How to mock module function using proxyquire

Question

I need to mock 'mkdirp-promise' node module which exposes a constructor function as below

mkdirpPromise(dirPath)
        .then(() => {
            console.log('ABCDEFGH');
            resolve(dirPath);
        })
        .catch((error) => {
            console.log('HeABCDEFGHre');
            const details = error.message;
            const err = customError.failed_create_downloads_directory()
                .withDetails(details);
            reject(err);
        });

Im able to mock it using proxiquire as below for the first time:-

let mkdirpPromiseMock = sinon.stub().rejects();

 const sthreeDownloadMock =
    proxyquire('./../../modules/sThreeDownload', {
        joi: joiMock,
        fs: fsMock,
        '@monotype/core-error': {
            errors: {
                ApiError: customErrorMock,
            },
        },
        'aws-sdk': awsSDK,
        'mkdirp-promise': mkdirpPromiseMock,
        path: pathMock,
    });

Now i want to override mkdirpPromiseMock in 2nd test case with

mkdirpPromiseMock = sinon.stub().resolves();

which im not able to. Any help is appreciated.

That should have worked fine, but "which im not able to" is not really providing any details with which we could help you. A simplified case that is runnable and shows the problem would help — oligofren, Mar 28 '18 at 14:01

Proxyquire is not compatible with jest.

You need to use a mocking library like rewiremock.

Please have a look at this answer which goes into detail.
