Step 4: Session 4 - Test Design

STEP GOAL:

To teach risk assessment and coverage planning using the TEA Test Design workflow in a 60-minute session.

MANDATORY EXECUTION RULES (READ FIRST):

Universal Rules:

• 🛑 NEVER generate content without user input
• 📖 CRITICAL: Read the complete step file before taking any action
• 🔄 CRITICAL: When loading next step with 'C', ensure entire file is read
• 📋 YOU ARE A FACILITATOR, not a content generator
• ✅ YOU MUST ALWAYS SPEAK OUTPUT In your Agent communication style with the config {communication_language}

Role Reinforcement:

• ✅ You are a Master Test Architect and Teaching Guide
• ✅ We engage in collaborative learning
• ✅ You bring expertise in TEA methodology

Step-Specific Rules:

• 🎯 Focus on Session 4 (Test Design)
• 💬 Teach workflow, provide examples

EXECUTION PROTOCOLS:

• 🎯 Load docs just-in-time
• 💾 Generate notes
• 📖 Update progress
• ⏭️ Return to hub

MANDATORY SEQUENCE

1. Welcome

"🧪 Session 4: Test Design (60 minutes)

Objective: Learn risk assessment and coverage planning

What you'll learn:

• Test Design workflow
• Risk/testability assessment
• Coverage planning with test levels
• Test priorities matrix

Let's plan some tests!"

2. Update Progress (Started)

Set session-04-test-design status: 'in-progress', started_date.

3. Teaching: Test Design Workflow

"### 📐 Test Design Workflow

Purpose: Plan tests BEFORE writing them (design before code).

Workflow Steps:

1. Load Context: Understand feature/system
2. Risk/Testability Assessment: Score probability × impact
3. Coverage Planning: Determine what to test and how
4. Generate Test Design Document: Blueprint for implementation

When to Use:

• New features (epic/system level)
• Major refactors
• Quality gate before development

Documentation: https://bmad-code-org.github.io/bmad-method-test-architecture-enterprise/how-to/workflows/run-test-design/"

4. Teaching: Risk/Testability Assessment

"### ⚖️ Risk & Testability Assessment

Risk Scoring:

• Probability: How likely is this to fail? (Low/Medium/High)
• Impact: What happens if it fails? (Low/Medium/High)
• Risk = Probability × Impact

Example: Login Feature

• Probability: High (complex, authentication)
• Impact: High (business critical)
• Risk: HIGH → P0 priority

Example: Tooltip Text

• Probability: Low (simple rendering)
• Impact: Low (aesthetic only)
• Risk: LOW → P3 priority

Testability:

• Can we test this easily?
• Are there dependencies blocking us?
• Do we need test infrastructure first?

{Role-adapted example}

Knowledge Fragments: probability-impact.md, test-priorities-matrix.md"

5. Teaching: Coverage Planning

"### 📋 Coverage Planning

Test Levels Framework:

Unit Tests: Isolated functions/classes

• Fast, focused
• No external dependencies
• Example: Pure functions, business logic

Integration Tests: Multiple components together

• Database, API interactions
• Example: Service layer with DB

E2E Tests: Full user workflows

• Browser automation
• Example: Complete checkout flow

Coverage Strategy:

• P0 features: Unit + Integration + E2E (high confidence)
• P1 features: Integration + E2E (good coverage)
• P2 features: E2E or Integration (basic coverage)
• P3 features: Manual or skip (low priority)

{Role-adapted example}

Knowledge Fragment: test-levels-framework.md

Documentation: https://bmad-code-org.github.io/bmad-method-test-architecture-enterprise/explanation/test-quality-standards/"

6. Teaching: Test Priorities Matrix

"### 📊 Test Priorities Matrix

P0-P3 Coverage Targets:

Priority	Unit	Integration	E2E	Manual
P0	✅	✅	✅	✅
P1	✅	✅	✅	-
P2	-	✅	-	✅
P3	-	-	-	✅

Goal: 100% P0, 80% P1, 50% P2, 20% P3

{Role-adapted example}

Knowledge Fragment: test-priorities-matrix.md"

7. Quiz (3 questions)

Q1: "What does the Test Design workflow help you do? A) Write tests faster B) Plan tests BEFORE writing them C) Run tests in parallel D) Debug test failures"

Correct: B

Q2: "How do you calculate risk? A) Probability + Impact B) Probability × Impact C) Probability - Impact D) Probability / Impact"

Correct: B

Q3: "For P0 features, which test levels should you use? A) Only E2E tests B) Only unit tests C) Unit + Integration + E2E (comprehensive) D) Manual testing only"

Correct: C

Calculate score, handle <70% retry.

8. Generate Session Notes

Create {sessionNotesFile} with Session 4 content, docs, fragments, quiz.

9. Update Progress (Completed)

Update session-04-test-design: completed, score, notes. Increment sessions_completed, update percentage. Append 'step-04-session-04' to stepsCompleted. Set next_recommended: 'session-05-atdd-automate'.

10. Complete Message

"🎉 Session 4 Complete! Score: {score}/100 You can now plan tests using risk assessment! Progress: {completion_percentage}%"

11. Menu

[A] Advanced Elicitation [P] Party Mode [C] Continue to Session Menu

Return to {nextStepFile}.
