Lesson 4 - Testing in C# .NET - Selenium WebDriver syntax overview
In the previous lesson, Testing in C# .NET - Finishing unit tests and best practices, we learned to implement the PageObject design pattern in C# .NET 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:
IWebDriver
ISearchContext
IDisposable
IJavaScriptExecutor
IFindsById
,IFindsByClassName
,IFindsByLinkText
,IFindsByName
,IFindsByTagName
,IFindsByXPath
,IFindsByPartialLinkText
,IFindsByCssSelector
ITakesScreenshot
IHasInputDevices
,IHasCapabilities
,IHasWebStorage
,IHasLocationContext
,IHasApplicationCache
,IHasSessionId
IAllowsFileDetection
IActionExecutor
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 theBy
class. This is the preferred way to select elements and includes all the methods that we'll mention when describingRemoteWebDriver
below.FindElements(By by)
- Finds elements on the page corresponding to a given selector. The method returnsReadOnlyCollection
, which is essentially aList
whose items cannot be modified.Url
- Astring
property. Returns the current URL. When set loads a new page from the passed URL in the current window.Title
- Property, returns the title of the current page.CurrentWindowHandle
-
