CircleCI Smarter Testing Tutorial: Run Fewer Tests and Get Faster Feedback

CircleCI Smarter Testing is now generally available. In this tutorial, we’ll show you how Smarter Testing helps you run fewer tests, get faster feedback, and reduce unnecessary CI compute with three capabilities: Then, we’ll put it to the test. For the same code change, a traditional pipeline ran all 9,716 tests across 15 nodes. With Smarter Testing, CircleCI identified just 44 impacted tests and skipped the other 9,672, cutting test runtime from 3 minutes and 56 seconds to 22 seconds.

How to Connect Cursor to CircleCI: AI-Powered CI/CD Debugging

Stop manually pushing branches, hunting for logs, and pasting errors back into your editor. This video shows you how to connect Cursor to CircleCI using the CircleCI CLI so your AI agent can trigger pipelines, read build output, and fix failures autonomously without you ever leaving the IDE. In this demo, we introduce a bug, let CI catch it, and watch the agent diagnose and fix it on its own, monitoring the pipeline until it comes back green. No tab-switching. No copy-pasting logs.
