            How to force a return value from a mocked non-exported function using sinon or proxyquire or rewire?
            Asked 2022-Feb-28 at 03:19

            I am just getting started unit testing nodejs. I have been using mocha, chai and sinon.

            I hit a snag when I wanted to test a function which is not exported. proxyquire looks good, as does rewire.

            There are lots of tutorials, but they tend to be simplistic. E.g

            AWS is a namespace, it contains all AWS service classes like SecretsManager. You should provide the awsStub to aws-sdk, there is no need to wrap the awsStub inside an object.

            You don't need to use proxyquire package, use sinon.stub(obj, 'method') to stub methods of object. You can stub fs.mkdir, unzipper.Extract and fs.createReadStream methods.

            You use util.promisify to convert fs.mkdir into a promise form and call it, but underly is still the callback being called, so you need to use the .callsFake() method to mock implementation for fs.mkdir, and call the callback manually in the test case.

            The below example uses mocha as testing framework, but ava should also be fine.

            Since the RMQ_INSTANCE is an object, you can stub its methods using sinon.stub(obj, 'method'), you don't need to use proxyquire package.

            Since you want to test the b module, the b module only cares about the interface of the RMQ_INSTANCE it depends on, and the specific implementation does not matter.

            ANSWER

            Answered 2021-Jul-15 at 18:20

            Spying involves replacing the function with a new function. You are replacing what is referred to by the identifier functionIWantToSpy so that it refers to a new spy function, instead of the original function referred to by require('@mycompany/another-lib').functionIWantToSpy. The code inside the module can't see your new spy function. The expression require('@mycompany/another-lib').functionIWantToSpy refers to the original function, unchanged.

            Because require caches results (i.e., only the first require("foo") executes foo, and any subsequent require("foo") summons up that same object returned by the first require call), you can modify the functionIWantToSpy method of the require('@mycompany/another-lib') object, using the two-argument form of sinon.spy:
