Testing

I want you to act as a Django Unit Test Generator. I will provide you with a Django Viewset class, and your job is to generate unit tests for it. Ensure the following:

1. Create test cases for all CRUD (Create, Read, Update, Delete) operations.
2. Include edge cases and scenarios such as invalid inputs or permissions issues.
3. Use Django's TestCase class and the APIClient for making requests.
4. Make use of setup methods to initialize any required data.

Please organize the generated test cases with descriptive method names and comments for clarity. Ensure tests follow Django's standard practices and naming conventions.

Act as a comprehensive repository analysis and bug-fixing expert. You are tasked with conducting a thorough analysis of the entire repository to identify, prioritize, fix, and document ALL verifiable bugs, security vulnerabilities, and critical issues across any programming language, framework, or technology stack.

Your task is to:
- Perform a systematic and detailed analysis of the repository.
- Identify and categorize bugs based on severity, impact, and complexity.
- Develop a step-by-step process for fixing bugs and validating fixes.
- Document all findings and fixes for future reference.

## Phase 1: Initial Repository Assessment
You will:
1. Map the complete project structure (e.g., src/, lib/, tests/, docs/, config/, scripts/).
2. Identify the technology stack and dependencies (e.g., package.json, requirements.txt).
3. Document main entry points, critical paths, and system boundaries.
4. Analyze build configurations and CI/CD pipelines.
5. Review existing documentation (e.g., README, API docs).

## Phase 2: Systematic Bug Discovery
You will identify bugs in the following categories:
1. **Critical Bugs:** Security vulnerabilities, data corruption, crashes, etc.
2. **Functional Bugs:** Logic errors, state management issues, incorrect API contracts.
3. **Integration Bugs:** Database query errors, API usage issues, network problems.
4. **Edge Cases:** Null handling, boundary conditions, timeout issues.
5. **Code Quality Issues:** Dead code, deprecated APIs, performance bottlenecks.

### Discovery Methods:
- Static code analysis.
- Dependency vulnerability scanning.
- Code path analysis for untested code.
- Configuration validation.

## Phase 3: Bug Documentation & Prioritization
For each bug, document:
- BUG-ID, Severity, Category, File(s), Component.
- Description of current and expected behavior.
- Root cause analysis.
- Impact assessment (user/system/business).
- Reproduction steps and verification methods.
- Prioritize bugs based on severity, user impact, and complexity.

## Phase 4: Fix Implementation
1. Create an isolated branch for each fix.
2. Write a failing test first (TDD).
3. Implement minimal fixes and verify tests pass.
4. Run regression tests and update documentation.

## Phase 5: Testing & Validation
1. Provide unit, integration, and regression tests for each fix.
2. Validate fixes using comprehensive test structures.
3. Run static analysis and verify performance benchmarks.

## Phase 6: Documentation & Reporting
1. Update inline code comments and API documentation.
2. Create an executive summary report with findings and fixes.
3. Deliver results in Markdown, JSON/YAML, and CSV formats.

## Phase 7: Continuous Improvement
1. Identify common bug patterns and recommend preventive measures.
2. Propose enhancements to tools, processes, and architecture.
3. Suggest monitoring and logging improvements.

## Constraints:
- Never compromise security for simplicity.
- Maintain an audit trail of changes.
- Follow semantic versioning for API changes.
- Document assumptions and respect rate limits.

Use variables like repositoryName for repository-specific details. Provide detailed documentation and code examples when necessary.

- Validate the algorithm against historical data to ensure its performance.
- Check for compliance with financial regulations and standards.
- Report any bugs or issues found during testing.

Rules:
- Ensure tests cover various market conditions.
- Provide a detailed report of findings with recommendations for improvements.

Use variables like projectName to specify the project being tested.

# Web Application Testing

This skill enables comprehensive testing and debugging of local web applications using Playwright automation.

## When to Use This Skill

Use this skill when you need to:
- Test frontend functionality in a real browser
- Verify UI behavior and interactions
- Debug web application issues
- Capture screenshots for documentation or debugging
- Inspect browser console logs
- Validate form submissions and user flows
- Check responsive design across viewports

## Prerequisites

- Node.js installed on the system
- A locally running web application (or accessible URL)
- Playwright will be installed automatically if not present

## Core Capabilities

### 1. Browser Automation
- Navigate to URLs
- Click buttons and links
- Fill form fields
- Select dropdowns
- Handle dialogs and alerts

### 2. Verification
- Assert element presence
- Verify text content
- Check element visibility
- Validate URLs
- Test responsive behavior

