Using SWRConfig + cache in swr@beta for tests

[Naddiseo]

With the new cacheProvider in swr@beta, the documentation says "createCache should not be called inside render, it should be a global singleton.", so my question is if I'm using the <SWRConfig> approach, how do I clear the cache between tests? The documented approach requires that I call useSwr directly in the test or pass cache down to it, however, that's not feasible in practice.

With [email protected] I'm currently using a wrapper function with testing-library and a custom render function:

import { render } from "@testing-library/react";
import { cache, SWRConfig } from "swr";

const wrapper = ({children})=> (<SWRConfig value={{ dedupingInterval:  0 }}>{children}</SWRConfig>);
const customRender = (ui, options={}) => render(ui, { wrapper, ...options});

afterEach(() => { cache.clear();} );
export {customRender as render};

Would the best approach be to create the cache in the customRender function and pass it into the wrapper, like the following?

import { render } from "@testing-library/react";
import { createCache, SWRConfig } from "swr";

const wrapper = (cache, {children})=> (<SWRConfig value={{ dedupingInterval:  0, cache }}>{children}</SWRConfig>);
const customRender = (ui, options={}) => {
  const { cache } = createCache(new Map());
  return render(ui, { wrapper.bind(null, cache), ...options});
};

export {customRender as render};
