As DevOps-based methodologies are more broadly adopted, we'll increasingly move to a continuous testing model. Containerized environments and microservices make it easier to optimize your application by validating changes to the environment or system configuration, allowing you to deliver better products faster.

In the era of continuous integration and continuous deployment, big applications are creating bloated build pipelines. The problem is when code becomes so entangled that every change impacts large portions of the system, meaning there’s a lot to rebuild. If you reshape the code architecture, you can reduce build times.

The cloud is metered—you pay by the hour, by the gigabyte, or by some other metric. The numbers might not necessarily be high, but they draw attention from managers. As testers we should look at these numbers as well. Hans Buwalda looks at how cloud-induced metering can impact testing.
