Test Cases

Takes your PRD or requirements doc and generates structured test cases with proper coverage mapping. You get functional tests, edge cases, error handling, and state transitions organized into a markdown file with a traceability matrix. Each test case includes preconditions, steps, expected results, and links back to specific requirements. The workflow is thorough: it reads your PRD, extracts scenarios, validates coverage gaps, then outputs everything to tests/ with TC-F, TC-E, TC-ERR, and TC-ST prefixes. Best for when you need QA documentation that maps cleanly to requirements rather than just ad hoc test ideas. The requirement-driven approach means you won't ship features without corresponding test coverage.

Test Cases Generator

This skill generates comprehensive, requirement-driven test cases from PRD documents or user requirements.

Purpose

Transform product requirements into structured test cases that ensure complete coverage of functionality, edge cases, error scenarios, and state transitions. The skill follows a pragmatic testing philosophy: test what matters, ensure every requirement has corresponding test coverage, and maintain test quality over quantity.
