In this blog, we'll be equipping you with everything you need to know about WebdriverIO, from its key features to setup and best practices. 

 

What is WebdriverIO? 

WebdriverIO is a next-generation test automation framework built specifically to address the complexities of modern web and mobile application testing. It's a Node.js based solution that seamlessly adheres to the WebDriver protocol, a W3C standard that facilitates communication between your test scripts and various web browsers. Think of WebdriverIO as your trusty robot companion designed to interact with your web applications exactly as a human user would. 

 

Why Use WebdriverIO for Automation Testing? 

WebdriverIO stands out as a powerful choice for both web testing services and mobile app testing services, offering several advantages that streamline and enhance automation testing: 

  • Open-Source Efficiency: WebdriverIO's open-source nature promotes customization, community support, and cost-effectiveness for teams seeking a test automation solution. 

  • Cross-Platform Power: Effortlessly test your web and mobile applications across a multitude of browsers, operating systems, and device configurations, ensuring consistent user experiences and maximizing your test coverage. 

  • Native App Support (with Appium): Extend your automated testing reach to iOS and android mobile apps, centralizing your mobile testing services within a unified framework. 

  • Simplified Interactions: WebdriverIO offers intelligent element interaction strategies, making it easier to test even complex web applications built with technologies like React, as well as components nestled within shadow DOMs. 

  • Intelligent Waiting: Minimize frustrating manual timeouts! WebdriverIO gracefully waits for elements on a page to become available before execution, leading to more reliable and robust automated tests. 

  • Thriving Ecosystem: WebdriverIO boasts a vibrant and supportive community, offering a wealth of resources, plugins, and assistance to enhance your automation testing service. 

 

Underlining The WebdriverIO Process 

At its core, WebdriverIO leverages the WebDriver protocol, a W3C standard, to enable seamless communication with web browsers and mobile devices: 

  • Crafting Your Test Scripts: You write your test scenarios in JavaScript, outlining the specific steps a user would take within your web or mobile application. These include actions like interacting with elements, filling forms, and navigating between pages. 

  • Translation via WebDriver Protocol: WebdriverIO acts as a skilled translator, converting your JavaScript test instructions into standard WebDriver commands. This ensures your commands are understood by various browsers and devices. 

  • Execution on the Device: The targeted browser (e.g., Chrome, Firefox) or mobile device receives these WebDriver commands and meticulously executes the simulated user actions. 

  • Collecting Feedback: WebdriverIO gathers essential details about the results of these interactions, including the state of elements and the outcomes of your actions. 

  • Assertions for Verification: Within your test scripts, you define assertions to check if your application behaves as intended. WebdriverIO compares the collected feedback to these assertions, flagging any discrepancies. 

 

Step-by-Step Guide To First automation test suite 

Setting up your initial WebdriverIO test suite is remarkably straightforward. Just as we did in our step-by-step guide to QA automation testing, we aim here to assist testers to enhance their automation testing solutions. So, let's walk through the WebdriverIO’s automation test suite: 

1.  Prerequisites: 

Ensure you have Node.js and npm (or yarn) installed on your system.   

Node Installation:  Visit Node JS website and download the latest LTS version.    

Once the installation is complete, check if Node.js and npm are correctly installed on the machine by opening the terminal and typing the following commands:node –v and npm –v. 

 

 

2.  Project Setup: 

Create a new project directory and leverage the WebdriverIO CLI (npx wdio config) to rapidly generate a project structure. This wizard will guide you through essential configurations.  

  • Install WebDriverIO command-line interface  

To install WebDriverIO CLI, type the following command in the terminal “npm i — save-dev @wdio/cli”. When the installation is complete, it will display the details of the package added.  

 

 

  • Create a WebDriverIO Config File  

To execute test scripts using WebDriverIO, create a config file that contains the details of the tests, capabilities, and settings. To do so, enter the following command in the power shell:  npx wdio config 

  • The wdio config wizard opens.  

 

 

 

  • Provide the required details such as the automation backend, framework, reporting tool, etc. Following is the snapshot of the configuration I selected during setup  

 

 

 

  • In the WebdriverIO configuration wizard, you have the freedom to select your preferred testing framework, whether it's Mocha, the behavior-driven development (BDD) approach with Cucumber, or the Jasmine framework. 

 

 

 

  • After selecting the configuration, the wizard will install required packages and display the message that the package is successfully installed, and the configuration file is created successfully. 

 

 

 

  • Now your project structure will look like this  

 

 

 

  • Your spec file and page object will now look like this   

 

  

  

3.  Test Script Creation:  

Within the generated 'test/specs' folder, create JavaScript files for your test scenarios. Define interactions with your web or mobile application's elements (buttons, forms, etc.), and clearly assert the expected outcomes of these interactions.  

  

4.  Execution:  

Run your tests using the WebdriverIO CLI (e.g., npx wdio run). For comprehensive cross-platform coverage, consider integrating an automation testing service provider like BugRaptors to access a vast array of real devices and browsers in the cloud.  

 

5.  Analyze Reports:  

WebdriverIO generates informative reports to help you understand test results, quickly identify failures, and troubleshoot issues.  

Here we have integrated spec reporter which looks like this. 

 

 

These reports are crucial for making data-driven decisions and further refining your test cases. So, integrate your framework with the reporting tool of your choice, whether Allure, Dot, Junit, or any other. 

 

Pros & Cons of WebdriverIO 

Although WebdriverIO is well-liked in the test automation community, it has advantages and disadvantages just like all the other AI automation testing tools in the market. Let's explore the main factors influencing its practical application in the real world:
