I'm trying to unit test a function that returns a promise. I'm having challenges verifying if
the mocked functions are called. Here's what I've done.,

// codetotest.js

const { SomeModule, isSomething, isSomethingElse } = require("some-module");



exports.somefunction = (param1, param2)=> {

    const someModule = new SomeModule();



    someModule.someMethod("aaa", isSomething);

    someModule.someMethod("bbb", isSomethingElse);



    return (someModule.someOtherMethod(param1)

    .then(()=>{someModule.run(param2)}));

}

And this is the test file, the test says the mocked functions are not called, but I do see the console statement in the mock function is being displayed.

// codetotest.test.js

const { somefunction} = require("./codetotest.js");

const { SomeModule } = require("some-module");



jest.mock("some-module", () => {

    return {

        SomeModule: jest.fn().mockImplementation(() => {

            return {

                someMethod: jest.fn((param, fn) => { console.log("This prints!"); }),

                someOtherMethod: jest.fn((param) => { return Promise.resolve(() => { }) }),

                run: jest.fn((param) => { return Promise.resolve(() => { return []; }) })

            }

        })

    };

});



afterEach(() => {

    jest.resetAllMocks();

    jest.restoreAllMocks();

});



describe("Test codetotest.js", () => {

    it("somefunction() - success", async () => {

        const someModule = new SomeModule();



        let output = await somefunction("param1", "param2");



        expect(SomeModule).toHaveBeenCalled();

        expect(someModule.someMethod).toHaveBeenCalled(); // This fails



        await expect(someModule.someOtherMethod.mock.results[0]).resolves;

        expect(someModule.someOtherMethod).toHaveBeenCalled(); // This fails



        await expect(someModule.run.mocks.results[0]).resolves;

        expect(someModule.run).toHaveBeenCalled(); // This fails

    });

});

Appreciate any help/pointers.

Thank you.

P.S: I'm still a beginner when it comes to nodeJs development and unit testing.
