# Test Tier Selection
Automatic guidance for selecting appropriate test tiers based on change context and scope.
## Test Tier Definitions
| Tier | Duration | Scope | When to Run |
|------|----------|-------|-------------|
| **Unit** | < 30s | Single function/module | After every code change |
| **Integration** | < 5min | Component interactions | After feature completion |
| **E2E** | < 30min | Full user flows | Before commit/PR |
## Decision Matrix
### Change Type → Test Tier
| Change Type | Unit | Integration | E2E |
|-------------|------|-------------|-----|
| Single function fix | Required | Skip | Skip |
| New feature (1 file) | Required | Required | Skip |
| Multi-file feature | Required | Required | Required |
| Refactoring | Required | Required | Optional |
| API changes | Required | Required | Required |
| UI changes | Required | Optional | Required |
| Bug fix (isolated) | Required | Optional | Skip |
| Database changes | Required | Required | Required |
| Config changes | Required | Required | Optional |
## Escalation Signals
**Escalate to Integration when:**
- Changes span multiple files
- Business logic affected
- Service boundaries modified
- Database queries changed
**Escalate to E2E when:**
- User-facing features modified
- Authentication/authorization changes
- Critical path functionality
- Before creating PR
## Commands by Tier
```bash
# Tier 1: Unit (fast feedback)
/test:quick
# Tier 2: Integration (feature completion)
/test:full --coverage
# Tier 3: E2E (pre-commit)
/test:full
```
## Agent Consultation Triggers
**Consult `test-architecture` agent when:**
- New feature module created
- Coverage drops > 5%
- > 3 flaky tests detected
- Framework questions arise
- Test strategy needs adjustment
**Consult `test-runner` agent when:**
- Need test execution with analysis
- Multiple failures to diagnose
- Want concise failure summary
**Consult `system-debugging` agent when:**
- Integration test failures with unclear cause
- Environment/timing issues
- Flaky tests related to concurrency
## Quick Reference
### After Small Change
```
1. Run /test:quick
2. If pass: Continue working
3. If fail: Fix immediately
```
### After Feature Completion
```
1. Run /test:full --coverage
2. Check coverage targets met
3. If gaps: /test:consult coverage
```
### Before Commit/PR
```
1. Run /test:full
2. All tiers must pass
3. Review coverage report
```
### For New Features
```
1. /test:consult new-feature
2. Write tests (TDD)
3. Run /test:quick during development
4. Run /test:full before PR
```
## Activation Triggers
This skill auto-activates when:
- User mentions "test", "run tests", "testing"
- After code modification by Claude
- During TDD workflow
- When `/test:*` commands invoked
- When discussing test strategy
