Testcafe vs WebdriverIO

TestCafe and WebdriverIO are both popular tools for testing web apps. In this article, let’s understand the differences between Testcafe and WebdriverIO and see why all-around cloud test automation tools like Testsigma are always a better alternative.

Check out how Testsigma compares with other test automation tools.

Testcafe vs WebdriverIO – Overview

What is Testcafe?

TestCafe is a free and open-source tool for testing web apps from end to end. It uses Node.js so it doesn’t need WebDriver or any extra browser stuff. It makes setting up and running tests easy. Unlike old testing tools, TestCafe uses a proxy-based system to handle and change test commands. This lets it work with different browsers without needing separate drivers. Because of this, tests run smoothly and are more reliable, even for complex apps.

One big advantage of TestCafe is its smart waiting. It waits for things to show up on the page before doing anything that stops tests from going wrong. It works well with tools like Jenkins, GitHub Actions, and GitLab CI/CD. It provides an easy way to write tests for both technical and non-technical members. But it can’t perform mobile testing. Moreover, you can’t control the browser like with WebDriver which could be a problem for some teams needing that kind of control.

What is WebdriverIO?

WebdriverIO is a modern tool for testing browsers and mobiles, made with Node.js. It uses the WebDriver which is a standard way to control browsers, so our tests are simulated just like real users are using the applications. This way, our tests are more true to life and reliable.

We can also use WebdriverIO to test native mobile apps with Appium. Being open-source, lots of people help make it better, adding more plugins and features. This makes WebdriverIO good for testing on many different platforms.

WebdriverIO is good for developers because it has a simple API, thus, writing and maintaining tests is not hard. We can choose from Mocha, Jasmine, or Cucumber for how we want to write our tests. It’s scalable and built in a way that helps big projects grow and is easy to maintain.

It has a smart wait feature to load and a useful command line tool to make testing easier.
