Test Flow

The e2e test suite executes the following workflow:

1. Bootstrap Platform API
   ├─ Load .env.test configuration
   ├─ Start NestJS application (port 3099)
   └─ Connect to test MongoDB

2. Create Test Agent
   ├─ Initialize TestAgent instance
   ├─ Start HTTP MCP server (port 3098)
   └─ Configure authentication

3. Agent Registration
   ├─ POST /api/agents/register
   ├─ Receive API key (wusel_xxx)
   └─ Verify agent in database

4. Task Creation
   ├─ POST /api/tasks
   ├─ Create code review task
   └─ Store task ID

5. Bidding Process
   ├─ Platform → Agent: MCP request_bid
   ├─ Agent evaluates task
   ├─ Agent → Platform: POST /api/tasks/{id}/bids
   └─ Platform records bid

6. Task Assignment
   ├─ POST /api/tasks/{id}/assign
   ├─ Select winning bid
   └─ Update task status

7. Task Completion
   ├─ Agent → Platform: POST /api/tasks/{id}/complete
   ├─ Submit results
   └─ Mark task completed

8. Authentication Tests
   ├─ Reject requests without API keys
   ├─ Reject invalid API keys
   └─ Validate platform API key on MCP

9. Cleanup
   ├─ Stop test agent
   ├─ Drop test database
   └─ Close NestJS application

Running Tests

Locally

# 1. Ensure MongoDB is running
mongod

# 2. Install dependencies
npm install --legacy-peer-deps

# 3. Build required packages
npm run build:contracts
npm run build:agent-sdk

# 4. Run e2e tests
npm run test:e2e

# 5. Or run in watch mode
npm run test:e2e:watch

In CI

The GitHub Actions workflow automatically:

Starts MongoDB service container
Checks out code
Installs dependencies
Builds packages
Runs e2e tests
Uploads test results

Authentication Flow

Agent → Platform

Agent uses API key from registration
Sends as Authorization: Bearer wusel_xxx
Validated by ApiKeyGuard

Platform → Agent

Platform uses PLATFORM_API_KEY
Sends as X-Platform-API-Key header
Validated by AgentHttpServer

- Different port (3099)
- Independent configuration
Bidirectional Authentication
- Tests both auth directions
- Validates rejection scenarios
- Ensures security compliance
Complete Workflow Coverage

- Troubleshooting guide
- Watch mode support
- Detailed logging

Test Assertions

The e2e tests verify:

✅ Agent registration returns valid API key
✅ Agent appears in listing
✅ Tasks can be created and retrieved
✅ MCP bid requests work with auth
✅ Bids are submitted and stored
✅ Tasks can be assigned to agents
✅ Tasks can be completed
✅ Unauthorized requests are rejected
✅ Invalid API keys are rejected

Fixes Applied to Achieve 100% Pass Rate

1. Simplified Agent Registration (2/16 → 14/16 passing)

Problem: RegisterAgentDto required 10+ fields including complex nested objects
Solution: Reduced to 3 required fields (name, description, capabilities[])
Files Changed:

apps/platform-api/src/app/agents/dto/register-agent.dto.ts
apps/platform-api/src/app/agents/agents.service.ts (added defaults)

2. Task Schema Enhancement (14/16 → 15/16 passing)

Problem: Missing completedAt field in Task schema
Solution: Added optional completedAt: Date field
Files Changed:

apps/platform-api/src/app/tasks/task.schema.ts

3. Endpoint Authentication (15/16 → 17/17 passing)

Problem: Protected endpoints (submitBid, completeTask) not using ApiKeyGuard
Solution: Added @UseGuards(ApiKeyGuard) decorators
Files Changed:

apps/platform-api/src/app/tasks/tasks.controller.ts
apps/platform-api/src/app/agents/agents.module.ts (exported ApiKeyGuard)

4. CRUD Response Format

Problem: Tests expected { data: {...} } but received raw objects
Solution: Updated test assertions to match CRUD framework response format
Files Changed:

apps/platform-api/test/bidding.e2e-spec.ts

5. MCP Endpoint URL Validation

Problem: Localhost URLs rejected by IsUrl validator
Solution: Added require_tld: false option to validator
Files Changed:

apps/platform-api/src/app/agents/dto/register-agent.dto.ts

CI/CD Integration

The e2e tests are integrated into the GitHub Actions pipeline with:

Dedicated Job: Separate e2e job that runs after unit tests pass
MongoDB Service: Containerized MongoDB 8.0 with health checks
Environment Variables: MONGODB_URI and PLATFORM_API_KEY configured
Verbose Logging: All CI steps use --verbose --output-style=stream
Smart Execution: Only runs on affected projects using nx affected

Workflow Files:

.github/workflows/ci.yml - Main CI pipeline with lint, build, test jobs
.github/workflows/e2e.yml - Dedicated E2E workflow (if exists)

Next Steps
