The approach uses Copilot to draft test skeletons and Testcontainers to spin up real database dependencies, enabling faster and more reliable testing. The workflow is designed to integrate into CI/CD pipelines, allowing developers to build and ship with greater confidence.", "body_md": "**Introduction**\n\nModern development isn’t just about writing code—it’s about writing **better code, faster**. With AI-assisted tools like **GitHub Copilot** and infrastructure helpers like **Testcontainers**, developers can move from idea to production-ready systems at lightning speed.\n\n**The Problem**\n\n**The Solution: AI + Containers**\n\nBy combining **GitHub Copilot** for code generation and **Testcontainers** for integration testing, you can accelerate development while maintaining confidence in your systems.\n\n**Step 1: Let Copilot Draft Your Test**\n\nCopilot can generate the skeleton of your integration test:\n\n```\n[Fact]\npublic async Task ShouldSaveAndRetrieveLead()\n{\n    // Copilot suggests setup, assertions, and cleanup\n}\n```\n\n**Step 2: Add Real Dependencies with Testcontainers**\n\n``` js\nvar sqlContainer = new MsSqlBuilder().Build();\nawait sqlContainer.StartAsync();\n\nusing var conn = new SqlConnection(sqlContainer.GetConnectionString());\nawait conn.OpenAsync();\n\n// Run schema + insert test data\n```\n\n**Step 3: Automate in CI/CD**\n\n**Why This Matters**\n\n**Closing Thought**\n\nAI isn’t replacing developers—it’s augmenting them. By pairing Copilot’s intelligence with Testcontainers’ reliability, you can build faster, test smarter, and ship with confidence.", "url": "https://wpnews.pro/news/supercharging-net-development-with-github-copilot-and-testcontainers", "canonical_source": "https://dev.to/printo_tom/supercharging-net-development-with-github-copilot-and-testcontainers-4ml6", "published_at": "2026-07-09 17:12:50+00:00", "updated_at": "2026-07-09 17:35:50.388046+00:00", "lang": "en", "topics": ["developer-tools", "artificial-intelligence", "ai-tools"], "entities": ["GitHub Copilot", "Testcontainers", ".NET"], "alternates": {"html": "https://wpnews.pro/news/supercharging-net-development-with-github-copilot-and-testcontainers", "markdown": "https://wpnews.pro/news/supercharging-net-development-with-github-copilot-and-testcontainers.md", "text": "https://wpnews.pro/news/supercharging-net-development-with-github-copilot-and-testcontainers.txt", "jsonld": "https://wpnews.pro/news/supercharging-net-development-with-github-copilot-and-testcontainers.jsonld"}}
