Using along with Jest

[budziam]

Decorating the method with @boundMethod decorator causes that Jest creates incorrect mocked object based on class definition.

Example code

import { boundMethod } from "autobind-decorator";
import jestMock from "jest-mock";

class Abc {
    @boundMethod
    foo() {
        //
    }

    bar() {
        //
    }
}

const Mock = jestMock.generateFromMetadata(jestMock.getMetadata(Abc));
const obj = new Mock();
console.log(Object.keys(obj)); // === ["bar"]

The problem is that the object obj doesn't have the foo method.

The way how to create mocked object instance is taken from this library: https://www.npmjs.com/package/jest-create-mock-instance

Does #79 or #57 work for you?

None of those solve my issue

Still an issue as of today: when using something like

jest.spyOn(instance, "myHandler");

Where myHandler is a boundMethod in my class component that I'm trying to test, test gives the following error:

TypeError: object[methodName].mockImplementation is not a function

Any updates on this? Has anyone solved this?
