API

This documentation covers the specifics of these bindings. To learn about the principles and approach behind Testing Library, refer to the official documentation.

All methods from @testing-library/react-hooks-testing-library are implemented. Values that are returned from renderHook in the original JavaScript version have getter methods equivalents in there bindings. For example, the JavaScript method to retrieve a hooks current value is:

const { result } = renderHook(() => React.useState(1));
console.log(result.current) // logs "1"

The equalivent in these bindings is the current method:

const result = renderHook(() => React.useState(_ => 1));
Js.log(result |> current) // logs "1"

Review the interface file for the full API. Example tests are also available.
