WebdriverIOArchitecture: HowDoes It
Work?
WebdriverIO is developed on NodeJS and utilizes the JSON Wire
Protocol for communication. Distributed through npm, WebdriverIO
leverages NodeJS, which is open-source and extensively used for
application development. It employs a RESTful architecture to
facilitate automation testing.
Test scripts are written in JavaScript using the WebdriverIO library.
The service request is transmitted via NodeJS as an HTTPcommand
utilizing the JSON Wire Protocol. The services module then forwards
the request to the browser.
Upon receiving the command, the browser executes the specified
user actions, therebyvalidating the application’s functionality.

Prerequisite Stepsto Create aWDIO +
JavaScript Project
Throughout this blog, the following versions of libraries and
applications were utilized in our practical examples.
Visual Studio Code [Version 1.89]
Npm [Version 10.5.2]
Node [20.13.1]
Setting up a WebdriverIO (WDIO) project with JavaScript involves
several key steps. Below are the prerequisite steps to get started:
▶️
Download & InstallVisual Studio Code

6. Next, downloadVisual Studio Code (VS Code) from it’s official
site and install it.
▶️
Install Node.js and npm
Ensure that Node.js and npm (Node Package Manager) are
installed on your machine. You can download and install Node.js
from the officialwebsite. Note that npm is bundled with
Node.js.
▶️
Create a NewProject Directory
Begin by creating a new directoryforyour project and navigating
into it. You can use the following commands forthat: “mkdir
wdio-js-project” and “cdwdio-js-project”.
To initialize a WebdriverIO project, hit this command in your
project directoryterminal: ”npm initwdio@latest .”
ifyou want to create a new project in a specific directory, you
can use: “npm initwdio@latest ./path/to/new/project”

7. ▶️
Install WebdriverIO CLI
Install the WebdriverIO CLI tool globallyto facilitate project
configuration. Run this cmd command “npm install –save-dev
@wdio/cli”.

8. ▶️
Run WebdriverIO Configuration Wizard
Execute the WebdriverIO configuration wizard to set up your
project. This interactive tool will guide you through selecting
your preferred framework, reporter, and other configurations. Hit
this “npxwdio config” in the terminal and followthe
instructions.
During configuration, you will be prompted to select various
options, such as the test runner (e.g., Mocha, Jasmine,
Cucumber), reporter (e.g., Spec, Allure), and services (e.g.,
Chromedriver, Selenium Standalone, Appium).
▶️
AConfiguration steps forsetup framework
Depending on your chosen configurations, you need to provide
answers as belowforthe following setup questions based on
your requirements.

9. ▶️
Set Up WebdriverIO Configuration File
Upon finalization, the configuration wizard will produce a
“wdio.conf.js” file within your project directory. Take the opportunity
to review and adjust this file according to your project requirements.
Below is a basic example:
[wdio.conf.js]
export const config = {
runner: 'local',
specs: [
'./test/specs/**/*.js'
],
exclude: [
// 'path/to/excluded/files'
],
maxInstances: 10,
capabilities: [{
browserName: 'chrome'
}],
logLevel: 'info',
bail: 0,
waitforTimeout: 10000,
connectionRetryTimeout: 120000,
connectionRetryCount: 3,
services: ['chromedriver'],
framework: 'mocha',
reporters: ['spec',['allure', {outputDir: 'allure-results'}]],
mochaOpts: {
ui: 'bdd',
timeout: 60000
},
}

10. ▶️
CreateTest Specifications
Establish a directoryforyourtest specifications (e.g., test/specs) and
compose yourtest scripts in JavaScript. Below is a straightforward
example:
[contactUsTests.js]
import { expect, browser, $ } from '@wdio/globals'
describe('Contact Us', () => {
it('verifyThatContactusFormSubmittedSuccessfully', async () =>
{
await browser.url(`https://jignect.tech/contact-us/`);
await browser.maximizeWindow();
await $("//p//input[@type='submit']").click();
await expect($("//div[contains(@class,'response-
output')]")).toBeDisplayed();
})
})
➡️Let’s analyze each line ofthetest script and explain its
functionality:
import { expect, browser, $ } from ‘@wdio/globals’: This line
imports essential functions and objects from the @wdio/globals
package.
expect is used for assertions.
browser represents the browser instance to control
browser interactions.
$ is a shorthand for selecting elements using a CSS or
XPath selector.
describe(‘Contact Us’, () => {: This defines a test suite named
‘Contact Us’. The ‘describefunction groups the related tests,
making it easierto organize and manage them.
The ‘it’ function defines an individual test case named

11. “verifyThatContactusFormSubmittedSuccessfully” and
Used to specify a single test. The ‘async’ keyword allows the use
of ‘await’ within the test, enabling asynchronous operations.
The ‘browser.url’ command navigates the browserto the
specified URL (https://jignect.tech/contact-us/). The await
keyword ensures that the browserwaits forthe navigation to
complete before proceeding.
The ‘browser.maximizeWindow’ command maximizes the
browserwindowto ensure that all elements are visible and
interactable. Again, await ensures that the test waits forthe
windowto maximize before continuing.
The await ‘$(“//p//input[@type=’submit’]”).click();’ line
selects the submit button and clicks it to submit the form.
The ‘expect’ and ‘toBeDisplayed()’ assertion verifies that a div
element containing the class ‘response-output’ is displayed on
the page, indicating that the form submission was successful
and closing braces complete the test case and the test suite
definitions.
Running theTest Script
Once yourtest script is prepared, you can execute it by run the
following “npxwdiowdio.conf.js” command in the Command
Prompt:
