# How to Run Test Design
Use TEA's `*test-design` workflow to create comprehensive test plans with risk assessment and coverage strategies.
---
## When to Use This
**System-level (Phase 3):**
- After architecture is complete
- Before implementation-readiness gate
- To validate architecture testability
**Epic-level (Phase 4):**
- At the start of each epic
- Before implementing stories in the epic
- To identify epic-specific testing needs
---
## Prerequisites
- BMad Method installed
- TEA agent available
- For system-level: Architecture document complete
- For epic-level: Epic defined with stories
---
## Steps
### 1. Load the TEA Agent
Start a fresh chat and load the TEA (Test Architect) agent.
### 2. Run the Test Design Workflow
```
*test-design
```
### 3. Specify the Mode
TEA will ask if you want:
- **System-level** - For architecture testability review (Phase 3)
- **Epic-level** - For epic-specific test planning (Phase 4)
### 4. Provide Context
For system-level:
- Point to your architecture document
- Reference any ADRs (Architecture Decision Records)
For epic-level:
- Specify which epic you're planning
- Reference the epic file with stories
### 5. Review the Output
TEA generates a comprehensive test design document.

## What You Get
### System-Level Output (`test-design-system.md`)
- Testability review of architecture
- ADR → test mapping
- Architecturally Significant Requirements (ASRs)
- Environment needs
- Test infrastructure recommendations
### Epic-Level Output (`test-design-epic-N.md`)
- Risk assessment for the epic
- Test priorities
- Coverage plan
- Regression hotspots (for brownfield)
- Integration risks
- Mitigation strategies

## Test Design for Different Tracks
### Greenfield - BMad Method
| Stage | Test Design Focus |
|-------|-------------------|
| Phase 3 | System-level testability review |
| Phase 4 | Per-epic risk assessment and test plan |
### Brownfield - BMad Method/Enterprise
| Stage | Test Design Focus |
|-------|-------------------|
| Phase 3 | System-level + existing test baseline |
| Phase 4 | Regression hotspots, integration risks |
### Enterprise
| Stage | Test Design Focus |
|-------|-------------------|
| Phase 3 | Compliance-aware testability |
| Phase 4 | Security/performance/compliance focus |
---
## Tips
- Run system-level test-design right after architecture
- Run epic-level test-design at the start of each epic
- Update test design if ADRs change
- Use the output to guide `*atdd` and `*automate` workflows
