In addition, headless is not the perfect solution for debugging purposes, since the test will not be visible to you. As it does not mimic real users interactions and workflows as well as regular chromeDriver mode, it’s difficult to catch bugs that are related to crashing images, because the UI isn’t displayed. Headless testing itself also has disadvantages. In addition, if you are used to running your tests in regular Chrome, you will also need to adjust, and transferring your tests will require additional work and tweaking. Second, since headless Chrome is rather new in the headless section, it may raise unknown issues for the community. Unlike Chromium or PhantomJS, headless browsers that the community contributed to their development, Google is the only entity that will contribute to Chrome headless development. Headless Chrome ConsĬhrome headless has limitations compared to other headless browsers. Chrome headless API has recently developed another cool open source tool designed to handle these types of tests, called Puppeteer. You can use headless testing to automate the rendering and screen capturing of your website images and to perform layout checks in an automated fashion. If you wish to monitor your network application performance, headless can be a good solution for you. Headless Is Ideal for Monitoring Your Network Application Performance

Since it’s just data you’re looking for, it doesn’t make sense to start up a full instance of a browser. If you wish to scrape the HTML of a webpage regardless of its CSS and JavaScripts, for example, if you want to scrape an HTML for future data that will be used later, headless browser testing can be a great solution.

This way, developers, can quickly feel confident that their code didn’t break the webpage’s functionality. Running Headless Tests Is Quicker for Developersīeing able to run tests straight from the command line can save a lot of time for developers who want to verify their code quickly and don’t need GUI intervention. In my experience, this will not always be much faster, but it is faster than real browsers. Headless Browsers Are Fasterįor the same reason as the previous point, headless browsers are also quicker to start running tests. This will enable you to run more tests, and your tests to run faster and smoother. The big advantage of headless testing is that it starts performing functions even if your page hasn’t finished loading, taking up less resources. This is a huge problem especially when you are testing multiple browsers and a number of tabs. Rendering and opening HTML, CSS, Javascript and images takes up a lot of resources. This blog post is based on the webinar I gave “Driving Headless and Chrome with Selenium and Python.” Headless Chrome Pros 1. But first, let’s learn a bit more about the pros and cons of headless testing in general, and Chrome headless in particular.

In this blog post, I will show you how to run a headless Chrome test with Selenium WebDriver and Allure. It can also execute JavaScript like AJAX requests. Just like a regular browser, a headless browser understands HTML and CSS. Headless testing is useful for verifying text, elements or other static data on a certain webpage. Headless tests are executed from a command-line interface or by using network communication, and they run the functions in the backend. Since headless browsers don’t have a graphical user interface (GUI), they saves resources and time. Generally speaking, headless Chrome browsers are web browsers that are used for testing usability and browser interactions. As Google put it, it’s like “running Chrome without Chrome!” This provides testers with all the speed advantages of the Chrome V8 engine, but without having to use a GUI. If not, it’s time to catch up, because since then, headless testing has been available through Chrome. I assume you’ve all heard Google’s announcement from last year about shipping Headless Chrome in Chrome 59.
