ISP-based test coverage is defined by creating a coverage model, setting targets, partitioning the input space, and sketching test cases to establish traceability from requirements. This approach ensures systematic input partitioning across API, data, and feature layers.

Traceability between requirements and test cases is maintained by linking testing elements like input partitions and test case sketches directly to motivation, API, data, and UX requirements. This cross-layer mapping ensures full coverage and identifies gaps.

Model test cases by defining coverage targets with input space partitions and describing environmental context variations. This allows you to systematically sketch test cases for API endpoints, data validation, and feature behavior across those varying contexts.

Yes, input space partitioning helps identify coverage gaps by systematically mapping input partitions against defined targets and cross-layer requirements. Describing environmental variations further highlights missing test cases to improve system resilience.

Yes, comprehensive test planning requires managing a multi-entity catalog including TestCoverageModel, TestCoverageTarget, InputSpacePartition, and TestCaseSketch. These entities work together to structure coverage criteria and manage test planning effectively.

Use input space partitioning when you need a structured approach to model and manage test coverage across multi-layered software systems. It is ideal for establishing clear traceability from requirements to test cases across API, data, and feature environments.
