expected and actual results.

The project aims to help developers verify correctness and interoperability when implementing list-related features in interpreters, compilers, and standard libraries across programming languages. It supports multiple test formats (for example YAML or JSON test suites) and can emit results in common formats used by continuous integration systems.

Rakulistest comprises a test runner, an assertion helper library, and a data-driven test format. It is designed to be language-agnostic, with adapters or backends for Raku and other languages, enabling tests to run in various environments.

Usage typically involves installing the Rakulistest package, writing test cases in the project’s test format, and invoking the test runner via a command-line interface or programmatic API. Results include pass/fail status and diagnostic messages to aid debugging.

Development history is community-driven and relatively modest in scope. The project has seen periodic updates and occasional contributions, with documentation maintained in its repository. It is used by some developers exploring list semantics and cross-language consistency.

Rakulistest is released under an open-source license; the exact terms depend on the version. The project is hosted publicly, with issue trackers and contribution guidelines for maintainers and users. See also Raku, list processing, test frameworks.
