Testlio Delivers Global E-Commerce Confidence for High-End Retailer Through Scalable Testing

A high-end fashion and beauty brand relies on Testlio to power seamless e-commerce experiences and secure transactions in every market, across every language, device, and payment system.

The Challenge

For a luxury fashion brand with a high average order value, even a single failed transaction is costly, both financially and reputationally. The company needed a way to ensure smooth, reliable, and high-quality e-commerce performance across a wide range of devices, languages, and payment systems while rolling out major platform upgrades and routine feature releases.

Solution

The designer label’s global digital team needed a scalable, international QA partner to match its ambitious expansion goals. Testlio’s ability to execute comprehensive testing across locations, languages, and devices, while delivering actionable feedback at speed, made us the ideal partner.

• Functional testing across 250+ devices

• Language and localization validation in 20+ regions

• Support for platform upgrades and regular releases

• Payment method testing across a broad geographic footprint

• Scalable team of 157 testers to match release needs

With over 213 test runs completed in 20+ countries, Testlio’s global delivery model enabled the brand to confidently meet the quality demands of international luxury commerce.
