Reality vs. requirements: How to align tests with real user behavior

Not long ago, the answer to who writes tests was simple: the quality assurance (QA) engineer does. They sat downstream of development, received a build, and translated requirements into scripts. It was a defined role with a defined output. That clarity is gone. In 2026, the person or system responsible for test creation might be a business analyst (BA) mapping out a customer journey, an AI agent expanding test coverage overnight, or a QA engineer who hasn’t written a traditional script in months.

Data Warehouse Design: A Complete 2026 Guide (with examples and templates)

Most data warehouse projects fail. Not because the technology is wrong. Because the design is. Three weeks for a number that should take three minutes. AI agents generating plausible reports nobody can trace. Two ERPs naming the same metric differently. The spreadsheet swamp. The fire drill before every audit. These problems live in the warehouse layer, in how data is modeled, governed, and made available to the people and AI agents that read from it.

From Traffic Context to Confirmed Fix in 3 Minutes

We’ve been building an AI agent that can take a production bug, find the root cause in captured traffic, write a fix, and validate it before a human reviews it. We call it Agent Factory. Last week we ran it on ourselves, against a real bug in our own production service. The first thing we did was get the workflow wrong.

Anatomy of the AI Software Factory: The Context Layer

This is Part 2 of the AI Software Factory series. In Part 1, we established that the Agile methodology is buckling under the weight of “elastic code.” When AI agents can generate functionality in seconds, two-week sprints and manual task management become organizational bottlenecks. We introduced the concept of the AI Software Factory: a shift from managing human tasks to managing business intent through a “Funnel of Increasing Trust.” But a factory requires infrastructure.

SwiftData Tutorial: Swift Data Storage for iOS Apps

Since its debut in June 2023, SwiftData has fundamentally changed how Apple developers approach persistence. Devs the world over love it for its versatility, its declarative ease and its powerful querying system. But if you’re new, SwiftData can take some getting used to. Failures can feel less transparent and relationships can play out differently to how you might expect. So in this tutorial we’ll show you how SwiftData works and how to.

The API testing gap: How AI-accelerated development challenges software quality

While AI accelerates development velocity by a factor of ten, a critical consequence remains: testing hasn’t kept pace. According to SmartBear research, 70% of software professionals report that their application quality has already degraded due to AI-accelerated development. Even more concerning, 60% have experienced quality issues in the past year as development velocity outstrips testing capacity.

Building an API Gateway with Koa and AppSignal

In an API-driven setup, a gateway often sits between clients and backend services: it can validate input, aggregate upstream responses, and give you one place to observe traffic. Koa is a strong fit for that role. Its core stays small, async/await is first-class, and middleware composes in a predictable stack. In this article, you will build a compact API gateway with Koa that: You will also wire up AppSignal for the Node.js stack.

Why Performance Testing Should Be a Priority for Mobile-First Businesses in 2026

Mobile-first businesses often enter the market confident in their app’s speed, but the reality is that many overestimate their performance – and pay for it through user churn and lost revenue. With 5.78 billion unique mobile users worldwide as of October 2025, representing 70.1% of the global population, the pressure to deliver a fast, reliable experience is immense.

Embedded Lending: The Rise of API-Driven Credit Platforms

Credit used to be a destination. You went to a bank, filled out forms, waited days, sometimes weeks, and hoped for approval. That model is quietly disappearing. Today, credit shows up exactly where you need it. While shopping online. While booking logistics. Even while managing business cash flow inside a SaaS dashboard. No redirects. No friction. No traditional loan journey. This shift is what we call Embedded Lending. It is not just a feature.
