To guarantee a smooth user experience on an online video platform, rigorous load testing must be conducted across multiple system components. Every service, from user authentication to video playback, must be tested to manage peak traffic and prevent performance bottlenecks.

Key Testing Areas

Key areas that should be tested include:

• User Authentication & Registration – Ensuring login, sign-up, and session management can handle high concurrency.
• Subscription & Payment Processing – Testing transaction flows to prevent failures during peak purchase periods.
• Video Streaming & CDN Performance – Simulating heavy traffic to validate adaptive streaming and reduce buffering.
• API Performance – Evaluating response times for content retrieval, user profiles, and entitlement checks.
• Concurrent Live Streaming – Measuring system resilience when streaming to large audiences.
• Infrastructure & Auto-scaling – Ensuring the platform scales dynamically under load spikes.

By thoroughly testing these areas, the platform can maintain high availability, smooth playback, and a frictionless user experience - even during high-demand events like live sports broadcasts or new content releases.

🚧

Important Note

Load testing directly on Cleeng’s production or sandbox environments is strictly NOT allowed. Running large-scale tests against Cleeng’s live services can disrupt real users and exceed API rate limits. Instead, always use mock APIs to simulate Cleeng’s responses in your testing environment.

Our platform has extensive experience handling high-traffic events, including major live sports broadcasts, global pay-per-view events, and large-scale subscription services. We have successfully managed millions of concurrent viewers, ensuring smooth registrations, logins, secure transactions, and real-time entitlement checks.

With our scalable infrastructure and battle-tested performance, we guarantee that our platform can handle any load, providing a seamless experience for both content providers and end users.

Step-by-Step Guide

1. Identify Key APIs to Mock

The most commonly used Cleeng APIs for subscription-based platforms are:

• Customer Registration API (/customers) – Handles new user sign-ups
• Login API (/customers/auths) – Manages user authentication
• Entitlement API (/customers/entitlements) – Determines access to content

2. Use a Mocking Tool

You can create a mock API using:

• Postman Mock Server
• WireMock (local or cloud-based)
• Mockoon (easy-to-use desktop app)
• API Gateway with Mock Integration (e.g., AWS API Gateway)

3. Define Mock Responses

For each endpoint, create sample JSON responses that mirror Cleeng’s real API.

4. Configure Your Platform to Use the Mock API

Modify API base URLs in your test environment to point to the mock server instead of Cleeng’s live API.

5. Run Load Tests Against the Mock API

Using tools like JMeter, k6, or Locust, simulate:

• 100,000+ simultaneous entitlement checks
• High transaction volumes for subscription purchases
• Burst traffic scenarios during a live event

Conclusion

By mocking Cleeng APIs, you can conduct effective load tests on your platform without impacting Cleeng’s production services. This approach ensures your system is prepared for high traffic events while maintaining a stable subscription and payment experience.
