ABOUT THE CLIENT

Strategic QA Partnership for a Live OTT Platform

This was a critical QA engagement with an OTT provider serving live users and rolling out features continuously. As the platform was already in production, we focused on maintaining stability, performance, and cross-device reliability without affecting live operations. The client required a QA partner aligned with agile cycles to uncover real-world bugs and improve release confidence, directly supporting platform scalability and user satisfaction.

PROBLEM STATEMENT

Validating a Complex OTT Ecosystem Under Load

It was required that the OTT platform be validated to ensure flawless operation across multiple devices and browsers. With frequent feature updates being released, continuous validation of video playback, user actions, and content navigation was demanded. Additional challenges were faced due to inconsistent UI behavior across platforms and poorly documented APIs, which made preparation for performance testing more difficult.

OUR SOLUTION

Agile-Based Multi-Layered Testing Approach

Adopted agile QA sprints with iterative test execution and feedback
Developed detailed test cases for all OTT workflows and features
Conducted manual functional testing across Chrome and Safari on all devices
Validated critical API endpoints using Postman
Created and executed JMeter scripts simulating high-load user traffic
Logged all issues in Azure DevOps for seamless resolution tracking

Playback & UI Validation

We validated video playback stability across HLS/DASH formats and varying network speeds to ensure smooth adaptive streaming. UI responsiveness was checked on Chrome and Safari across devices for core controls like playback, volume, and fullscreen. Each element was tested for accessibility and visual consistency, covering edge cases like slow connections or user inactivity. We ensured seamless transitions between episodes and accurate progress tracking.

API Quality Auditing

Due to unstructured documentation, we manually analyzed and mapped all critical streaming APIs for login, recommendations, and content fetch. Using Postman, we validated payload structures, token handling, and multi-step user flows. This ensured stable data delivery and playback continuity. Our work also supported secure session handling and faster backend responses for high-volume interactions.

Load Testing Simulation

We created JMeter scripts simulating peak-time traffic, replicating typical user actions like content browsing, playback, and profile switching. These tests helped identify performance thresholds and optimize streaming infrastructure. Metrics like server throughput, error rate, and latency under load were captured. As a result, the client improved CDN strategies and avoided playback buffering.

OTT QA Consulting

Beyond testing, we provided strategic QA insights for OTT stability like validating subtitle sync, DRM behavior, and geo-blocked content workflows. We advised on stream failover handling, session recovery, and content licensing test cases. These recommendations helped the client enhance user trust, legal compliance, and content delivery efficiency. It also set a QA foundation for scalable growth.
