Introduction

This package is a temporary stand-in for Jest, which doesn't currently support ES modules (I think).

Installation

npm install --save-dev @jrc03c/fake-jest

Usage

Step 1: Write a test file:

// my-cool-function.test.mjs
import { afterAll, beforeAll, expect, test } from "./index.mjs"
import { myCoolFunction } from "./my-cool-function.mjs"

beforeAll(() => {
  // set up
})

afterAll(() => {
  // tear down
})

test("that `myCoolFunction` works as expected", () => {
  expect(() => myCoolFunction()).not.toThrow()
})

Step 2a: Run the tests in my-cool-function.test.mjs by running it as a normal Node script:

node path/to/my-cool-function.test.mjs

...or by invoking the fake-jest executable and passing the path as an argument:

npx fake-jest path/to/my-cool-function.test.mjs

Step 2b: To run all tests in a project, invoke the fake-jest executable with no arguments:

npx fake-jest
