proxy-mock-js v1.0.3

proxy-mock

A mock that can be used for anything

Recursively creates properties on demand(they are created as new copy of proxy-mock), can be called as function, supports toPrimitive and iterator methods.

Install

$ npm install proxy-mock-js

Use

const mock = getProxyMock();
const { a, b, c} = mock; // a, b, c will be new proxy-mock copies
const nested = mock.db.users[3].address.street; // will work, all the keys will be created as new proxy-mock copies
const fnResult = mock.get('/cats'); // will result in yet another proxy-mock copy
const math = mock * 2; // will result in 84, since in case of toPrimitive calls we return primitive value, in this case it's 42

auto spy(jasmine example)

proxy mock supports auto spying on newly created properties, you just have to pass the the spy function to proxy-mock

const spyFn = (name, fn) => {
    return jasmine.createSpy(name, fn).and.callThrough();
}
const mock = getProxyMock({}, 'httpClient', spyFn);
mock.post('/api/call');
expect(mock.post).toHaveBeenCalled();

spyFn will be called each time new proxy is created and target will get neatly wrapped by the spy
