Spring GDS 25th Anniversary
A logistics company that ships to 190 countries built something to ship to itself.
Acceptance testing
What is acceptance testing?
Acceptance testing is the check that happens before something ships. Not a developer reviewing their own code. A product, feature, or system evaluated against the requirements agreed before anyone started building.
User acceptance testing (UAT) brings in real end users or their proxies. They work through real workflows, not scripted demos. Business acceptance testing (BAT) checks the product against the business requirements defined at the project's start. Both depend on acceptance criteria written in advance, typically from user stories, that make "done" a measurable standard rather than a feeling. A checkout flow that passes unit tests but breaks under a real purchase is exactly what acceptance testing catches.
In Agile development, acceptance testing runs alongside sprints rather than waiting until the end. The definition of done includes it. Every feature that passes moves forward. Every feature that doesn't goes back. That cycle is what keeps a product honest.
Acceptance testing at Dallonses
Every feature we ship goes through acceptance testing before it closes. Not a quality promise on the website. It's how we structure sprints.
We write acceptance criteria with clients at the start of a project, before development begins. When a sprint ends, user acceptance testing is part of the review. Software quality assurance isn't a phase scheduled at the end. It's built into every definition of done. When something fails, it doesn't ship. We fix it and run the check again. Production stays clean. The relationship stays honest.
Shipping something that needs to hold up under real conditions? Let's make sure it does.
