When working on my test file, I utilize a folder named mocks which contains various exported functions. Most of the time, I rely on the mocks folder to perform all necessary tasks. However, there is one scenario where I need to adjust the return value to accommodate another function. Unfortunately, I am unsure how to revert back to the original/default mock.
Consider the following example:
// __mocks__/user.ts
export default someModuleFunction = () => {
return 'default mock'
}
// user.test.ts
import {someModuleFunction} from 'user';
jest.mock('../users')
describe("TestFile", () => {
it("should mock the return value in here", () => {
(someModuleFunction as jest.Mock) = jest.fn().mockReturnValue(null)
expect(someModuleFunction).toEqual(null)
})
it("should fallback to the original default mock", async() => {
expect(someModuleFunction).toEqual('default mock')
})
})