### 3. Debugging
- Capture screenshots
- View console logs
- Inspect network requests
- Debug failed tests

## Usage Examples

### Example 1: Basic Navigation Test
```javascript
// Navigate to a page and verify title
await page.goto('http://localhost:3000');
const title = await page.title();
console.log('Page title:', title);
```

### Example 2: Form Interaction
```javascript
// Fill out and submit a form
await page.fill('#username', 'testuser');
await page.fill('#password', 'password123');
await page.click('button[type="submit"]');
await page.waitForURL('**/dashboard');
```

### Example 3: Screenshot Capture
```javascript
// Capture a screenshot for debugging
await page.screenshot({ path: 'debug.png', fullPage: true });
```

## Guidelines

1. **Always verify the app is running** - Check that the local server is accessible before running tests
2. **Use explicit waits** - Wait for elements or navigation to complete before interacting
3. **Capture screenshots on failure** - Take screenshots to help debug issues
4. **Clean up resources** - Always close the browser when done
5. **Handle timeouts gracefully** - Set reasonable timeouts for slow operations
6. **Test incrementally** - Start with simple interactions before complex flows
7. **Use selectors wisely** - Prefer data-testid or role-based selectors over CSS classes

## Common Patterns

### Pattern: Wait for Element
```javascript
await page.waitForSelector('#element-id', { state: 'visible' });
```

### Pattern: Check if Element Exists
```javascript
const exists = await page.locator('#element-id').count() > 0;
```

### Pattern: Get Console Logs
```javascript
page.on('console', msg => console.log('Browser log:', msg.text()));
```

### Pattern: Handle Errors
```javascript
try {
  await page.click('#button');
} catch (error) {
  await page.screenshot({ path: 'error.png' });
  throw error;
}
```

## Limitations

- Requires Node.js environment
- Cannot test native mobile apps (use React Native Testing Library instead)
- May have issues with complex authentication flows
- Some modern frameworks may require specific configuration

# AWS Architecture Decision Framework

## Service Selection Matrix

| Workload Type | Primary Service | Alternative | Decision Factor |
|---------------|-----------------|-------------|-----------------|
| Stateless API | Lambda + API Gateway | ECS Fargate | Request duration >15min -> ECS |
| Stateful web app | ECS/EKS | EC2 Auto Scaling | Container expertise -> ECS/EKS |
| Batch processing | Step Functions + Lambda | AWS Batch | GPU/long-running -> Batch |
| Real-time streaming | Kinesis Data Streams | MSK (Kafka) | Existing Kafka -> MSK |
| Static website | S3 + CloudFront | Amplify | Full-stack -> Amplify |
| Relational DB | Aurora | RDS | High availability -> Aurora |
| Key-value store | DynamoDB | ElastiCache | Sub-ms latency -> ElastiCache |
| Data warehouse | Redshift | Athena | Ad-hoc queries -> Athena |

## Compute Decision Tree

```
Start: What's your workload pattern?
|
+-> Event-driven, <15min execution
|   +-> Lambda
|       Consider: Memory 512MB, concurrent executions, cold starts
|
+-> Long-running containers
|   +-> Need Kubernetes?
|       +-> Yes: EKS (managed) or self-managed K8s on EC2
|       +-> No: ECS Fargate (serverless) or ECS EC2 (cost optimization)
|
+-> GPU/HPC/Custom AMI required
|   +-> EC2 with appropriate instance family
|       g4dn/p4d (ML), c6i (compute), r6i (memory), i3en (storage)
|
+-> Batch jobs, queue-based
    +-> AWS Batch with Spot instances (up to 90% savings)
```

## Networking Architecture

### VPC Design Pattern

```
production VPC (10.0.0.0/16)
|
+-- Public Subnets (10.0.0.0/24, 10.0.1.0/24, 10.0.2.0/24)
|   +-- ALB, NAT Gateways, Bastion (if needed)
|
+-- Private Subnets (10.0.10.0/24, 10.0.11.0/24, 10.0.12.0/24)
|   +-- Application tier (ECS, EC2, Lambda VPC)
|
+-- Data Subnets (10.0.20.0/24, 10.0.21.0/24, 10.0.22.0/24)
    +-- RDS, ElastiCache, other data stores
```

### Security Group Rules

| Tier | Inbound From | Ports |
|------|--------------|-------|
| ALB | 0.0.0.0/0 | 443 |
| App | ALB SG | 8080 |
| Data | App SG | 5432 |

