Plan Tests

Create test scenarios from a design doc. This runs BEFORE implementation - think about testing independently from how the feature will be built.

Why Independence Matters

Testing that follows implementation just validates what was built. Testing that precedes implementation catches:

•Edge cases the implementation would miss
•Missing requirements in the design
•Assumptions that need validation

Input

Design doc path from user.

Process

1. Read the Design Doc

Understand the business requirements and user flows. Focus on WHAT the system should do, not HOW.

2. Read Testing Standards (if available)

Check for existing testing strategy docs. Common locations:

•docs/standards/TESTING_STRATEGY.md
•docs/testing/
•Project README

3. Check Existing Examples

Scan for existing test scenario files to match structure and depth.

4. Consolidation Pass (Critical)

BEFORE writing scenarios, run this checklist:

• What test cases are duplicates? Remove.
• What test cases share setup AND action? Combine into one test with multiple assertions.
• Can I verify side effects in the same test that causes them? Do it.
• Each remaining test answers: "What unique scenario am I testing?"

Goal: Minimum tests for maximum confidence.

5. Write Scenarios

Focus on business logic, skip:

•Auth/authorization (system concern)
•Input validation boilerplate
•Framework mechanics

For each scenario, include:

•Setup (GIVEN): What data/state exists
•Action (WHEN): What operation triggers
•Assertions (THEN): What to verify (DB state, API calls, side effects)

Use describe blocks to group related scenarios.

Output

Write to: docs/for_ai/test_scenarios_for_ai/[feature-name]_test_scenarios.md

Or your project's equivalent location.

Structure:

markdown

# [Feature] Test Scenarios

## Overview

Brief context on what's being tested and key business rules.

## Test Suite: [Logical Grouping]

### Test: "should [behavior] when [condition]"

In plain English.
**GIVEN:** Setup details
**WHEN:** Action (usually API call)
**THEN:** Assertions

Final Step: QA Review

After writing scenarios, spawn the qa-reviewer agent to review for coverage gaps. Pass it:

•The scenarios doc you just wrote
•The design doc path

Address critical/important gaps before considering scenarios complete.
