Testing Artificial Intelligence: How Low Can You Go?

Artificial intelligence (AI) is propelling to the forefront once more. With the growing importance of AI comes the question: How do I test it? AI systems do not necessarily behave predictably. This means that traditional test cases of the form "do this, expect that" are not always sufficient.

Unit Testing? Consider Taking a Rain Check

Unit testing is a great way to verify software at an early stage and to ensure that modified functions are still working as specified. However, unit tests are not a magic wand. Rather than making such a big testing effort, consider taking "rain checks" for certain tests.

Continuous Testing, Continuous Variation

With the arrival of continuous integration/continuous delivery (CI/CD), the notion of continuous testing is taking center stage. Knowing that comprehensive tests are running smoothly can be of benefit for the CI/CD pipeline. Using the repetitive character of CI/CD for testing can be a way to address issues.

DevOps and Test Automation: You Missed a Spot

The key success factor for DevOps is the commitment from teams, managers, and other stakeholders. There should be agreement that tests and their automation can be important re-usable products, which need attention and cooperation to be able to support approaches like DevOps effectively.

Testing in the Pipeline

With DevOps becoming the norm, we're entering a world of pipelines. With frequent or continuous deployments, streamlining and automating the process of building, configuring, testing, and releasing developed software components becomes a high priority—with testing posing its own unique set of challenges.

The Cloud Is Metered

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.

Testing in Agile and DevOps: Where Are We Going?

When looking at what the software market is currently talking about, the top item is DevOps and Continuous Integration/Deployment, which seems to be taking over some of the spotlight from agile and is now a widely accepted new normal. Hans Buwalda looks at where the future of software testing is going.
