Not all headless browsers are suited for the same testing scenarios, so you may have to try several different options to find the right combination of tools for your development needs. You want a lightweight solution with very little draw on resources so that you can run it in the background without slowing down development work, but the same solution must allow you to execute every test necessary to simulate the expected actions of target users. Keep this in mind as you evaluate popular headless browsers. Any problem impeding a smooth experience for users can undermine the success of the site. An increased focus on engagement creates more elements with which users can interact, and ecommerce sites, in particular, can require complex multi-level flows for proper navigation. Today's websites present a number of complex use cases developers didn't have to think about in the past. Testing these use cases provides you with a solid overview of how a site's UI performs and gives you essential information for making changes before deployment. In a headless testing environment, you can write and execute scripts to: Each point at which a user types, clicks or otherwise interacts with on-page elements is a point at which something could go wrong, and you're better off finding out about and fixing problems in the testing stage than discovering glitches weeks or even months later when complaints come pouring in. What use cases should you test with headless browsers? Consider the most frequent actions users may take on any given page.
Since the experience of the end user is paramount in today's highly personalized web environment, it's crucial to work out as many bugs as possible before launching the public version of a site. These actions help developers confirm whether or not common website activities flow smoothly and can identify potential problems with UI and UX. Running one or more automated UI tests in the background.Instead of testing a site or performing common actions using familiar graphical elements, use cases are automated and tested with a command-line interface. Headless browsing may seem like an odd term, but it's simply a name for a browser or browser simulation without the recognizable graphical interface. Familiarize yourself with the benefits of headless testing, and learn more about the possibilities available so that you can select the best browsers to use for web development and testing. Many headless options are available, including headless versions of popular browsers like Chrome and Firefox and tools to simulate several different browsers. How do you know if the user interface (UI) of a website you're developing works as it should and the site as a whole delivers the optimal user experience (UX)? Headless browsers give you a fast, lightweight way to automate high-level actions and get an idea of how well your site operates in common scenarios.
