Hexcore Mocker

Package moved to https://www.npmjs.com/package/@hexancore/mocker

Mocker package is super simple wrapper for Jest mocks util with extra stuff :).

Usage

import { Mocker } from '@hexcore/mocker';

interface TestMock {
  a(param1: string, param2: boolean): boolean;
  b(param1: string, param2: boolean): boolean;
}

// you can simply mock interface or class and give it descriptive name(used in errors)
const mock = Mocker.of<TestMock>("test_mock");

// define method call expectation(available methods list will be shows in VS)
mock.expects('a', 'test', true).andReturn(true);

// mock "i" attribute is object of mocked class, pass it where you need
mock.i.a('test', true);

// after execute your code, you can check sets expectations results with it(for many tests call it in jest "afterEach")
mock.checkExpections();

Defining expectation

Mocker::expects(method, ...args) returns MethodMock object with you can define return value by:

• andReturnWith((implementation: (...args: any) => any) - you can define your own method implementation
• andReturn(value: any) - define returns passed value once
• andReturnResolved - simple sugar function for andReturnWith((() => Promise.resolve(value))
