About:
PICT is a command-line tool that generates test cases using pairwise (2-way) combinatorial testing methodology. It significantly reduces the number of tests needed while maintaining high defect detection rates by covering all unique pairs of input parameters. This helps QA engineers and developers efficiently test complex systems with multiple input combinations.

Key Features:

Generates minimal set of test cases using pairwise combinatorial algorithms
Supports weighted combinations, constraints, and negative testing
Fast execution with efficient memory usage for large parameter sets
Simple model file syntax for defining test parameters and relationships

Use Cases:

Software testing: Generating comprehensive test cases for application input validation
Hardware compatibility testing: Testing combinations of drivers, OS versions, and hardware configurations
Configuration testing: Validating software settings across different environment combinations
API testing: Testing parameter combinations for REST endpoints and function calls

Alternatives:

AllPairs – Java-based alternative with similar functionality but less active development
ACTS (Combinatorial Testing Tool) – NIST-developed tool with GUI interface and more advanced features but steeper learning curve
