Streamlining Performance and Personalization: Enhancing the Digital Shopping Experience for Interlink

Interlink is a company that provides various services to improve the digital shopping experience and streamline online business operations. Their solutions are designed to enhance website performance and user experience and implement advanced tools to drive efficiency and business growth. 

Before our specialist was introduced, developers periodically unit-tested the system. The project struggled with performance issues, unreliable integration with third-party services, and inconsistencies in complex user workflows and localized content. 

The client requested manual testing of the main functionality. We provided a multi-skilled specialist who performed manual testing and implemented and configured the automation process. During the project, our QA specialist faced several challenges directly linked to its distinctive features and is excited to have the opportunity to share this valuable experience with you:

In this project, such technologies were used: 

• Jira is responsible for bug tracking and project management, ensuring efficient issue tracking and resolution. 
• Postman for API testing, ensuring reliable and robust backend services. 
• Playwright & JavaScript were chosen for automated testing, ensuring interface consistency across web platforms. 
• Appium for comprehensive mobile application testing, ensuring functionality and performance across different mobile devices. 
• JMeter for performance and load testing, simulating peak traffic conditions to identify and address performance issues. 
• OWASP ZAP is used to identify vulnerabilities and ensure data security compliance. 

A unique feature implemented in this project was dynamic personalization testing. This involved simulating various user profiles and behaviors to ensure that personalized content and recommendations were accurately and effectively delivered. By creating advanced test scenarios, our team was able to verify that each user received a tailored experience, significantly enhancing engagement and satisfaction. This approach ensured that the platform could dynamically adjust its offerings based on real-time data, providing a more personalized and engaging user experience. 

The focused improvements in QA processes led to significant platform enhancements: 

• 500+ manual tests were created to increase code coverage by tests. 
• 300+ test cases were automated to reduce the time for regression testing. 
• 150 bug reports were generated to reduce the number of bugs detected in production. 
• 50% decrease in user-reported issues, thanks to the new real-time tracking system.  
• Enhanced security and compliance with data protection regulations, confirmed by rigorous security testing and vulnerability assessments.
