property-based-testing

Property-based testing validates software by defining input-output invariants rather than specific examples. Use it when developing algorithms or functions requiring rigorous validation against a wide range of generated inputs to ensure code reliability.

Write property-based tests by defining clear input-output invariants for your function and selecting appropriate fast-check arbitraries as data generators. This guides the generation of diverse input spaces to thoroughly validate algorithm correctness and test coverage.

Define testable properties for sorting algorithms by stating invariants like "the output array is always sorted" and "contains the same elements as the input." This ensures correctness by verifying input-output relationships across generated inputs.

Yes, property-based testing works for validating functions with diverse input spaces by guiding the selection of effective data arbitraries. This generates a wide range of inputs to rigorously validate algorithms and improve code quality.

Property-based testing requires defining clear input-output invariants and selecting appropriate data generators, which can be more complex than writing specific example-based tests. It focuses on broad code reliability rather than targeting specific known edge cases.

Review existing property-based tests by applying testing principles to evaluate their quality and focus. Check if they define clear invariants and use appropriate data generators to ensure thorough test coverage and code reliability.
