Codeceptjs Docker

CodeceptJS has an official docker image based on Playwright image. Image supports Playwright, Puppeteer, and WebDriver engines.

How to Use

This image comes with the necessary dependencies and packages to execute CodeceptJS tests. Mount in your CodeceptJS config directory into the /tests directory in the docker container.

Sample mount: -v path/to/codecept.conf.js:/tests

CodeceptJS runner is available inside container as codeceptjs.

Locally

You can execute CodeceptJS with Puppeteer locally with no extra configuration.

docker run --net=host -v $PWD:/tests codeceptjs/codeceptjs

To customize execution call codeceptjs command:

# run tests with steps
docker run --net=host -v $PWD:/tests codeceptjs/codeceptjs codeceptjs run --steps

# run tests with @user in a name
docker run --net=host -v $PWD:/tests codeceptjs/codeceptjs codeceptjs run --grep "@user"

Docker Compose

version: '2'
services:
  codeceptjs:
    image: codeceptjs/codeceptjs
    depends_on:
      - web
    volumes:
      - .:/tests
  web:
    image: node
    command: node app/server.js
    volumes:
      - .:/app

The official image bundles browsers, and WebdriverIO 9 starts the matching driver automatically — no separate Selenium container or container linking is required for the WebDriver engine.

Note: The output of your test run will appear in your local directory if your output path is ./output in the CodeceptJS config

Build

To build this image:

docker build -t codeceptjs/codeceptjs .

• this directory will be added as /codecept insde container
• tests directory is expected to be mounted as /tests
• codeceptjs is a synlink to /codecept/bin/codecept.js

To build this image with your desired Node version:

docker build -t codeceptjs/codeceptjs . --build-arg NODE_VERSION=12.10.0

Passing Options

Options can be passed by calling codeceptjs:

docker run -v $PWD:/tests codeceptjs/codeceptjs codeceptjs run --debug

Alternatively arguments to codecept run command can be passed via CODECEPT_ARGS environment variable. For example to run your tests with debug output:

version: '2'
services:
  codeceptjs:
    image: codeceptjs/codeceptjs
    environment:
      - CODECEPT_ARGS=--debug
    volumes:
      - .:/tests

You can also use run-workersto run tests by passing NO_OF_WORKERS, additionally, you can pass more params like showing the debug info as the following example:

version: '2'
services:
  codeceptjs:
    image: codeceptjs/codeceptjs
    environment:
      - NO_OF_WORKERS=3
      - CODECEPT_ARGS=--debug
    volumes:
      - .:/tests
