June ‘21 Updates: Live With Cypress Testing, LT Browser Made Free Forever, YouTrack Integration &#038; More!

Howdy testers! June has ended, and it’s time to give you a refresher on everything that happened at LambdaTest over the last month. We are thrilled to share that we are live with Cypress testing and that our very own LT Browser is free for all LambdaTest users. That’s not all, folks! We have also added a whole new range of browsers, devices & features to make testing more effortless than ever.

Desired Capabilities in Selenium Webdriver

Desired Capabilities is a class used to declare a set of basic requirements such as combinations of browsers, operating systems, browser versions, etc. to perform automated cross browser testing of a web application.

And the Winner Is: Aggregate Model-based Testing

In my last blog, I investigated both the stateless and the stateful class of model-based testing. Both have some advantages and disadvantages. You can use them for different types of systems, depending on whether a stateful solution is required or a stateless one is enough. However, a better solution is to use an aggregate technique that is appropriate for each system. Currently, the only aggregate solution is action-state testing, introduced in the book Paradigm Shift in Software Testing. This method is implemented in Harmony.

Difference Between Web And Mobile Application Testing

Smartphones have changed the way humans interact with technology. Be it travel, fitness, lifestyle, video games, or even services, it’s all just a few touches away (quite literally so). We only need to look at the growing throngs of smartphone or tablet users vs. desktop users to grasp this reality.
