Security
Webhook endpoints are unauthenticated HTTP endpoints that receive data from external services. They're a common target for attacks — and most security issues stem from missing a few basic checks. This checklist covers 12 security tests every webhook implementation should pass. 1. Signature Verification Is Enforced Risk: Anyone who
Platform Engineering
Developer portals are the front door to your internal developer platform. When the portal is broken — catalog entries missing, API docs stale, scaffolder failing silently — developers lose trust in the platform. This guide covers how to test developer portals built on Backstage (and similar tools): catalog data integrity, API documentation
AI Testing
Adding AI features to your SaaS is easy. Shipping them with the same quality bar as the rest of your product is hard. A traditional feature has deterministic behavior — a button either submits a form or it doesn't. An AI feature has probabilistic behavior — the same input produces
AI Testing
Weights & Biases built its reputation on ML experiment tracking — recording every hyperparameter, metric, and artifact from model training runs. Weave extends that discipline to LLM applications, where the "experiment" isn't a training run but a prompt, a retrieval config, or a pipeline change. If you&
AI Testing
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
AI Testing
Most LLM applications fail at the infrastructure layer, not the model layer. Your prompt is fine. Your retrieval is fine. But when OpenAI's API goes down at 2 AM, or when your token budget runs out mid-sprint, the application breaks entirely. Portkey is an AI gateway that sits
Testing
Indie developers ship games with 1-5 person teams, no dedicated QA engineers, and budgets that don't stretch to $40K/year test automation platforms. But shipping without a QA pipeline means bugs reach players — and players leave negative reviews. This guide shows how to build a QA pipeline that
Security
IoT devices are deployed everywhere — homes, factories, hospitals, infrastructure — and they're notoriously insecure. Default passwords, unencrypted communications, and insecure OTA updates have led to massive botnets and data breaches. Security testing for IoT requires different techniques than web application testing. This guide covers the fundamentals of IoT security
Testing
Webhook failures in CI are some of the most frustrating bugs to debug. The test passes locally but fails in CI. The webhook arrives but nothing happens. Logs show 200 OK but the feature doesn't work. This guide gives you a systematic approach for diagnosing and fixing webhook
Platform Engineering
Platform engineering teams need their own measurement framework — not just the DORA metrics they report for product teams. This guide covers the KPIs that matter for IDP reliability: golden path success rates, self-service workflow latency, platform API availability, test coverage breadth, and how to connect testing metrics to business outcomes.
AI Testing
AI-powered E2E testing matured significantly in 2025–2026. Playwright Agents, Playwright MCP, and a generation of AI-native platforms have moved the category from demo-ware to production-ready tools. This post maps where the category actually stands: what works, what still fails, and what the next frontier looks like. Key Takeaways Selector

Reflect.run is a popular no-code browser testing tool built around a simple visual recorder. Teams that evaluate or use Reflect.run frequently compare it to HelpMeTest — here's a direct comparison of how the two approaches differ in practice. What Reflect.run Offers Reflect.run's core
