TEA Configuration Reference

Complete reference for all TEA (Test Architect) configuration options.

Configuration File Locations

User Configuration (Installer-Generated)

Location: _bmad/bmm/config.yaml

Purpose: Project-specific configuration values for your repository

Created By: BMad installer

Status: Typically gitignored (user-specific values)

Usage: Edit this file to change TEA behavior in your project

Example:

# _bmad/bmm/config.yaml
project_name: my-awesome-app
user_skill_level: intermediate
output_folder: _bmad-output
tea_use_playwright_utils: true
tea_use_mcp_enhancements: false

Canonical Schema (Source of Truth)

Location: src/bmm/module.yaml

Purpose: Defines available configuration keys, defaults, and installer prompts

Created By: BMAD maintainers (part of BMAD repo)

Status: Versioned in BMAD repository

Usage: Reference only (do not edit unless contributing to BMAD)

Note: The installer reads module.yaml to prompt for config values, then writes user choices to _bmad/bmm/config.yaml in your project.

TEA Configuration Options

tea_use_playwright_utils

Enable Playwright Utils integration for production-ready fixtures and utilities.

Schema Location: src/bmm/module.yaml:52-56

User Config: _bmad/bmm/config.yaml

Type: boolean

Default: false (set via installer prompt during installation)

Installer Prompt:

Are you using playwright-utils (@seontechnologies/playwright-utils) in your project?
You must install packages yourself, or use test architect's *framework command.

Purpose: Enables TEA to:

• Include playwright-utils in *framework scaffold
• Generate tests using playwright-utils fixtures
• Review tests against playwright-utils patterns
• Configure CI with burn-in and selective testing utilities

Affects Workflows:

• *framework - Includes playwright-utils imports and fixture examples
• *atdd - Uses fixtures like apiRequest, authSession in generated tests
• *automate - Leverages utilities for test patterns
• *test-review - Reviews against playwright-utils best practices
• *ci - Includes burn-in utility and selective testing

Example (Enable):

tea_use_playwright_utils: true

Example (Disable):

tea_use_playwright_utils: false

Prerequisites:

npm install -D @seontechnologies/playwright-utils

Related:

• Integrate Playwright Utils Guide
• Playwright Utils on npm

tea_use_mcp_enhancements

Enable Playwright MCP servers for live browser verification during test generation.

Schema Location: src/bmm/module.yaml:47-50

User Config: _bmad/bmm/config.yaml

Type: boolean

Default: false

Installer Prompt:

Test Architect Playwright MCP capabilities (healing, exploratory, verification) are optionally available.
You will have to setup your MCPs yourself; refer to https://docs.bmad-method.org/explanation/features/tea-overview for configuration examples.
Would you like to enable MCP enhancements in Test Architect?

Purpose: Enables TEA to use Model Context Protocol servers for:

• Live browser automation during test design
• Selector verification with actual DOM
• Interactive UI discovery
• Visual debugging and healing

Affects Workflows:

• *test-design - Enables exploratory mode (browser-based UI discovery)
• *atdd - Enables recording mode (verify selectors with live browser)
• *automate - Enables healing mode (fix tests with visual debugging)

MCP Servers Required:

Two Playwright MCP servers (actively maintained, continuously updated):

• playwright - Browser automation (npx @playwright/mcp@latest)
• playwright-test - Test runner with failure analysis (npx playwright run-test-mcp-server)

Configuration example:

{
  "mcpServers": {
    "playwright": {
      "command": "npx",
      "args": ["@playwright/mcp@latest"]
    },
    "playwright-test": {
      "command": "npx",
      "args": ["playwright", "run-test-mcp-server"]
    }
  }
}

Configuration: Refer to your AI agent's documentation for MCP server setup instructions.

Example (Enable):

tea_use_mcp_enhancements: true

Example (Disable):

tea_use_mcp_enhancements: false

Prerequisites:

1. MCP servers installed in IDE configuration
2. @playwright/mcp package available globally or locally
3. Browser binaries installed (npx playwright install)

Core BMM Configuration (Inherited by TEA)

TEA also uses core BMM configuration options from _bmad/bmm/config.yaml:

output_folder

Type: string

Default: _bmad-output

Purpose: Where TEA writes output files (test designs, reports, traceability matrices)

Example:

output_folder: _bmad-output

TEA Output Files:

• test-design-system.md (from *test-design system-level)
• test-design-epic-N.md (from *test-design epic-level)
• test-review.md (from *test-review)
• traceability-matrix.md (from *trace Phase 1)
• gate-decision-{gate_type}-{story_id}.md (from *trace Phase 2)
• nfr-assessment.md (from *nfr-assess)
• automation-summary.md (from *automate)
• atdd-checklist-{story_id}.md (from *atdd)

---

user_skill_level

Type: enum

Options: beginner | intermediate | expert

Default: intermediate

Purpose: Affects how TEA explains concepts in chat responses

Example:

user_skill_level: beginner

Impact on TEA:

• Beginner: More detailed explanations, links to concepts, verbose guidance
• Intermediate: Balanced explanations, assumes basic knowledge
• Expert: Concise, technical, minimal hand-holding

---

project_name

Type: string

Default: Directory name

Purpose: Used in TEA-generated documentation and reports

Example:

project_name: my-awesome-app

Used in:

• Report headers
• Documentation titles
• CI configuration comments

---

communication_language

Type: string

Default: english

Purpose: Language for TEA chat responses

Example:

communication_language: english

Supported: Any language (TEA responds in specified language)

---

document_output_language

Type: string

Default: english

Purpose: Language for TEA-generated documents (test designs, reports)

Example:

document_output_language: english

Note: Can differ from communication_language - chat in Spanish, generate docs in English.

