Ensuring a seamless shift for legacy system migration of a leading Ed-Tech platform in Japan by implementing scalable test automation

Summary

This case study explores the successful implementation of long-term test automation solutions during a company-wide legacy system migration for a prominent educational technology platform in Japan. Shift Asia partnered with the client to analyze automation scope, develop a robust framework, build and execute test scripts, and provide ongoing maintenance, focusing on API and API-UI integration testing.

About the Client

The client delivers home-teaching and educational programs through various channels, including mobile apps, browser-based applications, and in-class systems supported by government institutions. The client embarked on a large-scale initiative to modernize its outdated technological infrastructure to maintain its competitive edge and ensure efficient service delivery.

Challenges

Extensive and complex legacy systems built on outdated technologies.
Inefficient testing processes reliant on manual efforts.
Need for a smooth transition to a unified system with improved performance and maintainability.

Solutions & results

SHIFT ASIA proposed and implemented a comprehensive test automation plan encompassing both API and API-UI integration testing, including:

• Development of a scalable and sustainable automation framework: Leveraging their proprietary Ballista framework for API testing and utilizing Selenium and Playwright for API-UI integration automation.
• Automation script creation and execution: Covering key functionalities and integrations across the new system.
• Maintenance and optimization: Continuously enhancing the automation suite to adapt to system updates and evolving requirements.

Approaches

SHIFT ASIA actively collaborated with the client’s internal testing team, providing expert guidance and technical support throughout the project. A dedicated test engineer worked closely with the client’s testers team of ten, ensuring seamless communication and knowledge transfer.
