常见问题

Quick answers.

Does this tool execute my code?

No. This is a boilerplate generator that produces string templates based on your input; it does not import or run your JavaScript files.

What testing patterns does it use?

It uses the standard BDD (Behaviour-Driven Development) style with `describe` for grouping and `it` for individual test cases.

Can I add more assertions later?

Yes. The tool provides the structural scaffold; you will need to add your specific `expect()` assertions once you paste the code into your IDE.

Is my code sent to a server?

No. Like all our developer tools, the generation logic runs entirely in your browser and never transmits your function names or component logic.
