Enhanced Test Automation with WebdriverIO

By: Paul M. Grossman, Larry C. Goddard

Overview of this book

This book helps you embark on a comprehensive journey to master the art of WebdriverIO automation, from installation through to advanced framework development. You’ll start by following step-by-step instructions on installing WebdriverIO, configuring Node packages, and creating a simple test. Here you’ll gain an understanding of the mechanics while also learning to add reporting and screen captures to your test results to enhance your test case documentation. In the next set of chapters, you’ll delve into the intricacies of configuring and developing robust method wrappers, a crucial skill for supporting multiple test suites. The book goes beyond the basics, exploring testing techniques tailored for Jenkins as well as LambdaTest cloud environments. As you progress, you’ll gain a deep understanding of both TypeScript and JavaScript languages and acquire versatile coding skills. By the end of this book, you’ll have developed the expertise to construct a sophisticated test automation framework capable of executing an entire suite of tests using WebdriverIO in either TypeScript or JavaScript, as well as excel in your test automation endeavors and deliver reliable, efficient testing solutions.

Timeout – delay of game

The default timeout for a WebdriverIO expect matcher is 3 seconds and the interval is 100 ms. That is 30 checks over 3 seconds, which is far better than waiting 30 seconds as is the industry standard. Remember we are using the pageSync() method to burn the time that the page uses to build. It makes sense that our assertions should be available almost immediately. To adjust the timeout and interval of the expect-webdriverio assertion, we can make a change in the WebdriverIO hooks section of the wdio.config.ts file:

before: function (capabilities, specs){
require('expect-webdriverio').setOptions ({wait:5000, interval: 250});
}

This code will now change our expect assertions to be executed 20 times. The wait timeout will be 5 seconds. The check will be performed every 1/4 second:

Spec Files: 0 passed, 1 failed, 1 total (100% completed) in 00:00:05

The resulting time is now reduced to an optimal amount. It is just a second, but a little...
