@wdio/globals

What is @wdio/globals?

@wdio/globals is a package that provides global variables and functions for WebdriverIO, a popular automation test framework. It simplifies the setup and usage of WebdriverIO by offering a set of globally accessible utilities.

What are @wdio/globals's main functionalities?

Global Browser Object

The global `browser` object allows you to interact with the browser instance directly. This includes navigating to URLs, interacting with elements, and more.

browser.url('https://example.com');

Global Expect Function

The global `expect` function is used for assertions in your tests. It allows you to make assertions about the state of the browser or elements within it.

expect(browser).toHaveTitle('Example Domain');

Global $ and $$ Functions

The global `$` and `$$` functions are shorthand for selecting single and multiple elements, respectively. They simplify the process of element selection in your tests.

const element = $('selector'); const elements = $$('selector');

selenium-webdriver

Selenium WebDriver is a widely-used tool for browser automation. It provides a more low-level API compared to WebdriverIO, requiring more boilerplate code to achieve similar tasks.

cypress

Cypress is an end-to-end testing framework that offers a more developer-friendly experience with automatic waiting and a more intuitive API. However, it is limited to testing within the browser and does not support multiple browser instances.

nightwatch

Nightwatch.js is an end-to-end testing framework built on top of Selenium WebDriver. It provides a higher-level API compared to Selenium WebDriver but is not as feature-rich or user-friendly as WebdriverIO.

WDIO Globals

A helper utility for importing global variables directly

This package can be used to import global variables explicitly, e.g.

import { browser, $, $$, expect } from '@wdio/globals'

describe('my test', () => {
    // ...

    it('can do something', async () => {
        // ...
    })

    // ...
})
