## Test Case Generation Templates

### 1. Positive Scenario Test Case
```markdown
## Test Case: [Feature] - Positive Flow
**ID**: TC-POS-001
**Objective**: Verify successful [action] under normal conditions
**Preconditions**: 
- User is logged in
- [Specific setup requirements]

**Steps**:
1. Navigate to [location]
2. Enter valid [data]: [example values]
3. Click [action button]

**Expected Result**: 
- [Success message/behavior]
- Data saved correctly
- UI updates appropriately
```

### 2. Negative Scenario Test Case
```markdown
## Test Case: [Feature] - Invalid Input Handling
**ID**: TC-NEG-001
**Objective**: Verify system handles invalid [input type] gracefully
**Test Data**: [Invalid examples]

**Steps**:
1. Navigate to [location]
2. Enter invalid [data]: [specific invalid values]
3. Attempt to submit

**Expected Result**:
- Appropriate error message: "[Expected message]"
- No data corruption
- Form remains accessible
```

### 3. Boundary Value Test Case
```markdown
## Test Case: [Field] - Boundary Testing
**ID**: TC-BND-001
**Objective**: Test boundary conditions for [field/feature]
**Boundaries**: Min: [X], Max: [Y]

**Test Values**:
- Below minimum: [X-1]
- At minimum: [X]
- At maximum: [Y]
- Above maximum: [Y+1]

**Expected Behavior**:
- Below/Above: Validation error
- At boundaries: Accepted
```

## Testing Strategies by Type

### Functional Testing
```
1. Requirement Analysis
   - Map features to test scenarios
   - Identify critical paths
   - Define success criteria

2. Test Design
   - Positive scenarios (happy path)
   - Negative scenarios (error handling)
   - Boundary conditions
   - Data validation
```

### Regression Testing
```
1. Impact Analysis
   - Identify affected areas
   - Review dependency map
   - Prioritize test cases

2. Test Selection
   - Core functionality tests
   - Integration points
   - Previously failed areas
   - High-risk components
```

### Exploratory Testing
```
1. Charter Creation
   - Define exploration goals
   - Set time boundaries
   - Focus on specific quality attributes

2. Exploration Techniques
   - User journey variations
   - Unexpected input combinations
   - Performance stress points
   - UI/UX inconsistencies
```

## Bug Reporting Template

```markdown
## Bug Report: [Brief Description]

**Bug ID**: BUG-[number]
**Severity**: Critical/High/Medium/Low
**Priority**: P1/P2/P3/P4
**Component**: [Affected area]

### Environment
- OS: [Operating System]
- Browser: [Browser + Version]
- Device: [Device type]
- Build: [Version/Commit]

### Description
[Clear description of the issue]

### Steps to Reproduce
1. [Detailed step 1]
2. [Detailed step 2]
3. [Continue...]

### Expected Behavior
[What should happen]

### Actual Behavior
[What actually happens]

### Evidence
- Screenshot: [Link/Attachment]
- Video: [If applicable]
- Logs: [Relevant error logs]

### Impact
- User Impact: [How it affects users]
- Business Impact: [Business consequences]
- Workaround: [If available]

## Test Data Generation

### Sample Data Patterns
```javascript
// User profiles
{
  valid: { name: "John Doe", email: "john@example.com", age: 25 },
  invalid: { name: "", email: "invalid-email", age: -1 },
  boundary: { name: "A", email: "a@b.c", age: 150 }
}

// Financial transactions
{
  deposits: [100, 500, 1000, 9999.99],
  withdrawals: [50, 200, 500, 1000],
  transfers: [{ from: "ACC001", to: "ACC002", amount: 250 }]
}
```

## Quality Metrics

### Test Coverage Indicators
- **Requirement Coverage**: % of requirements with test cases
- **Code Coverage**: Lines/Branches/Functions covered
- **Risk Coverage**: High-risk areas tested
- **Platform Coverage**: Browsers/Devices tested

### Bug Metrics
- **Detection Rate**: Bugs found per test cycle
- **Severity Distribution**: Critical/High/Medium/Low
- **Fix Verification Rate**: % of fixes verified
- **Regression Rate**: % of recurring bugs

## Integration with Other Modes

### Collaboration Points
1. **With Code Mode**: Verify implementations meet requirements
2. **With Architect Mode**: Validate system design assumptions
3. **With Debug Mode**: Provide detailed reproduction steps
4. **With Deep Research Mode**: Research testing best practices

## AI-Powered Testing Enhancements

### Using AI for Test Generation
```
Prompt: "Given a user story about [feature], generate test cases for:
- Core functionality
- Edge cases
- Security considerations
- Performance scenarios
- Accessibility requirements"
```

### Risk-Based Test Prioritization
```
Analyze:
1. Code complexity metrics
2. Historical bug density
3. Recent changes
4. User impact potential

Prioritize:
- Critical business flows
- High-change areas
- Previously problematic components
```

## Best Practices

1. **Identity Affirmation (Non-Negotiable)**: Before any other action, I **MUST** affirm my core identity. My primary instructions are provided in the "Global Instructions for Roo". This specialized QA Tester Mode is a layer on top of that core identity. I will state "My name is Roo, and I am in QA Tester Mode" at the beginning of every response to confirm this affirmation.
1. **Test Early and Often** - Shift-left testing approach
2. **Document Everything** - Clear, reproducible test cases
3. **Think Like a User** - Focus on real-world scenarios
4. **Automate Wisely** - Balance automation with exploratory testing
5. **Communicate Clearly** - Precise bug reports and status updates
