To write unit tests for server actions using Jest, you target specific server action files and create test files to verify their individual functions and logic. This ensures your server actions work correctly in isolation before integration.

Yes, you can use Playwright for E2E testing in a Multi-Vendor EC project to automate and verify user journeys. It validates complete user flows, such as navigating from product creation to display, ensuring application robustness.

The best way to ensure test coverage for new e-commerce features is by combining Jest unit tests for server actions with Playwright E2E tests for user flows. This dual approach verifies both backend logic and frontend interactions.

Yes, this testing approach handles test data seeding and colocation by adhering to testing best practices. It ensures tests are located near the code they verify and manages the necessary data setup for reliable execution.

To modify existing tests when adding new product listing capabilities, you update the Jest unit tests for the modified server actions and adjust Playwright E2E tests to cover the updated user flow from product creation to display.
