Lesson 7 - Java Testing - Selenium WebDriver Syntax Overview

In the previous lesson, Java testing - Unit tests of real applications III, we learned to implement the PageObject design pattern in Java using Selenium. In today's tutorial, we're going to describe the RemoteWebDriver API in detail and other related objects and interfaces.

RemoteWebDriver

The base of specific drivers for different browsers is the RemoteWebDriver class. ChromeDriver, FirefoxDriver, or other drivers inherit from this class. The class implements several interfaces, their names should tell what they are used for, let's take a look:

• WebDriver
• JavascriptExecutor
• FindsById
• FindsByClassName
• FindsByLinkText
• FindsByName
• FindsByCssSelector
• FindsByTagName
• FindsByXPath
• HasInputDevices
• HasCapabilities
• Interactive
• TakesScreenshot

The public methods will be much more important to us. Let's describe which methods we can call on a ChromeDriver instance and what they do.

• close() - Closes the browser window. If the last window is closed, the browser is closed.
• findElement(By by) - Finds an element on the page using a selector passed by a static method on the By class. This is the preferred way to select elements and includes all the methods that we'll mention when describing RemoteWebDriver below.
• findElements(By by) - Finds elements on the page corresponding to a given selector. The method returns an ordinary List, so we get to the first element via .get(0) and so on.
• get(java.lang­.String url) - Loads a new page in the current window from a given URL.
• getCurrentUrl() - Returns the current URL.
• getTitle() - Returns the title of the current page.
• getWindowHandle() -
