Functional Test Case Generation and Coverage Analysis
Generate functional test cases and identify coverage gaps from game specs
What You Can Do
You can transform game design documents into organized functional test case matrices with clear objectives, preconditions, steps, expected results, and edge case identification. Claude analyzes your feature specifications to identify coverage gaps in existing test suites, revealing untested feature interactions and edge cases that informal testing might miss. This accelerates test planning while ensuring systematic coverage across complex game systems.
Features
Convert design specs into structured test cases with preconditions, steps, expected results, and acceptance criteria
Identify untested feature combinations and edge cases across game mechanics and systems
Discover how features interact (inventory + equipment, progression + multiplayer, etc.) and generate tests for those interactions
Systematically identify boundary conditions, invalid inputs, and state transition edge cases
Categorize test cases by feature area, priority level, and dependency chains for easy execution
Generate focused test suites for patched systems and feature updates
Produce standardized test case documentation for team consistency and new tester onboarding
Example Output
Example 1: Inventory System Test Cases
| Test ID | Feature | Objective | Precondition | Steps | Expected Result | Edge Case |
|---|---|---|---|---|---|---|
| INV-001 | Item Drop | Verify item removal from inventory | Player has sword in inventory | 1. Open inventory 2. Select sword 3. Click drop | Sword removed, appears on ground | Drop while full (10/10 items) |
| INV-002 | Stack Limit | Enforce max stack size | Player has 50 arrows | 1. Pick up 30 more arrows | Only 50 arrows (capped), 30 dropped | Stack overflow handling |
Example 2: Coverage Gap Report
Identified Gaps:
- No tests for simultaneous inventory drops + enemy knockback collision
- Missing tests for UI state transitions during network latency
- Equipment swap interactions with active ability cooldowns not covered
- No edge case testing for negative health state transitions
What's Included
- SKILL.md instruction file with overview, usage guidelines, and domain terminology:
- Test Case Template: Standardized spreadsheet/markdown format (ID, feature, objective, preconditions, steps, expected results, edge cases)
- Coverage Gap Analysis Framework: Checklist for identifying untested interactions, feature combinations, and boundary conditions
- Feature Dependency Matrix: Workflow for mapping how game systems interact and what integration tests are needed
- Edge Case Identification Checklist: Common functional testing blind spots (input validation, state transitions, overflow conditions, timing issues)
