renderHook support for multiple parameters
Describe the feature you'd like:
Testing hooks should support hooks with multiple parameters. Currently, the option "initialProps" of renderHook, and the "rerender" function it returns are supporting only a single parameter.
Suggested implementation:
Obviously, for backwards compatibility, the option "initialProps" cannot be changed. Therefore, I suggest to add a new option "initialArgs" that is an array and renders the hook to be tested by spreading that array.
The function "rerender" returned from "renderHook" will take multiple parameters and forward them to the hook as well.
import useHook from "..."
const { result, rerender } = renderHook(useHook, { initialArgs: [1, 2, 3] })
rerender(3, 4, 5)
It should be an error (exception) to pass both options "initialProps" and "initialArgs" at the same time.
Describe alternatives you've considered:
As a workaround, I currently wrap my multi-arg hooks in a wrapper hook taking an array as "props", but that is cumbersome:
import useHook from "..."
function useTestHook(args) {
return useHook(...args)
}
const { result, rerender } = renderHook(useTestHook, { initialProps: [1, 2, 3] })
rerender([3, 4, 5])
