Testing the Untestable: How to Validate Cloud‑Dependent Features You Don’t Fully Own and Control

Today’s software relies on a collection of cloud services, shared platforms, and third‑party tools, many of which your teams don’t own, control, or even fully understand. Yet when something goes wrong, customers don’t blame the cloud provider or the external API. They blame your product. That puts testers in a tough spot: how do you ensure quality when key parts of the system are unpredictable, unavailable, or outside your team’s reach? This session explores how to build confidence in features that depend on other teams and the ever‑changing cloud. The session will look at practical ways to understand your dependencies, anticipate problems before they happen, and design tests that reflect real‑world conditions — even when you can’t force those conditions to occur on demand. You’ll learn how to collaborate more effectively across teams, how to communicate risk clearly, and how to create a testing approach that keeps your product reliable even when the cloud isn’t. Whether you work in healthcare, finance, SaaS, or any environment where your system relies on someone else’s system, this talk will give you strategies to stay in control of quality when you don’t control the whole picture.
