About Aldi
Aldi is a global supermarket chain with more than 1,000 stores in the UK. Its first UK store opened in 1990, and the business now operates across 11 UK regions as part of a wider international presence.
For this project, Aldi was upgrading and patching its SAP Hybris ecommerce platform and needed confidence that changes underneath the experience had not introduced problems into the journeys customers relied on.
The challenge
Platform upgrades can change much more than the part of the system being worked on.
Aldi’s SAP Hybris upgrade touched infrastructure supporting product browsing, basket, checkout, customer accounts, promotions, and connected systems.
That created regression risk across the customer journey. A change in one area could surface as a completely different problem somewhere else.
Before deployment, Aldi needed a clear view of what the upgrade had affected and which issues posed the greatest risk to customers.
Our solution
Digivante ran an exploratory testing programme across the upgraded platform, comparing behaviour against the pre-upgrade experience.
Testing covered:
- Core ecommerce journeys: Homepage, search, product pages, basket, checkout, and customer accounts
- Regression testing: Checking whether existing functionality still behaved correctly following the upgrade
- Integrations: Looking for problems across systems connected to SAP Hybris
- Usability: Identifying friction introduced or exposed by the platform changes
- Conversion-critical journeys: Giving particular attention to the areas customers relied on to browse and buy
The approach allowed testers to investigate beyond a narrow script and follow knock-on effects as they appeared across the experience.
The results
Digivante identified 84 issues introduced or exposed during the upgrade.
Of those, 24 were classified as high severity, with the potential to affect customers’ ability to browse, purchase, or manage their accounts.
Because testing took place before deployment, Aldi had a prioritised view of what needed attention while the upgraded platform was still being prepared for release.
Core areas including basket, checkout, and customer accounts were independently tested rather than relying solely on internal sign-off.

The takeaway
An upgrade can be technically successful and still introduce problems into the customer experience.
The risk is particularly high when shared platform infrastructure supports multiple journeys and integrations at once.
For Aldi, independent regression and exploratory testing exposed 84 issues before deployment, including 24 high-severity defects.
That gave the team evidence of what the upgrade had changed in practice, not just whether the upgrade itself had completed successfully.
FAQs
Why did Aldi bring in Digivante?
Aldi was upgrading and patching its SAP Hybris ecommerce platform and needed to understand whether those changes had introduced problems across important customer journeys before deployment.
What did Digivante test for Aldi?
Testing covered homepage, search, product pages, basket, checkout, customer accounts, integrations, usability, and regression against the pre-upgrade experience.
What did the testing find?
Digivante identified 84 issues, including 24 high-severity defects, before the upgraded platform was deployed to customers.
Why is independent testing important after a platform upgrade?
Platform changes can affect several connected journeys at once. Independent exploratory and regression testing can expose knock-on problems across integrations and customer journeys that may not be obvious when teams focus only on the component being upgraded.