---

Environment Variables

TEA workflows may use environment variables for test configuration.

Test Framework Variables

Playwright:

# .env
BASE_URL=https://todomvc.com/examples/react/dist/
API_BASE_URL=https://api.example.com
TEST_USER_EMAIL=test@example.com
TEST_USER_PASSWORD=password123

Cypress:

# cypress.env.json or .env
CYPRESS_BASE_URL=https://example.com
CYPRESS_API_URL=https://api.example.com

CI/CD Variables

Set in CI platform (GitHub Actions secrets, GitLab CI variables):

# .github/workflows/test.yml
env:
  BASE_URL: ${{ secrets.STAGING_URL }}
  API_KEY: ${{ secrets.API_KEY }}
  TEST_USER_EMAIL: ${{ secrets.TEST_USER }}

---

Configuration Patterns

Development vs Production

Separate configs for environments:

# _bmad/bmm/config.yaml
output_folder: _bmad-output

# .env.development
BASE_URL=http://localhost:3000
API_BASE_URL=http://localhost:4000

# .env.staging
BASE_URL=https://staging.example.com
API_BASE_URL=https://api-staging.example.com

# .env.production (read-only tests only!)
BASE_URL=https://example.com
API_BASE_URL=https://api.example.com

Team vs Individual

Team config (committed):

# _bmad/bmm/config.yaml.example (committed to repo)
project_name: team-project
output_folder: _bmad-output
tea_use_playwright_utils: true
tea_use_mcp_enhancements: false

Individual config (typically gitignored):

# _bmad/bmm/config.yaml (user adds to .gitignore)
user_name: John Doe
user_skill_level: expert
tea_use_mcp_enhancements: true  # Individual preference

Monorepo Configuration

Root config:

# _bmad/bmm/config.yaml (root)
project_name: monorepo-parent
output_folder: _bmad-output

Package-specific:

# packages/web-app/_bmad/bmm/config.yaml
project_name: web-app
output_folder: ../../_bmad-output/web-app
tea_use_playwright_utils: true

# packages/mobile-app/_bmad/bmm/config.yaml
project_name: mobile-app
output_folder: ../../_bmad-output/mobile-app
tea_use_playwright_utils: false

---

Configuration Best Practices

1. Use Version Control Wisely

Commit:

_bmad/bmm/config.yaml.example    # Template for team
.nvmrc                            # Node version
package.json                      # Dependencies

Recommended for .gitignore:

_bmad/bmm/config.yaml            # User-specific values
.env                              # Secrets
.env.local                        # Local overrides

2. Document Required Setup

In your README:

## Setup

1. Install BMad

2. Copy config template:
   cp _bmad/bmm/config.yaml.example _bmad/bmm/config.yaml

3. Edit config with your values:
   - Set user_name
   - Enable tea_use_playwright_utils if using playwright-utils
   - Enable tea_use_mcp_enhancements if MCPs configured

3. Validate Configuration

Check config is valid:

# Check TEA config is set
cat _bmad/bmm/config.yaml | grep tea_use

# Verify playwright-utils installed (if enabled)
npm list @seontechnologies/playwright-utils

# Verify MCP servers configured (if enabled)
# Check your IDE's MCP settings

4. Keep Config Minimal

Don't over-configure:

# ❌ Bad - overriding everything unnecessarily
project_name: my-project
user_name: John Doe
user_skill_level: expert
output_folder: custom/path
planning_artifacts: custom/planning
implementation_artifacts: custom/implementation
project_knowledge: custom/docs
tea_use_playwright_utils: true
tea_use_mcp_enhancements: true
communication_language: english
document_output_language: english
# Overriding 11 config options when most can use defaults

# ✅ Good - only essential overrides
tea_use_playwright_utils: true
output_folder: docs/testing
# Only override what differs from defaults

Use defaults when possible - only override what you actually need to change.

Troubleshooting

Configuration Not Loaded

Problem: TEA doesn't use my config values.

Causes:

1. Config file in wrong location
2. YAML syntax error
3. Typo in config key

Solution:

# Check file exists
ls -la _bmad/bmm/config.yaml

# Validate YAML syntax
npm install -g js-yaml
js-yaml _bmad/bmm/config.yaml

# Check for typos (compare to module.yaml)
diff _bmad/bmm/config.yaml src/bmm/module.yaml

Playwright Utils Not Working

Problem: tea_use_playwright_utils: true but TEA doesn't use utilities.

Causes:

1. Package not installed
2. Config file not saved
3. Workflow run before config update

Solution:

# Verify package installed
npm list @seontechnologies/playwright-utils

# Check config value
grep tea_use_playwright_utils _bmad/bmm/config.yaml

# Re-run workflow in fresh chat
# (TEA loads config at workflow start)

MCP Enhancements Not Working

Problem: tea_use_mcp_enhancements: true but no browser opens.

Causes:

1. MCP servers not configured in IDE
2. MCP package not installed
3. Browser binaries missing

Solution:

# Check MCP package available
npx @playwright/mcp@latest --version

# Install browsers
npx playwright install

# Verify IDE MCP config
# Check ~/.cursor/config.json or VS Code settings

Config Changes Not Applied

Problem: Updated config but TEA still uses old values.

Cause: TEA loads config at workflow start.

Solution:

1. Save _bmad/bmm/config.yaml
2. Start fresh chat
3. Run TEA workflow
4. Config will be reloaded

TEA doesn't reload config mid-chat - always start fresh chat after config changes.
