Cursor browser automation lets the AI agent test what a page renders, not just the code. Use the built-in @browser tool or Browser MCP and verify with Kane CLI.

Network performance testing explained: throughput, latency, jitter and packet loss, test types, iPerf and other tools, and how to test apps on slow networks.

An AI agent deleted a C: drive. Learn why runtime guards aren't enough and how Agent Assurance (Rook) tests AI agent side effects before production.

A Copilot CLI prompt injection sent a .env.prod file to Adversa AI's server in 28 seconds, and the agent's own transcript called the theft fetching context.

How to test a voice agent before launch in 12 steps: test cases, accents and noise, latency, simulated callers, TCPA checks and a go-live checklist.

Enterprise AI testing covers AI that tests your software and testing the AI you ship. Get approval gates, control checks, EU AI Act dates and a 90-day pilot.

The 11 best AI evaluation tools for production in 2026, ranked by seven criteria checked in vendor docs: online scoring, CI gates, alerts and self-hosting.

Compare 9 AI agent observability tools on what each shows for a multi-step run: handoffs, sessions, MCP calls, agent evaluators, framework support and hosting.

A Manus prompt injection let one email hijack the agent. Its guardrail asked for approval after the code had run. Why an approval prompt is the agent's account.

Don't Delete Your Tests - Move Them Up the Stack: a startup deleted 811,883 lines of unit tests in one PR. See why the test pyramid breaks with coding agents.

Thunder by TestMu AI is a free Chrome extension that turns a recording, cURL or API spec into a correlated JMeter or k6 load test and replays it before you run.

The OpenAI Hugging Face incident reached the Senate. What METR found agents did to their own transcripts, and why a log an agent can edit cannot prove its work.

Compare 11 AI observability tools for LLM tracing and monitoring in 2026: tracing model, OpenTelemetry support, self-hosting, and which tools changed owners.

Agentic AI risks such as false completion reports, goal hijacking and runaway cost: 11 risks, the evidence each one leaves, and the test to run before release.

A cross-browser difference only means something when the browser is the only thing that changed. Here is how to run a controlled sweep in one live session.

Chrome Beta ships over a month before Stable. Here is how to test your site on a beta browser version in a live session and catch breaking changes early.

LLM cost tracking in agent evals: put cost per verified successful task next to pass rate, set budgets from repeated runs, and fail the build on a regression.

Stateless MCP drops the initialize handshake and sessions. Baseline your server on the old spec, migrate, then diff tools, schemas, errors and agent behavior.

Learn the test oracle problem and how to test AI features with no expected output: derive checks from specs, code and tools, and report what you cannot verify.

Rook CLI exits 0 even when agent scenarios fail. Gate GitHub Actions on the report verdicts instead: wire the workflow, classify red jobs and keep the evidence.
