XPath is designed to allow the navigation of XML documents,with the purpose of selecting individual elements, attributes, or some other part of an XML document for specific processing.
What is XML?
The Extensible Markup Language (XML) is the context in which the XML Path Language, XPath, exists.
XML provides a standard syntax for the markup of data and documents.
It is a mechanism which involves more than one components to work parallel with Each other.
Generally in Test Automation, we have two components
1. Application Under Test
2. Test Automation Tool.
Both these components will have their own speed. We should write our scripts in such a way that both the components should move with same and desired speed, so that we will not encounter "Element Not Found" errors which will consume time again in debugging.
Synchronization can be classified into two categories:
To start selenium scripting with Eclipse, you need to first install Java Development Kit (JDK) Download and Install Java
Installing eclipse is very easy, First download eclipse . The downloaded file should be a .zip file. Place it in a folder and ensure that you have full read and write permissions. Try to create a shortcut of the eclipse executable file.
To run selenium webdriver in IE browser, we need InternetExplorerDriver which is a standalone server which implements WebDriver's wire protocol.
First of all, download latest version of IEDriver server for webdriver. You can download latest version server from Download InternetExplorerEDriver
Normally to run webdriver, we just need a browser and a selenium server jar file. Selenium 2 by-default supports Mozilla Firefox browser. Then the next question come to your mind is How to run webdriver in other browsers.
Selenium supports to run webdriver in other browsers by just adding an .exe path of the driver server for the individual browsers.
Selenium webdriver uses 8 locators to find the elements on web page. The following are the list of object identifier or locators supported by selenium.
We have prioritized the list of locators to be used when scripting.
id Select element with the specified @id attribute.
Name Select first element with the specified @name attribute.
Linktext Select link (anchor tag) element which contains text matching the specified link text
What is HTML?
As you know HTML Hyper Text Markup Language used for describing web pages. The basic structure of an HTML document includes tags, attributes and elements.
Each tag represents a document content. HTML contains tags with angle brackets like <html > and plain text. There are two tags one is start tag and second tag is end tag. Every tag should end with a forward slash before the tag name.
Syntax:
Selenium is a web Automation tool which can used to perform testing ONLY on Web Applications not Desktop based applications.
There are others tool which can be used to automate both web applications and windows applications like QTP (Quick Test Professional) . As every one aware that QTP is Licensed Tool AND Selenium is Open source tool, download it configure it and enjoy.
