When discussing the process of testing an API, one of the most common sets of terms you might encounter are “mocks” and “stubs.” These terms are quite ubiquitous, but understanding exactly how they differ from one another - and when each is the correct method for software testing - is critical to building an appropriate test and validation framework. In this blog, we’re going to talk about the differences and similarities between mocks and stubs.

Static delivery pipelines are becoming a bottleneck. The best CI/CD tools for Kubernetes are those that move beyond simple code builds to provide total environment orchestration and developer self-service.

Harness has been recognized by TechStrong Group for its comprehensive, AI-native platform vision, winning Best End-to-End DevOps Platform, Best Platform Engineering Solution, and DevOps Industry Leader of the Year. At Harness, our mission has always been simple but ambitious: to enable every software engineering team in the world to deliver code reliably, efficiently, and quickly to their users, just like the world’s leading tech companies.

Infrastructure code rarely stays clean on its own. Teams move fast, and reviews aren’t always deep or consistent. Over time, misconfigurations build up and increase the risk of outages, security gaps, or unpredictable behavior. Static scanning tools can help, but they often require setup, expertise, and don’t always reflect how infrastructure code is actually used across environments. Code Optimizer, now in beta, helps teams catch those issues earlier.

VictoriaMetrics is a fast, cost-efficient, and highly scalable time-series database designed as a drop-in replacement for Prometheus storage. It is widely used for collecting, storing, and querying metrics at scale, while remaining lightweight enough to run as a single binary or container. Because it is fully Prometheus-compatible, VictoriaMetrics supports standard PromQL queries and integrates seamlessly with Grafana.

The dust has settled on Las Vegas. We saw transparent TVs, cars that drive sideways, and enough “AI-powered” toothbrushes to confuse a dentist. CES is incredible at selling the dream of hardware. The demos are slick, the lighting is perfect, and everything works on the showroom floor. But as engineers, we know the dirty secret of CES: The hardware is the easy part.

Observability pricing often seems reasonable at the outset, but many organizations discover their real complexity only as environments scale and usage patterns change. As environments grow more complex and hybrid by default, many organizations struggle with rising costs, fragmented tools, and pricing models that complicate cost predictability and long-term planning.
