    jest-electron

    Easiest way to run jest unit test cases in electron.

    When we run unit test in Jest, it is actually running in the node environment, or virtual browser environment(e.g. JSDOM) mocked by NodeJS. Sometimes we need a lot of Jest mocks for running code with no throw, such as: jest-canvas-mock, jest-storage-mock, @jest/fake-timers and so on. This is solved by Jest-Electron.

    Build Status npm npm

    1. Technological ecology of Jest.
    2. Complete and real browser environment.
    3. Multi-renderer for running performance.
    4. Running and debug is better then mock.

    Installation

    • Add into devDependencies
    $ npm i --save-dev jest-electron
    • Update Jest config
    {
      "jest": {
    +    "runner": "jest-electron/runner",
    +    "testEnvironment": "jest-electron/environment"
      }
    }

    Notice: update the runner configure, not testRunner.

    • travis

    Update .travis.yml with electron supported.

    language: node_js
    node_js:
      - "8"
      - "9"
      - "10"
      - "11"

    +   - npm install
    script:
      - npm run test

    Depending on your executor, you might need to disable sandbox and shared memory usage:

    export JEST_ELECTRON_STARTUP_ARGS='--disable-dev-shm-usage --no-sandbox'
    npm run test

    Env

    • debug mode

    Keep the electron browser window for debugging, set process env DEBUG_MODE=1.

    DEBUG_MODE=1 jest
    • additional startup arguments

    Run electron with arbitrary arguments.

    JEST_ELECTRON_STARTUP_ARGS='--disable-dev-shm-usage'

    Run electron with --no-sandbox, set process env JEST_ELECTRON_STARTUP_ARGS='--no-sandbox'.

    JEST_ELECTRON_STARTUP_ARGS='--no-sandbox' jest
