This is what a flaky test looks like
If a test passes and fails on the same commit, that’s flakiness.

Winning in the AI Era: How Top Teams are Driving Their Velocity Gains with Alloy & Chime
While most teams struggle with the complexity of AI-generated code, Alloy and Chime have built internal cultures and processes that enable them to scale their development while maintaining quality. Join CircleCI’s CTO, Rob Zuber, in conversation with Maciej Makowski, Senior Software Developer at Chime, and Sunny Singh, Senior Software Engineer at Alloy, as they explore the dynamics that set their teams apart. They'll talk through the culture and delivery practices that actually moved the needle.
Announcing the Next Chapter for Bitbucket Pipelines Runners
In December 2025, we announced our intention to introduce pricing for self-hosted runners so we could provide stronger support and keep investing in new features and ongoing improvements. You’ve told us that having a free option is important. As a result, we’re introducing a new operating model that lets you continue using self‑hosted runners for free with the option to upgrade to a paid premium runners tier as your needs grow.
AI debugging depends on this skill
The better you can describe a bug, the better AI can help fix it.
How to Plan a Successful CI/CD Migration Without Disrupting Developers | Harness Blog
Modern engineering teams run on CI/CD. It’s where pull requests get validated, artifacts get produced, and releases get promoted to production. That also makes CI/CD migration very risky because you're not just moving a "tool"; you're moving the workflow that developers use dozens or hundreds of times a day. The good news: disruption is optional.
CI/CD best practices | Harness Blog
Modern software teams are under constant pressure to ship faster without breaking production. That’s why CI/CD best practices have become essential for high-performing DevOps organizations. Continuous integration and continuous delivery (CI/CD) help automate builds, testing, and deployments — but simply installing a pipeline tool isn’t enough. Without the right practices, pipelines become slow, flaky, and difficult to govern.
Deployment strategies: Types, trade-offs, and how to choose
A deployment strategy is the method a team uses to move new code into a production environment. It determines how traffic shifts between versions, how much risk each release represents, and how quickly the team can roll back when something breaks. The choice isn’t academic: a mismatch between strategy and system can mean downtime, failed rollouts, or hours of manual recovery.
Rolling Deployments Explained: Seamless Software Delivery
In this video, Eric Minick from Harness explains the fundamentals of rolling deployments and how they help maintain a seamless user experience during software updates. Key topics covered include: Whether you are looking for simple implementation or consistent application uptime, rolling deployments offer a powerful strategy for modern software delivery. Learn more about Rolling Deployments and Harness Continuous Delivery.
Confident Commit | Loïc Houssier
Most engineering roadmaps are built around certainty, but that model is beginning to break down. When the way people interact with software is changing this quickly, exploration stops being a side project and starts becoming the day-to-day.
Code Coverage: Measure, Improve, and Scale Quality in CI | Harness Blog
Most engineering teams know the difference between “we have tests” and “we know we’re well-tested.” Your CI builds may be green, but without code coverage, it’s hard to prove how much of your code is actually exercised by automated tests. Code coverage measures what percentage of your code runs during tests (lines, branches, and functions), and when you wire it into CI gates, it becomes an enforceable quality signal and not a vanity metric.
