Test data management is one of the most neglected parts of a test suite. Tests that rely on a specific database state are brittle. Tests that build every object from scratch are verbose and hard to read. Getting it right — using the right tool for each scenario — makes your tests
Testing
Running Browserless yourself means you control everything: concurrency, memory, network, and cost. The Docker image packages Chrome, all its dependencies, and the Browserless API layer into a single container. Here's how to get it running and configured for real use. Pulling the Image Browserless v2 uses ghcr.io/
Testing
Code coverage tells you which lines were executed during tests. It says nothing about whether those tests actually verify anything. A test that calls every function but makes no assertions gets 100% code coverage. Mutation testing fixes this. Infection, the PHP mutation testing framework, modifies your code in small ways
Testing
End-to-end testing browser extensions is significantly more complex than E2E testing a web app. Extensions have multiple entry points (popup, options page, content scripts, service worker), interact with browser APIs that automation tools don't fully support, and have permission models that affect behavior. This guide covers
Testing
Content scripts are the part of a browser extension that runs in the context of web pages — modifying the DOM, reading page content, and communicating with the background script. They're often the most complex part of an extension to test because they combine DOM manipulation with the browser
PHP
Unit tests with mocks are fast and isolated, but they don't catch the class of bugs that only appear when real SQL runs against a real schema — constraint violations, wrong joins, missing indexes, transaction rollbacks that don't behave as expected. Integration testing with real databases finds
Code Coverage
Coverage tools report four or five different metrics, and most teams pick one number to track without fully understanding what the others measure. That's a problem because each metric catches different categories of untested code, and conflating them gives you false confidence. This is the complete breakdown. Statement
PHP
Code coverage tells you which lines your tests execute. Mutation testing tells you whether your tests actually catch bugs. These are very different things — and the gap between them is where silent regressions live. Infection is the leading mutation testing framework for PHP. It works by making small, deliberate changes
PHP
Architecture decisions decay silently. A developer in a hurry imports a database model directly into a controller action. Another adds a framework dependency to a domain class. Each violation seems small, but they compound into a codebase where "clean architecture" is a historical fiction. Architecture testing tools make
PHP
When your PHP application talks to external APIs — payment gateways, shipping providers, weather services, anything — your tests shouldn't actually call those APIs. Real HTTP calls are slow, flaky, rate-limited, and costly. Worse, they make your test suite dependent on external uptime. Guzzle, the most widely used PHP

```tldr Bootloader testing covers three areas: unit testing the bootloader's logic (image validation, signature verification, boot selection), integration testing in QEMU (does the bootloader actually boot the right image?), and end-to-end OTA testing (does an update succeed, and does rollback work when the new image fails?
Laravel
Pest PHP goes far beyond basic test syntax. This post explores higher-order tests, custom expectations, datasets, lifecycle hooks, and parallel test execution — the patterns that make large Laravel test suites fast and maintainable. Pest PHP has become the default testing framework for many Laravel teams, not just because of