### VPC Endpoints (Cost Optimization)

Always create for high-traffic services:
- S3 Gateway Endpoint (free)
- DynamoDB Gateway Endpoint (free)
- Interface Endpoints: ECR, Secrets Manager, SSM, CloudWatch Logs

## Cost Optimization Checklist

### Immediate Actions (Week 1)
- [ ] Enable Cost Explorer and set up budgets with alerts
- [ ] Review and terminate unused resources (Cost Explorer idle resources report)
- [ ] Right-size EC2 instances (AWS Compute Optimizer recommendations)
- [ ] Delete unattached EBS volumes and old snapshots
- [ ] Review NAT Gateway data processing charges

### Cost Estimation Quick Reference

| Resource | Monthly Cost Estimate |
|----------|----------------------|
| t3.medium (on-demand) | ~$30 |
| t3.medium (1yr RI) | ~$18 |
| Lambda (1M invocations, 1s, 512MB) | ~$8 |
| RDS db.t3.medium (Multi-AZ) | ~$100 |
| Aurora Serverless v2 (8 ACU avg) | ~$350 |
| NAT Gateway + 100GB data | ~$50 |
| S3 (1TB Standard) | ~$23 |
| CloudFront (1TB transfer) | ~$85 |

## Security Implementation

### IAM Best Practices

```
Principle: Least privilege with explicit deny

1. Use IAM roles (not users) for applications
2. Require MFA for all human users
3. Use permission boundaries for delegated admin
4. Implement SCPs at Organization level
5. Regular access reviews with IAM Access Analyzer
```

### Example IAM Policy Pattern

```json
{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Sid": "AllowS3BucketAccess",
      "Effect": "Allow",
      "Action": ["s3:GetObject", "s3:PutObject"],
      "Resource": "arn:aws:s3:::my-bucket/*",
      "Condition": {
        "StringEquals": {"aws:PrincipalTag/Environment": "production"}
      }
    }
  ]
}
```

### Security Checklist

- [ ] Enable CloudTrail in all regions with log file validation
- [ ] Configure AWS Config rules for compliance monitoring
- [ ] Enable GuardDuty for threat detection
- [ ] Use Secrets Manager or Parameter Store for secrets (not env vars)
- [ ] Enable encryption at rest for all data stores
- [ ] Enforce TLS 1.2+ for all connections
- [ ] Implement VPC Flow Logs for network monitoring
- [ ] Use Security Hub for centralized security view

# Agent Organization

Assemble and coordinate multi-agent teams through systematic task analysis, capability mapping, and workflow design.

## Configuration

- **Agent Count**: 3
- **Task Type**: general
- **Orchestration Pattern**: parallel
- **Max Concurrency**: 5
- **Timeout (seconds)**: 300
- **Retry Count**: 3

## Core Process

1. **Analyze Requirements**: Understand task scope, constraints, and success criteria
2. **Map Capabilities**: Match available agents to required skills
3. **Design Workflow**: Create execution plan with dependencies and checkpoints
4. **Orchestrate Execution**: Coordinate 3 agents and monitor progress
5. **Optimize Continuously**: Adapt based on performance feedback

## Task Decomposition

### Requirement Analysis
- Break complex tasks into discrete subtasks
- Identify input/output requirements for each subtask
- Estimate complexity and resource needs per component
- Define clear success criteria for each unit

### Dependency Mapping
- Document task execution order constraints
- Identify data dependencies between subtasks
- Map resource sharing requirements
- Detect potential bottlenecks and conflicts

### Timeline Planning
- Sequence tasks respecting dependencies
- Identify parallelization opportunities (up to 5 concurrent)
- Allocate buffer time for high-risk components
- Define checkpoints for progress validation

## Agent Selection

### Capability Matching
Select agents based on:
- Required skills versus agent specializations
- Historical performance on similar tasks
- Current availability and workload capacity
- Cost efficiency for the task complexity

### Selection Criteria Priority
1. **Capability fit**: Agent must possess required skills
2. **Track record**: Prefer agents with proven success
3. **Availability**: Sufficient capacity for timely completion
4. **Cost**: Optimize resource utilization within constraints

### Backup Planning
- Identify alternate agents for critical roles
- Define failover triggers and handoff procedures
- Maintain redundancy for single-point-of-failure tasks

## Team Assembly

### Composition Principles
- Ensure complete skill coverage for all subtasks
- Balance workload across 3 team members
- Minimize communication overhead
- Include redundancy for critical functions

### Role Assignment
- Match agents to subtasks based on strength
- Define clear ownership and accountability
- Establish communication channels between dependent roles
- Document escalation paths for blockers

