Inspecting (Compatible with Jest Snapshots)

const { mock, inspect } = require("mockital");

const Mock = mock();

Mock.a = "is this is amazing?";

const wow = new Mock.b.c["c"](1, "2", [1, 2]);

wow.d.e(1, 2, 3).f = "this is amazing";

// Jest
expect(inspect(Mock)).toMatchSnapshot();

JSON.stringify(inspect(Mock)) ===

Reset mock

const { mock, reset, inspect } = require("mockital");

const Mock = mock();

Mock.a.b.c("1", "2", "3");

reset(Mock);

JSON.stringify(inspect(Mock)) === [];

Stubbing values

const { mock, when } = require("mockital");

const Mock = mock();

when("a", mock().a.b.c("1", "2", "3"), Mock);

Mock.a.b.c("1", "2", "3") === "a";

Reset stubbed values

const { mock, resetWhen, when } = require("mockital");

const Mock = mock();

when("a", mock().a.b.c("1", "2", "3"), Mock);

resetWhen(Mock);

// stubbed value no longer returned
Mock.a.b.c("1", "2", "3").d.e;
