Pict Test Designer

Design comprehensive test cases using PICT (Pairwise Independent Combinatorial Testing) for any piece of requirements or code. Analyzes inputs, generates PICT models with parameters, values, and constraints for valid scenarios using pairwise testing. Outputs the PICT model, markdown table of test cases, and expected results.

# PICT Test Designer

This skill enables systematic test case design using PICT (Pairwise Independent Combinatorial Testing). Given requirements or code, it analyzes the system to identify test parameters, generates a PICT model with appropriate constraints, executes the model to generate pairwise test cases, and formats the results with expected outputs.

## When to Use This Skill

Use this skill when:
- Designing test cases for a feature, function, or system with multiple input parameters
- Creating test suites for configurations with many combinations
- Needing comprehensive coverage with minimal test cases
- Analyzing requirements to identify test scenarios
- Working with code that has multiple conditional paths
- Building test matrices for API endpoints, web forms, or system configurations

## Workflow

Follow this process for test design:

### 1. Analyze Requirements or Code

From the user's requirements or code, identify:
- **Parameters**: Input variables, configuration options, environmental factors
- **Values**: Possible values for each parameter (using equivalence partitioning)
- **Constraints**: Business rules, technical limitations, dependencies between parameters
- **Expected Outcomes**: What should happen for different combinations

**Example Analysis:**

For a login function with requirements:
- Users can login with username/password
- Supports 2FA (on/off)
- Remembers login on trusted devices
- Rate limits after 3 failed attempts

Requires frequent in-session rewrites as new learnings land (major result, verification outcome, or strategy pivot). Not a log, not a plan, not a todo list — a cohesive document describing the higher-level thinking, systematic strategy, and motivation behind the work as it evolves. Updated end-to-end (rewritten, not appended) as understanding deepens.
