FAQPage Schema

How do I set up unit testing and e2e testing in an Epic Stack application?▼

To set up Epic Stack testing, use Vitest for unit testing component logic and Playwright for end-to-end testing user workflows, forms, and routes. This combination ensures robust coverage for individual utilities and complete user journeys.

How do I test authenticated routes and user workflows with Playwright in the Epic Stack?▼

Testing authenticated routes in the Epic Stack involves using Playwright fixtures for authentication and navigation. You set up test database interactions and permission checks to simulate complete user journeys from signup to data submission securely.

What is the best way to mock external services and APIs during Epic Stack testing?▼

The best way to mock external services during Epic Stack testing is by using Mock Service Worker (MSW). MSW allows you to intercept network requests and simulate API responses, ensuring your unit and e2e tests remain isolated and reliable.

How do I test Remix loaders and actions in my Epic Stack project?▼

Testing Remix loaders and actions in an Epic Stack project requires writing Vitest unit tests that validate form submissions and data fetching logic. You manage test databases and mock API interactions to verify loader and action behavior accurately.

Does Epic Stack testing support validating form submissions and permission checks?▼

Yes, Epic Stack testing supports validating form submissions and permission checks. You can write Vitest unit tests for form validation logic and use Playwright to verify end-to-end permission enforcement across different user roles and routes.
