Package Exports

mockital

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (mockital) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

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();

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;
