Selenium – Understanding Object Identification

In previous two posts I have explained how to setup a sample web application, recording and playing back tests with Selenium IDE.  Now, we will understand how Selenium identifies the objects on the Application Under Test.

To identify the objects such as Links, Buttons, Edit boxes, Drop downs, etc on the application Selenium uses a concept called “Locators”.  There are around 8 different types of locators.  Out of them, I will be explaining only four as they are widely used while automating the test cases using Selenium.

  1. id = id – By default Selenium IDE takes “id” as Locator

Every Web Page will be having some HTML Source code.  This can be viewed using “View –> Page Source / View source” on the browser. In the following picture we can see “id” attribute of a HTML tag is used as a locator to identify an object.


2.  name = name (Second locator)

We will do the following steps to understand how exactly Selenium identifies the objects:

  1. Start Selenium IDE from Tools menu of the browser
  2. Login to sample application – Sugar CRM
  3. Click on Accounts tab
  4. Click on Create Account link
  5. Now Create Account Page gets displayed

Selenium IDE has recorded all these steps.  In the following pictures all the steps above can be seen.



In the following picture we can see the “name” property of the object is used as Locator to identify the object.


3. xpath = xpathExpression.  Xpath is used as a Locator to identify an object.  This is an expression which is formed by combining various HTML tags.  For example: //a[contains(text(),’VRL travels’)], //div[@id=’shortcuts’]/span/span[2]/a/span


4.  link=link text (in HTML source we can located this using “href” tag)


I hope you have understood how Selenium identifies objects using different Locators with all of the above screenshots & explanation.

Please provide me your valuable suggestions through comments.

  • hi
    i’m very new to selenium , so if my doubt is silly please excuse me , in the syntax for xpath what actually the span is, n what is the use of this object identification

    • raj,

      no worries.. let me explain you the xpath. In HTML source we can find lot of html nodes / tags. If you look at the source from top to bottom, and start combining them one after the other to reach a particular element that is xpath. Span is a HTML tag. Both Div and Span are used in html source which are primarily used to different blocks on the web page. You can read further on these tags in

      I hope this answers your question.

  • Hello Sir,
    This is ramana. I want to learn selenium but i am very poor in java. Is there any effect on me if i dont know that?. Is there any way to quickly learn selenium . I just saw u r website. Its good. I want this concepts little more clearly. R u providing any materials here to learn?

  • Hi Sitaram,

    Your way of explanation and examples are very useful for everyone but i think you forgot to explain object identification using CSS. Selenium is browser independent for that reason everyone would prefer to CSS. If you explain object identification using CSS that is very useful.
    And this is my suggestion only.
