Testing
AI is changing software testing at every level: unit test generation, selector healing, visual regression detection, and natural language test authoring. The changes shift the QA engineer's job from writing tests to reviewing, orchestrating, and improving AI-generated tests. The teams most ahead are using AI to expand test
Integration Testing
Integration tests verify that PHP components work together: your service classes with a real database, your HTTP controllers with real routing, your external API clients against real or stubbed endpoints. This guide covers database integration testing with transactions, HTTP layer testing, testing with real queues and caches, and integrating with
Testing
AI can generate realistic, varied test data faster than manual creation or factory libraries. The key is prompting for diversity and edge cases, not just valid examples. This guide covers practical patterns for using LLMs to generate test data across formats — JSON fixtures, database seeds, CSV files, and domain-specific data
Tools & Frameworks
Mockery is PHP's most powerful mocking library, popular in Laravel and Symfony ecosystems. It provides a fluent API for creating test doubles: mocks, stubs, spies, and partial mocks. This guide covers creating mocks, defining expectations with shouldReceive, argument matchers, mock verification, spies, and using Mockery with PHPUnit and
Testing
The AI testing tools landscape in 2025 covers unit test generation, end-to-end test automation, and AI-assisted debugging. The tools don't compete directly — they solve different problems. Qodo (formerly CodiumAI) focuses on unit test generation with iteration until tests pass. GitHub Copilot accelerates inline test writing. Diffblue automates Java
Tools & Frameworks
Pest is a modern PHP testing framework built on top of PHPUnit. It offers a simpler, more expressive syntax with test(), it(), and expect() — inspired by Jest and RSpec. Pest is Laravel's default testing framework since Laravel 11. This guide covers setup, writing tests, datasets, architecture testing, and
Testing
GitHub Copilot can dramatically accelerate test writing when used correctly. The key is guiding it with context: write the first test yourself, name your test functions descriptively, and place the cursor strategically. Copilot does best at boilerplate and structure — you supply the domain knowledge and critical judgment. Key Takeaways Write
Tools & Frameworks
Laravel ships with a complete testing setup: PHPUnit configured, database factories, HTTP test helpers, and Artisan commands to generate tests. Feature tests let you make real HTTP requests to your application without a running server. This guide covers unit tests, feature tests, database testing, facade mocking, queue/event faking, and
Testing
Large language models can generate unit tests from source code, docstrings, or natural language descriptions. They excel at happy-path tests and boilerplate reduction but miss edge cases without explicit prompting. This guide explains how LLM-based test generation works, which tools use it, and how to integrate it into a real
Tools & Frameworks
PHPUnit is the standard testing framework for PHP. Every major PHP framework — Laravel, Symfony, WordPress — uses or supports PHPUnit. This guide covers installation, writing test classes, assertions, test doubles (mocks, stubs, spies), data providers, exception testing, code coverage, and CI integration. Key Takeaways PHPUnit test classes extend TestCase and methods
Developers
Every time you change a prompt, update a model, or adjust your context injection logic, you risk a silent regression — the LLM starts producing subtly different outputs that break downstream behavior. Without CI tests for your prompts, you find these regressions in production from user complaints. This guide shows how

The Composable Architecture (TCA) from Point-Free is a Swift state management library for building apps in a Redux-style unidirectional data flow. One of TCA's selling points is testability: TestStore makes it straightforward to test state mutations, action sequences, and effects. TCA in 30 Seconds A TCA feature consists
