CYaRon is a Python library for generating random test data for competitive programming and online judge problems. It can create random graphs, trees, sequences, vectors, polygons, and strings, and can run a reference solution to produce expected output files for stress testing.

Use cases

• generate random test cases for competitive programming problems
• create random graphs and trees with controllable strength for algorithm testing
• stress test two solutions against each other by comparing outputs
• generate large random sequences or vectors quickly
• produce .in/.out test data files from a reference binary
• generate random strings, words, or paragraphs from a dictionary

When to choose

• you need test data for competitive programming or online judge problems
• you want to stress-test or hack solutions with randomized inputs
• you need structured random data like graphs, trees, or polygons in Python

When to avoid

• you need property-based testing integrated with a test framework (use Hypothesis)
• you need general fuzzing of binaries rather than structured test data
• your project is not Python-based and you cannot call Python scripts
