How ASDA, one of the UK's leading retail giants, scaled mobile testing and enhanced efficiency with Perfecto AI.
" We've seen significant progress in our test coverage to date! Perfecto AI is highly beneficial, particularly with new features being introduced that enable us to cover both web and mobile apps. The navigation tool feature will further reduce the development time for our automation scripts and is expected to enhance the long-term maintainability of those scripts."
Overview
ASDA, one of the UK's leading retail giants, faced significant challenges in scaling their mobile device testing processes. As they continuously evolve to stay ahead in a dynamic industry, dependency on physical hardware, concerns around security, and resource limitations were major roadblocks to efficient testing. By implementing Perfecto AI, ASDA transformed its testing workflows, increasing coverage, improving efficiency, and significantly reducing manual intervention.

This case study explores ASDA's challenges, how Perfecto helped address them, and the measurable results achieved.
By the Numbers
- Reduced Manual Testing Efforts by 70%.
- Increased Test Coverage by 50%.
- 4x Increase in Device & OS Coverage
- Reduced Test Execution Time from Days to Hours.
The Challenge
ASDA's team consistently adapts to maintain their edge in an ever-changing industry. In working towards their objectives, they recognized the need to address hurdles in their application testing processes, which created delays in releasing their S&G app updates and increased regression risk:
- Limited Testing Resources: Testing mobile apps required physical devices to be on-site with the team, which limited the growth they were working to achieve.
- Manual Testing Overhead: Heavy reliance on manual testing created bottlenecks and reduced efficiency. By tackling bottlenecks caused by manual testing, they sought to boost productivity and overall workflow.
- Device Sharing Issues: A lack of a scalable solution for sharing devices across multiple projects and team members further strained resources.

ASDA realized that these challenges hindered their ability to deliver high-quality applications across platforms, such as their Scan & Go and Rewards apps. ASDA’s focus on delivering at a quicker pace within their engineering teams and changing customer demands meant they needed to deliver faster than ever before. They sought an enterprise-grade solution to streamline processes and improve coverage while keeping pace with future innovation.
What Was at Stake
Without a scalable and efficient solution, ASDA risked:
- Failing to meet tight project timelines.
- Increased potential for errors and regression due to insufficient test coverage.
- Bottlenecks in testing delivery, which would affect business goals, from customer experience improvements to promotional rollouts.
The Solution
ASDA selected Perfecto as their enterprise solution to address these challenges. Through its powerful AI-powered platform, Perfecto offered the scalability, reliability, and efficiency ASDA needed.
Implementation Highlights
- AI-Driven Coverage: ASDA utilized Perfecto AI to test critical applications, including their new ecommerce website, their ASDA mobile app, and changes to their Scan & Go feature and Rewards app. Perfecto AI offered automation for areas that were traditionally difficult to test, such as validating images and ensuring promotions appeared in the right place with accurate content.
- Seamless Zebra Device Integration: ASDA transformed their testing processes by integrating Perfecto with their Zebra devices, which are used in their many stores and depots, so they needed a solution that would integrate with their existing infrastructure. Perfecto fully supported ASDA's Zebra devices, including their scanners, enabling smooth data handling through the DataWedge app. This allowed barcode data to pass directly into mobile applications, eliminating the need for manual barcode scanning. Perfecto also helped to successfully test and validate ASDA’s essential mobile apps, such as Scan & Go, ensuring reliable performance and compatibility across environments. This high level of hardware integration was truly a game changer for ASDA.
- Hybrid Cloud Deployment: Perfecto’s hybrid cloud setup provided ASDA with flexibility to host devices themselves, enhancing control and security while maintaining scalability. With Perfecto, ASDA teams could test on multiple devices hosted in a hybrid cloud setup, eliminating the need for physical hardware.
ASDA’s decision to adopt Perfecto was based on its adaptability to their unique requirements, such as its ability to work seamlessly with Zebra devices, and the collaborative approach of the Perfecto team.
