Jest mock module multiple times with different values

Question

I have a function that I want to test and this function uses an imported module:

var a = require(\'./a\');

function add(b) {
  return a + b;
}

module.expor         


        

Answer 1

Add

beforeEach(() => {
    jest.resetModules();
});

Final tests

describe('add', () => {

    beforeEach(() => {
        jest.resetModules();
    });

    it('should add the mock number 5 to 2', () => {
        jest.setMock('./a', 5);
        const add = require('./add');
        expect(add(2)).toBe(7);
    });

    it('should add the mock number 2 to 2', () => {
        jest.setMock('./a', 2);
        const add = require('./add');
        expect(add(2)).toBe(4);
    });
});
