Organizations build their digital presence by developing websites or web applications to reach a wider audience. This, in turn, leads to competition with the existing players in the market. As the new web applications roll into the market, they try to grab their share of the audience. However, to stay competitive, the existing web applications must also add new features to enhance their user experience.

One of the significant challenges the QA team faces while testing web applications is ensuring that the existing and new functionalities work fine when rendered across browsers and devices. Therefore, it is essential to perform cross browser testing. Additionally, devs and testers should use automated browser testing to expedite their browser testing process.

To make your automated web testing more productive than ever, we at LambdaTest are thrilled to announce our integration with Siesta by Bryntum -a JavaScript and UI testing tool for web pages and Node.js processes.

The LambdaTest and Siesta integration allow you to perform automated testing of websites or web apps on an online browser farm of 3000+ browsers and operating system combinations.

What is Bryntum’s Siesta?

Siesta by Bryntum is a JavaScript and UI testing tool for web pages and Node.js processes. You can run tests in browsers, Node.js, and Deno on Linux, macOS, and Windows. Siesta includes a powerful event recorder and player and an extensible automation package with cloud testing capabilities.

What is Bryntums Siesta

Siesta comes in two editions – Lite and Standard.

  • Lite: Using the web interface, you can run your tests in Node.js and manually in any supported browser. Except for native simulations, you can record and replay user actions.
  • Standard: It offers native events, browser automation, and integrations with all browsers.

Why use Siesta to automate web testing?
