Selenium/How-to/Create the first test in a repository

From mediawiki.org

This tutorial will assume that you are running tests from your machine, targeting MediaWiki-Docker.

For more examples see Selenium/Getting Started/Create a simple test page and Selenium/Reference/Example Code.

Let's write a new simple test for Extension:Examples. For example, let's check if the extension is listed at Special:Version page.

Simple

[edit]

The minimal amount of code is just one spec file and just one page object file.

tests/selenium/pageobjects/version.page.js

'use strict';

const Page = require( 'wdio-mediawiki/Page' );

// this is just a sample on how to create a page
class VersionPage extends Page {
  // this is just a sample on how to find an element
  get extension() {
    return $( '#mw-version-ext-other-examples' );
  }

  // this is just a sample on how to open a page
  async open() {
    return super.openTitle( 'Special:Version' );
  }
}

module.exports = new VersionPage();

tests/selenium/specs/version.js

'use strict';

const assert = require( 'assert' );
// this is just a sample on how to use a page
const VersionPage = require( '../pageobjects/version.page' );

describe( 'Examples', () => {

  // this is just a sample test
  it( 'is configured correctly', async () => {
    await VersionPage.open();

    // this is just a sample assertion, checking if an element exists
    assert( await VersionPage.extension.isExisting() );

  } );

} );

Typical

[edit]

Typical patch will have a few more files. You will need these files if this is the first Selenium test in the repository.
