Integration Testing
Mocking database calls in Python tests creates a false sense of security. testcontainers-python spins up real PostgreSQL, Redis, and MongoDB containers via Docker during your pytest run, giving you genuine integration coverage without managing external services. Key Takeaways testcontainers-python integrates with pytest through fixtures. Define containers in conftest.py and
Integration Testing
Node.js integration tests that mock PostgreSQL and Redis test your assumptions, not your code. testcontainers starts real database containers during your Jest run and tears them down after. Your tests talk to the actual services — no mocks, no drift, no surprises. Key Takeaways testcontainers/node works with Jest, Vitest,
Docker
Shipping a Docker image without testing it is like deploying code without tests — the problems show up in production. Docker containers need their own testing layer: build tests, container smoke tests, integration tests, and security scans. Here's how to build that layer. Key Takeaways Test at four levels:
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
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
Integration Testing
Integration testing in .NET means testing your application with real dependencies — real HTTP routing, real database queries, real middleware. WebApplicationFactory from Microsoft.AspNetCore.Mvc.Testing spins up your actual ASP.NET Core app in memory, letting you send real HTTP requests without a running server. This guide covers setup, database
