FAQPage Schema
How do I write unit tests for iii functions using Vitest?

To write unit tests for iii functions using Vitest, you can mock the iii-sdk and test your function handlers directly with mock contexts. This approach verifies handler behavior under various input conditions while isolating the iii engine's state and triggers.

What is the best way to mock the iii-sdk for integration testing?

Mocking the iii-sdk for integration testing involves creating mock implementations to isolate your functions. This allows you to validate handler behavior with Vitest, ensuring deterministic testing of asynchronous operations and complex state management within the iii ecosystem.

Can I test asynchronous operations and state management in Motia steps?

Yes, you can test asynchronous operations and state management in Motia steps. By structuring test suites and setting up test fixtures, this Skill validates handler behavior and ensures deterministic testing of complex state interactions within your iii ecosystem.

Does this approach support testing triggers and workers with mock contexts?

Testing triggers and workers with mock contexts is fully supported. The Skill generates test files and structures test suites that enable direct testing of function and step handlers, validating interactions with the iii engine's state and triggers.

Why do I need to mock the init() function when testing iii functions?

You need to mock the init() function to isolate your iii functions for unit testing. Mocking the iii-sdk init() function ensures deterministic testing by preventing actual side effects, allowing you to verify handler behavior under controlled input conditions.
