PhantomJSįor many years, PhantomJS was a great choice. Since many pages won’t load at all without JavaScript, this shows the need for a headless driver with better JavaScript support. After spitting out a whole pile of JavaScript warnings, it fails with EcmaError: TypeError: Cannot call method "then" of undefined. However, uncommenting the line that enables JavaScript is a different story. filter(city -> im().startsWith(“New York”))ĪssertEquals(1, newYorkCity.size(), “New York is an upcoming city”) map(element -> element.getAttribute(“innerText”)) Set newYorkCity = driver.findElements(By.className(“qcon”)) This example is available in both Java 8 and Java 11 versions in the GitHub repo. It works because InfoQ’s home page is designed to be functional without JavaScript.
#GHOST BROWSER TESTING HOW TO#
The following code shows how to run a basic test that uses Selenium with HtmlUnitDriver. It’s still a good choice for web pages with a good amount of HTML data on them. You have the ability to choose whether to run the page JavaScript, it runs in memory and is very fast. Prior to Single Page Applications and largely AJAX based pages, this driver was an excellent choice. While this driver is still supported, it is now a separate dependency and, unsurprisingly, uses the Html Unit framework. In the past, Selenium came with a built in headless driver called HtmlUnitDriver. HtmlUnitDriver – the initial headless driver
That way you can visually see where things go haywire. It is really helpful when debugging a Selenium script to temporarily turn off headless mode and watch the program run. For example, both Chrome and Firefox have the option to run in headless mode. One the other hand headless browsers that require a “real” browser to be installed are great for development.
