CodeceptJS Sample How-To

This project was used by me (Gaston) while ramping-up on CodeceptJS. These are my notes, so no warranty is provided.

Goals:

• Quickly ramp-up on CodeceptJS
• Create a simple, yet useful test (i.e. log into Peregrine)
• Run tests locally
• Run tests on Docker
• Record test run

Run Tests Locally

1. Run tests on your machine.

$ ./local-run.sh

or

$ npm run test

Record Tests with Docker

1. Build the Docker image (or pull it from DockerHub).

$ ./docker-build.sh

2. Run the tests and capture video.

$ ./docker-run.sh

or

$ npm run docker-test

How This Project Was Created

This project was bootstrapped using the following instructions.

1. Create a workspace.

$ mkdir codeceptjs-explore && cd codeceptjs-explore

2. Install CodeceptJS and Puppeteer.

$ npm init -y
$ npm install codeceptjs puppeteer --save-dev

3. Create a CodeceptJS project.

$ npx codeceptjs init

All the defaults were used, except for these changes:

• What helpers do you want to use?: Puppeteer
• [Puppeteer] Base url of site to be tested: http://localhost:8080
• Feature which is being tested: Peregrine Login

4. Start Peregrine locally in another terminal.

5. Edit login_test.js.

Feature('login');
  
Scenario('Log into Peregrine', (I) => {
  I.amOnPage('/');
  I.see('Log In');
  I.fillField('Username', 'admin');
  I.fillField('Password', 'admin');
  I.click('Log In');
  I.see('your websites');
});

6. To run tests on your machine with Docker, add --no-sandbox argument to codecept.conf.js. See issues/1022.

Puppeteer: {
...
    chrome: {
        ...
        args: ['--no-sandbox']
    }
}