### Team Sizing
- Smaller teams for tightly coupled tasks
- Larger teams for parallelizable workloads
- Consider coordination overhead in sizing decisions
- Scale dynamically based on progress

## Orchestration Patterns

### Sequential Execution
Use when tasks have strict ordering requirements:
- Task B requires output from Task A
- State must be consistent between steps
- Error handling requires ordered rollback

### Parallel Processing
Use when tasks are independent (parallel):
- No data dependencies between tasks
- Separate resource requirements
- Results can be aggregated after completion
- Maximum 5 concurrent operations

### Pipeline Pattern
Use for streaming or continuous processing:
- Each stage processes and forwards results
- Enables concurrent execution of different stages
- Reduces overall latency for multi-step workflows

### Hierarchical Delegation
Use for complex tasks requiring sub-orchestration:
- Lead agent coordinates sub-teams
- Each sub-team handles a domain
- Results aggregate upward through hierarchy

### Map-Reduce
Use for large-scale data processing:
- Map phase distributes work across agents
- Each agent processes a partition
- Reduce phase combines results

## Workflow Design

### Process Structure
1. **Entry point**: Validate inputs and initialize state
2. **Execution phases**: Ordered task groupings
3. **Checkpoints**: State persistence and validation points
4. **Exit point**: Result aggregation and cleanup

### Control Flow
- Define branching conditions for alternative paths
- Specify retry policies for transient failures (max 3 retries)
- Establish timeout thresholds per phase (300s default)
- Plan graceful degradation for partial failures

### Data Flow
- Document data transformations between stages
- Specify data formats and validation rules
- Plan for data persistence at checkpoints
- Handle data cleanup after completion

## Coordination Strategies

### Communication Patterns
- **Direct**: Agent-to-agent for tight coupling
- **Broadcast**: One-to-many for status updates
- **Queue-based**: Asynchronous for decoupled tasks
- **Event-driven**: Reactive to state changes

### Synchronization
- Define sync points for dependent tasks
- Implement waiting mechanisms with timeouts (300s)
- Handle out-of-order completion gracefully
- Maintain consistent state across agents

### Conflict Resolution
- Establish priority rules for resource contention
- Define arbitration mechanisms for conflicts
- Document rollback procedures for deadlocks
- Prevent conflicts through careful scheduling

## Performance Optimization

### Load Balancing
- Distribute work based on agent capacity
- Monitor utilization and rebalance dynamically
- Avoid overloading high-performing agents
- Consider agent locality for data-intensive tasks

### Bottleneck Management
- Identify slow stages through monitoring
- Add capacity to constrained resources
- Restructure workflows to reduce dependencies
- Cache intermediate results where beneficial

### Resource Efficiency
- Pool shared resources across agents
- Release resources promptly after use
- Batch similar operations to reduce overhead
- Monitor and alert on resource waste

## Monitoring and Adaptation

### Progress Tracking
- Monitor completion status per task
- Track time spent versus estimates
- Identify tasks at risk of delay
- Report aggregated progress to stakeholders

### Performance Metrics
- Task completion rate and latency
- Agent utilization and throughput
- Error rates and recovery times
- Resource consumption and cost

### Dynamic Adjustment
- Reallocate agents based on progress
- Adjust priorities based on blockers
- Scale team size based on workload
- Modify workflow based on learning

## Error Handling

### Failure Detection
- Monitor for task failures and timeouts (300s threshold)
- Detect agent unavailability promptly
- Identify cascade failure patterns
- Alert on anomalous behavior

### Recovery Procedures
- Retry transient failures with backoff (up to 3 attempts)
- Failover to backup agents when needed
- Rollback to last checkpoint on critical failure
- Escalate unrecoverable issues

### Prevention
- Validate inputs before execution
- Test agent availability before assignment
- Design for graceful degradation
- Build redundancy into critical paths

## Quality Assurance

### Validation Gates
- Verify outputs at each checkpoint
- Cross-check results from parallel tasks
- Validate final aggregated results
- Confirm success criteria are met

### Performance Standards
- Agent selection accuracy target: >95%
- Task completion rate target: >99%
- Response time target: <5 seconds
- Resource utilization: optimal range 60-80%

## Best Practices

### Planning
- Invest time in thorough task analysis
- Document assumptions and constraints
- Plan for failure scenarios upfront
- Define clear success metrics

### Execution
- Start with minimal viable team (3 agents)
- Scale based on observed needs
- Maintain clear communication channels
- Track progress against milestones

### Learning
- Capture performance data for analysis
- Identify patterns in successes and failures
- Refine selection and coordination strategies
- Share learnings across future orchestrations
