Testcases are failing from 1.5.7

[sureshacct]

Hello

I am using react-testing-library to test my network components and it was working fine until 1.5.6 version. After upgrading to 1.5.7 I am observing failures

Sample testcase:

it('fetches resource and returns proper data on success', async () => {
        const id = '12345';
        const type = 'text';
        const fetchFunction: () => Promise<QueryResponse> = async () => ({
            error: false,
            status: 200,
            payload: successResponse,
        });
        const Client = createClient({
            params: { host: 'https://mockHost', basePath: 'mockPath', defaultQueryParams: {} },
        });
        Client.query = fetchFunction;

        const wrapper = ({ children }: any): any => (
            <ClientContextProvider client={Client}>{children}</ClientContextProvider>
        );

        jest.useFakeTimers();

        const { result } = renderHook<void, any>(
            () => useFetchQuery(id, type),
            {
                wrapper: wrapper,
            },
        );
        expect(result.current.loading).toEqual(true);
        expect(result.current.error).toEqual(false);
        act(() => {
            jest.runAllTimers();
        });

        expect(result.current.loading).toEqual(false);
        expect(result.current.error).toEqual(false);     
    });

Issue: Looks like there is some issue with the request interceptor. There is null response from interceptor

I am stuck with 1.5.6 release but i have to upgrade it to latest version to use some of its features

Hi @sureshacct

I can't see any interceptors here, could you provide an example in codesandbox?

Hi @marcin-piela

I have added a sample project in the below codesandbox.
https://codesandbox.io/s/agitated-shaw-jcw63

Added a hook useFetchResource.ts and its associated test file along with interceptor. The test passes until 1.5.6 version but post that its failing.
