Testing AI with AI: Why Deterministic Frameworks Fail at Chatbot Validation and What Actually Works | Harness Blog

Chatbots are becoming ubiquitous. Customer support, internal knowledge bases, developer tools, healthcare portals - if it has a user interface, someone is shipping a conversational AI layer on top of it. And the pace is only accelerating. But here's the problem nobody wants to talk about: we still don’t have a reliable way to test these chatbots at scale. Not because testing is new to us. We've been testing software for decades.

The Path to AI-Ready Operations Begins with Truth

Enterprises expect AI to improve how they operate, yet many underestimate the level of clarity required for intelligent systems to perform reliably. AI-assisted operations demand input signals that are accurate, consistent, and interpretable. They require a unified understanding of how services behave, how disruptions originate, and how decisions influence downstream outcomes. This level of coherence is impossible without operational truth.

Peak traffic without the panic: auto-scaling infrastructure for ecommerce flash sales

Key takeaway: Upsun replaces manual, high-stress peak traffic prep with automatic scaling, keeping your e-commerce site fast and available during flash sales while you only pay for the resources you consume. For every e-commerce team, an outage means lost revenue, failed checkouts, and a flood of support tickets. For most stores, this gets worse during peak events like Black Friday and flash sales.

CEO Fireside at HumanX: Resilience at the Speed of Change

PagerDuty CEO and Chairperson Jennifer Tejada in conversation on April 8, 2026 at HumanX in San Francisco with Honeycomb CEO Christine Yen and journalist Jennifer Strong, show how observability and real-time response help builders spot issues sooner, fix them faster, and learn from every incident.

Building a single pane of glass for enterprise Kubernetes fleets

A Kubernetes single pane of glass is a centralized management layer that unifies visibility, access control, cost allocation, and policy enforcement across § cluster in an enterprise fleet for all cloud providers. It replaces the fragmented practice of switching between AWS, GCP, and Azure consoles to govern infrastructure, giving platform teams a single source of truth for multi-cloud Kubernetes operations.

Sample AI traces at 100% without sampling everything

A little while ago, when agents were telling me “You’re absolutely right!”, I was building webvitals.com. You put in a URL, it kicks off an API request to a Next.js API route that invokes an agent with a few tools to scan it and provide AI generated suggestions to improve your… you guessed it… Web Vitals. Do we even care about these anymore?

Spending More, Seeing Less: How Indexing Limits Capital Markets Visibility

Capital markets systems don’t scale linearly. A macro event, an earnings release, a sudden liquidity shift, and telemetry volume doubles in seconds. In most observability platforms today, that spike means one thing: every byte gets written to a high-cost index before a single query can touch it. There’s no middle ground. You pay full indexing cost for the compliance log that no one queries for six months, the same way you pay for the execution trace you need right now.

Every engineering org is taking an AI readiness test right now

Tamar Bercovici has been at Box for 15 years. She leads the core platform, the backend layer that storage, search, metadata, and AI capabilities all run on. When her systems go down, Box goes down. On a recent episode of the Braintrust podcast, she said the debate around AI-generated code tends to focus on whether the models will write clean code and/or introduce bugs. Tamar's focus is somewhere else entirely.

Heroku vs AWS

Heroku vs AWS: these cloud platforms represent fundamentally different approaches to application cloud hosting. The decision between them often determines whether your team ships features in hours or spends days configuring infrastructure. Both platforms represent different philosophies in cloud computing, with Heroku prioritizing developer experience while AWS maximizes infrastructure control.
