What is Magnitude?
Is maintaining your web application's end-to-end tests becoming a constant battle against minor UI changes? Magnitude offers a fresh approach. It's an open-source, AI-native testing framework designed specifically for modern web apps. Instead of relying on fragile DOM selectors, Magnitude employs visual AI agents that interact with your application just like a human user would—by looking at the screen. This allows you to build tests using simple natural language, resulting in more resilient, adaptable, and easier-to-maintain test suites.
Magnitude helps you ensure your application works as expected, focusing on user experience rather than implementation details. Let your tests adapt to UI changes, not break because of them.
How Magnitude Enhances Your Testing Workflow
Magnitude combines intelligent planning with precise visual execution to deliver reliable test results:
✍️ Build Tests with Natural Language: Describe your test steps, checks, and data requirements in plain English. Think of explaining the test flow to a colleague – Magnitude understands and executes it. This significantly lowers the barrier to creating comprehensive end-to-end tests.
👁️ Execute Reliably with Visual AI: Magnitude's executor agent (powered by the fast, open-source Moondream model) visually identifies elements and interacts with your web app. Because it doesn't depend on the underlying DOM structure, tests are far less likely to break due to code refactoring or minor UI adjustments.
🧠 Plan Intelligently with Advanced AI: A powerful planning LLM (like Gemini 2.5 Pro, Claude, or GPT-4o) interprets your natural language instructions, devises a robust test plan, and can even reason about unexpected situations or errors encountered during a test run, attempting to recover or providing insightful failure analysis.
📄 Ensure Consistent & Efficient Runs: The generated test plan is saved, ensuring that subsequent runs execute consistently. This predictability, combined with intelligent caching, makes test execution fast and cost-effective.
🛠️ Integrate Seamlessly into Your Workflow: Run Magnitude tests locally during development or integrate them directly into your CI/CD pipelines (like GitHub Actions). Magnitude installs as a dev dependency in your Node.js project, fitting naturally into existing processes.
See Magnitude in Action: Practical Scenarios
Testing a Frequently Updated E-commerce Checkout: Your team constantly tweaks the checkout flow for optimization. With traditional tools, tests break after nearly every update. Using Magnitude, you define steps like "add item to cart," "proceed to checkout," "enter shipping details," and "verify order summary." Magnitude's visual AI finds the correct buttons and fields even if their IDs, classes, or positions change, ensuring the core functionality remains validated.
Cross-Functional Team Collaboration: A product manager wants to define acceptance criteria for a new feature. They can write draft test cases in natural language using Magnitude's syntax (e.g.,
.step('navigate to user profile').check('should see the new avatar upload option')). The QA team can then refine and run these tests directly, improving collaboration and ensuring features meet business requirements from the start.Reducing Test Maintenance Overhead: A development team spends significant time fixing broken end-to-end tests after minor frontend refactors. By migrating to Magnitude, their tests become resilient to these changes. The visual AI adapts, reducing maintenance time and allowing the team to focus on building features rather than constantly repairing tests.
Get Started with Smarter Testing
Magnitude offers a more intuitive and robust way to conduct end-to-end testing for your web applications. By leveraging AI vision and natural language, it tackles the brittleness inherent in traditional testing methods, saving you time and effort while increasing confidence in your releases. As an open-source framework, it invites collaboration and transparency.
