# Requirements Engineering and Incremental Development Planning Sub-Agent
|
||||
|
||||
## Executive Summary
|
||||
|
||||
This specialized sub-agent was designed to prevent the interface compatibility issues and mock object mismatches encountered during Issue #59 debugging session. It provides a systematic approach to requirements engineering that ensures solid foundations before implementation.
|
||||
|
||||
## Problem Analysis: What Went Wrong in Issue #59
|
||||
|
||||
During the Issue #59 debugging session, several critical problems were identified:
|
||||
|
||||
### 1. Mock Object Mismatches
|
||||
- Tests created `Mock()` objects without `spec=` parameter
|
||||
- Mock attributes didn't match actual domain model attributes
|
||||
- Used strings instead of enums (e.g., `state = "open"` instead of `IssueState.OPEN`)
|
||||
- Missing required attributes like `created_at`, `updated_at`
|
||||
|
||||
### 2. Interface Compatibility Issues
|
||||
- Tests assumed interface methods that didn't exist in actual implementation
|
||||
- Async/sync mismatch between repository (async) and expected interface (sync)
|
||||
- Parameter type mismatches (string vs int for issue IDs)
|
||||
|
||||
### 3. Bottom-Up Structure Problems
|
||||
- Tests written without understanding existing domain model structure
|
||||
- Assumptions made about interface contracts without verification
|
||||
- No analysis of existing infrastructure before adding new layers
|
||||
|
||||
### 4. Integration Planning Failures
|
||||
- No clear plan for how new CLI would integrate with existing infrastructure
|
||||
- Missing adapter layers between async repositories and sync interfaces
|
||||
- No backward compatibility strategy
|
||||
|
||||

### Key Features
|
||||
|
||||
#### Domain Model First (DMF) Approach
|
||||
```bash
|
||||
# Before writing any tests, analyze existing domain models
|
||||
python tools/requirements_engineering_toolkit.py analyze
|
||||
```
|
||||
|
||||
#### Interface Contract Verification
|
||||
```python
|
||||
# Ensure mocks match actual domain models
|
||||
mock_issue = Mock(spec=Issue) # ✅ Use spec=
|
||||
mock_issue.state = IssueState.OPEN # ✅ Use actual enum
|
||||
```
|
||||
|
||||
#### Incremental Architecture Validation
|
||||
- Checkpoint-based development
|
||||
- Interface compatibility checking
|
||||
- Mock validation at each step
|
||||
|
||||
#### Foundation Assessment
|
||||
- Map existing interfaces before adding new ones
|
||||
- Understand dependency relationships
|
||||
- Plan integration points
|
||||
|
||||
## Practical Usage
|
||||
|
||||
### Quick Start Commands
|
||||
|
||||
```bash
|
||||
# 1. Before starting any new feature
|
||||
make validate-requirements
|
||||
|
||||
# 2. Plan interface evolution
|
||||
python tools/requirements_engineering_toolkit.py plan-interface --interface YourInterface
|
||||
|
||||
# 3. Generate development checklist
|
||||
python tools/requirements_engineering_toolkit.py checklist --feature "Your Feature"
|
||||
|
||||
# 4. Validate test mocks
|
||||
python tools/requirements_engineering_toolkit.py validate-mocks --test-file tests/your_test.py
|
||||
```
|
||||
|
||||
### Enhanced TDD8 Workflow
|
||||
|
||||
1. **ANALYZE** - Analyze existing domain models and interfaces
|
||||
2. **ISSUE** - Understand requirements in architectural context
|
||||
3. **TEST** - Write tests that match actual interfaces
|
||||
4. **RED** - Verify tests fail for right reasons
|
||||
5. **GREEN** - Implement with interface compatibility
|
||||
6. **REFACTOR** - Maintain interface contracts
|
||||
7. **DOCUMENT** - Update interface documentation
|
||||
8. **PUBLISH** - Commit with interface change documentation
|
||||
|
||||
### Integration with Existing Workflow
|
||||
|
||||
#### Makefile Enhancement
|
||||
```makefile
|
||||
# Add requirements validation to existing workflow
|
||||
tdd-start: validate-requirements
|
||||
python tddai_cli.py tdd-start $(NUM)
|
||||
|
||||
validate-requirements:
|
||||
python tools/requirements_engineering_toolkit.py analyze
|
||||
```
|
||||
|
||||
#### Pre-commit Validation
|
||||
```bash
|
||||
# Add to pre-commit hooks
|
||||
make validate-requirements
|
||||
python -m pytest tests/test_mock_compatibility.py
|
||||
```
|
||||
|
||||
## Specific Issue #59 Prevention
|
||||
|
||||
The agent would have prevented Issue #59 problems through:
|
||||
|
||||
### 1. Foundation Analysis
|
||||
- Would have discovered actual `Issue` domain model structure
|
||||
- Would have identified `IssueState` enum vs string requirement
|
||||
- Would have mapped existing `GiteaIssueRepository` interface
|
||||
|
||||
### 2. Interface Planning
|
||||
- Would have identified async/sync mismatch between repository and plugin interface
|
||||
- Would have planned adapter layer needed
|
||||
- Would have defined clear interface contracts
|
||||
|
||||
### 3. Mock Validation
|
||||
- Would have enforced `Mock(spec=Issue)` usage
|
||||
- Would have caught attribute mismatches before running tests
|
||||
- Would have ensured enum usage instead of strings
|
||||
|
||||
### 4. Integration Strategy
|
||||
- Would have planned how CLI integrates with existing infrastructure
|
||||
- Would have identified reusable components
|
||||
- Would have maintained backward compatibility
|
||||
|
||||
