Preview

Basic input/output example:

Usage

Installation

run npm i -g jest-test-gen

Basic Usage

run jest-test-gen <path-to-file>

TODO

• Custom test output for React components
• Enhance jest.mock support
• TS unit test output for Typescript sources

Development

It's probably best to:

• add an input file in spec/fixtures folder test.js
• add expected output file, e.g. expected.test.js
• link them in integration.spec.ts

Alternavely, you can:

• run npm link
• run npm run build:dev
• run jest-test-gen <option> in your project of choice

Release

run npm run build run npm publish
