Testing AI Systems for Risk: Bias, Accuracy, and Robustness Checks
Traditional software has deterministic behavior: the same input always produces the same output. AI systems break this contract.

EU AI Act Testing Guide: What Developers Need to Test Before August 2026
The EU AI Act became enforceable in phases starting 2024, but August 2026 marks the deadline for full obligations on high-risk AI systems.

Testing AI Chatbots: End-to-End QA for Conversational AI Systems
AI chatbots fail in ways that traditional software doesn't. They misunderstand intent, lose context across turns, make up information, break character, and occasionally say things that would horrify your legal team. Testing them requires a different mental model from testing deterministic systems — you're testing behaviors under

LLM Hallucination Testing: Strategies to Detect Fabricated AI Outputs
LLMs hallucinate. They generate plausible-sounding text that is factually wrong, cite papers that don't exist, quote statistics that were never measured, and confidently describe events that never happened. If your product uses an LLM to generate content that users trust — customer support answers, medical information, legal summaries,

ML Model Regression Testing: Catch Model Degradation Before Production
ML models degrade in ways that traditional software doesn't. Code doesn't spontaneously get worse — but a model trained on March data can silently degrade by June as the distribution of real-world inputs shifts. A retrained model can score higher on aggregate metrics while regressing on

A/B Testing AI Features: Experiments With Guardrails for LLM Products
A/B testing AI features is harder than testing traditional software. Changing a button color produces a measurable, binary outcome — users click or they don't. Changing an LLM prompt produces different text outputs, and measuring which output is "better" requires defining what better even means for

Getting Started with AI-Powered Test Automation
AI has changed what's possible in test automation. The traditional approach — writing code to drive browsers, maintaining brittle selectors, spending hours fixing tests when UI changes — is no longer the only option. AI-powered test automation lets you describe tests in plain language, generates test steps from user

LLM Output Regression Testing: Catch Prompt Regressions Before Users Do
Every time you change a prompt, update a model version, modify your retrieval pipeline, or adjust a system instruction, you've potentially introduced a regression. Unlike traditional software regressions — where a function returns the wrong value and a unit test catches it — LLM regressions are subtle. The output format

Portkey AI Gateway Testing: Rate Limits, Fallbacks, and Routing
Most LLM applications fail at the infrastructure layer, not the model layer. Your prompt is fine. Your retrieval is fine.
