Testcase Execution Platform
Scalable, distributed system for authoring, executing, and analyzing Playwright-based web testcases with real-time SSE updates, queue-based orchestration, and artifact management
Feature Overview
Enterprise-grade test automation platform with distributed execution and real-time visibility
Core Features
- Step-based testcase authoring with intuitive UI
- Suite composition and execution configuration
- Multi-environment and multi-browser support
- Queue-based job distribution and orchestration
- Distributed Playwright worker execution
- Real-time execution updates via Server-Sent Events
- Artifact management (screenshots, videos, traces)
- CI/CD integration with REST API triggers
Advanced Features
- RBAC with project-level access control
- Encrypted secret management for test credentials
- Horizontal worker scaling based on queue depth
- Automatic retry and dead-letter queue handling
- Flaky test detection and analytics
- Time-limited signed URLs for artifact access
- Execution history and trend analysis
- Audit logging and compliance tracking
System Architecture
Modular, service-oriented architecture designed for scalability and fault tolerance
Web UI (React)
Test authoring, suite composition, execution monitoring, and artifact visualization
Backend API (Spring Boot / FastAPI)
Authentication, orchestration, validation, and REST endpoints for all operations
Queue System (Redis / RabbitMQ)
Async job distribution, buffering, and horizontal scaling enablement
Playwright Workers
Distributed test execution with artifact capture and result submission
PostgreSQL Database
Metadata storage for projects, testcases, runs, jobs, and step results
Object Storage (S3)
Artifact storage for screenshots, videos, traces, and logs
Execution Flow
Asynchronous, distributed workflow from test initiation to result aggregation
1. User Triggers Run
User selects suite, environment, and browser configuration in Web UI
2. Orchestrator Creates Jobs
Backend validates request, creates run record, and splits suite into individual jobs
3. Queue Distribution
Jobs are published to message queue with execution metadata and configuration
4. Worker Execution
Playwright workers consume jobs, launch browsers, execute steps, and capture artifacts
5. Result Submission
Workers upload artifacts to S3 and submit step results to backend API
6. Report Generation
Backend aggregates results, updates run status, and streams updates via SSE
Worker Capabilities
Playwright-based execution engine with comprehensive artifact capture and fault tolerance
Isolated Execution
Each job runs in fresh browser context with clean state and independent resources
Step Dispatching
Sequential execution of actions (click, type, navigate) with element validation
Screenshot Capture
Automatic screenshots on step completion and failure for visual debugging
Video Recording
Full session video capture for post-execution analysis and debugging
Trace Generation
Playwright trace files with timeline, network logs, and DOM snapshots
Retry Handling
Automatic retry logic with exponential backoff for transient failures
Key Benefits
Enterprise-grade test automation that scales with your organization
10x Faster Execution
Distributed workers enable parallel test execution, reducing suite runtime from hours to minutes
Real-Time Visibility
Server-Sent Events provide live execution updates, eliminating polling and enabling instant feedback
Fault Tolerant
Automatic retries, dead-letter queues, and idempotent processing ensure reliable execution at scale
Infinite Scalability
Horizontal worker scaling based on queue depth enables unlimited parallelization without bottlenecks
