Setup

Install With NPM

npm i -D mockzilla

Install With Yarn

yarn add --dev mockzilla

Jest

Aside from mockzilla itself, you'll only need jest (opens new window).

Here's a quick setup guide for jest with TypeScript: (you can skip this if you are already using jest with TypeScript)

Install with NPM

npm i -D jest @types/jest ts-jest

Or with Yarn:

yarn add --dev jest @types/jest ts-jest

Create a file jest.config.js:

module.exports = {
    transform: {
        ".+\\.ts$": "ts-jest",
    },
    testRegex: "(/__tests__/.*|(\\.|/)(test|spec))\\.ts$",
    moduleFileExtensions: ["ts", "js"],
};

add a test script to your package.json:

  "scripts": {
    ...
    "test": "jest"
  }

Now all you need to do is write test files and run the tests with NPM:

npm t

Or with Yarn:

yarn test
