How we built Kane CLI Exploration: an AI agent that maps a web app with no written requirements, flags problems, and turns the map into tests a person reviews.

Kane CLI Exploration walks your web app in up to 20 cloud browsers, maps every screen and flow, flags bugs, and hands the map to Assurance to write your tests.

How to test OpenAI Agents SDK agents: offline ScriptedModel tests, handoff and guardrail assertions, hidden tool errors, and checks on what the run changed.

How to test Claude Agent SDK agents: hermetic runs, hooks that record every tool call, subagent checks, guardrail tests, and evidence of what the run changed.

Agent harness vs eval harness: what each does, why one model scored 58% to 76% across agent harnesses, and how to test both harnesses before you trust a score.

How to build an eval harness for AI agents: task files, isolated trials, evidence-based graders, an unverified verdict, pass^k over repeat runs, and a CI gate.

Agent Assurance is now self-serve. Sign up, start a 14-day trial, test how your AI agents behave across tools and actions, and upgrade whenever you're ready.

Test on iPhone Duo with TestMu AI: live sessions on a real phone on iOS 27, an iOS 27.1 simulator, and the Safari viewport its outer screen gives your pages.

TestMu AI (formerly LambdaTest) vs UiPath Test Cloud: compare agentic test authoring, real devices, enterprise apps, pricing and deployment side by side.

I ran one 8-test Playwright suite on a laptop, a cloud grid, and HyperExecute, then ranked 11 test execution tools on parallel runs, retries, and CI fit.

LangSmith vs Braintrust, checked against each vendor's own docs: tracing, scorers, CI gates, pricing meters and self-hosting, plus a scorer test on 20 inputs.

Langfuse vs Phoenix compared from source files: MIT vs Elastic License 2.0, a six-service stack vs one process, OpenInference mapping, evals and 2026 owners.

Braintrust vs Langfuse, compared from their public code: what each license covers, what self-hosting each takes, Brainstore vs ClickHouse, evals and CI gates.

The eMudhra certificate compromise shows why patched is not proven: a passing browser or curl check says little about the TLS path your real app actually uses.

Snowflake automation testing checks dashboards, Streamlit apps, Cortex Agents and dbt changes against Snowflake SQL API queries, with Kane CLI runs to copy.

A timed Selenium to Playwright migration with AI: an agent using TestMu AI's migration skill converted 8 tests, fixed 3 failures, and passed in 41 minutes.

AI assurance checks whether an AI system meets its criteria. Learn the UK DSIT techniques, how it differs from observability and evals, and what AI agents need.
