How to Parameterize Your Tests in WebdriverIO

About The Video

In part 7 of the WebdriverIO tutorial series, join 𝐌𝐚𝐫𝐜𝐨 𝐀 𝐂𝐫𝐮𝐳, founder of automateNow, as he demonstrates how to perform parameterization in WebdriverIO. You will learn how to integrate different test scenarios and configure the page object. Marco also explains how to create test data, leading to the final creation of the test.

By the end of this tutorial, you will be able to run automated tests multiple times with different sets of data. This approach will help you ensure your application behaves as expected with various input values and scenarios, improving test coverage and reliability.
